Warranty......................................................................................................... 61 VI LAUNCH Professional 919X User Manual 1 Overview 1.1 Vehicle Coverage This diagnostic tool is specially designed to work with all OBD II compliant vehicles, including Controller Area Network (CAN). It is required by EPA that all 1996 and newer vehicles (cars and light trucks) sold in the United States must be OBD II compliant and this includes all American, Asian and European vehicles. A small number of 1994 and 1995 model year gasoline vehicles are OBD II compliant. To verify if a 1994 or 1995 vehicle is OBD II compliant, check the following: 1. Vehicle Emissions Control Information (VECI) Label. It is located under the hood or by the radiator of most vehicles. If the vehicle is OBD II compliant, the label will designate OBD II Certified. 2. Government regulations mandate that all OBD II compliant vehicles must have a "common" 16-pin Data Link Connector (DLC). Note: Some 1994 and 1995 vehicles have 16-pin connectors but are not OBD II compliant. Only those vehicles with a Vehicle Emissions Control Label stating OBD II Certified are OBD II compliant. 1 LAUNCH Professional 919X User Manual 1.2 On-Board Diagnostics (OBD) II Note: With the exception of some 1994 and 1995 vehicles, most vehicles from 1982 to 1995 are equipped with some type of first generation On-Board Diagnostics. OBD II is an early warning system designed to monitor engine, transmission, and emissions control components by performing specific diagnostic test. When a fault condition is detected, the system captures important data and activates the "Check Engine" light. If the light comes on, the vehicle might have a condition that wastes fuel, shortens engine lift, or causes excessive air pollution. If the problem that caused the light to come on is addressed, for instance a loose gap is tightened, the light will go out. If the light comes on and stays on, a minor engine fault condition is occurring and should be addressed as soon as possible. If the light is blinking, a severe engine fault condition is occurring and should be addressed immediately. The diagnostic tool connects to the vehicle's computer system and captures information that can help identify the fault condition. 1.3 OBD II Definitions The following terms and their definitions are related to OBD II systems. Read and reference this list as needed to aid in the understanding of OBD II systems. EOBD - European On-Board Diagnostics. Essentially the same as OBD II, with the same Data Link Connector and Communication Protocols. Communication Protocols - Allows different systems and sensors in a vehicle to communicate. There are currently five protocols: CAN Bus J1850 VPW ISO 9141-2 J1850 PWM ISO 14230 KWP Powertrain Control Module (PCM) -- The PCM is the OBD II accepted term for the vehicle's "on-board computer." In addition to controlling the engine 2 LAUNCH Professional 919X User Manual management and emissions systems, the PCM also participates in controlling the powertrain (transmission) operation. Most PCMs also have the ability to communicate with other computers on the vehicle (ABS, ride control, body, etc.). DLC -- Data Link Connector. The 16-cavity connector on the vehicle that allows communication between the computer system and the diagnostic tool. MIL -- Malfunction Indicator Lamp. The vehicle's "Check Engine" warning light that activates when a DTC is stored. DTC -- Diagnostic Trouble Code. A code stored in the computer system's memory, which helps to identify the fault condition that is causing the MIL to activate. Freeze Frame Data -- Operating conditions that are stored when a DTC is stored. PID -- Parameter Identification Data. Data returned by the vehicle's control modules to the diagnostic tool. Monitors -- Monitors are "diagnostic routines" programmed into the PCM. The PCM utilizes these programs to run diagnostic tests, and to monitor operation of the vehicle's emissions-related components or systems to ensure they are operating correctly and within the vehicle's manufacturer specifications. Currently, up to fifteen Monitors are used in OBD II systems. Additional Monitors will be added as the OBD II system is further developed. Note: Not all vehicles support all fifteen Monitors. Enabling Criteria -- Also termed Enabling Conditions. They are the vehiclespecific events or conditions that must occur within the engine before the various monitors will set, or run. Some monitors require the vehicle to follow a prescribed "drive cycle" routine as part of the enabling criteria. Drive cycles vary among vehicles and for each monitor in any particular vehicle. Please refer to the vehicle's factory service manual for specific enabling procedures. Trip - A Trip for a particular Monitor requires that the vehicle is being driven in such a way that all the required "Enabling Criteria" for the Monitor to run and complete its diagnostic testing are met. The "Trip Drive Cycle" for a particular Monitor begins when the ignition key is turned "On." It is successfully completed when all the "Enabling Criteria" for the Monitor to run and complete its diagnostic testing are met by the time the ignition key is turned "Off." Since each of the fifteen monitors is designed to run diagnostics and testing on a 3 LAUNCH Professional 919X User Manual different part of the engine or emissions system, the "Trip Drive Cycle" needed for each individual Monitor to run and complete varies. Drive Cycle -- A specific mode of vehicle operation that provides conditions required to set all the readiness monitors applicable to the vehicle to the "ready" condition. The purpose of completing an OBD II drive cycle is to force the vehicle to run its onboard diagnostics. Some form of a drive cycle needs to be performed after DTCs have been erased from the PCM's memory or after the battery has been disconnected. Running through a vehicle's complete drive cycle will "set" the readiness monitors so that future faults can be detected. Drive cycles vary depending on the vehicle and the monitor that needs to be reset. For vehicle specific drive cycle, consult the service manual. Note: Do not confuse a "Trip" Drive Cycle with an OBD II Drive Cycle. A "Trip" Drive Cycle provides the "Enabling Criteria" for one specific Monitor to run and complete its diagnostic testing. An OBD II Drive Cycle must meet the "Enabling Criteria" for all Monitors on a particular vehicle to run and complete their diagnostic testing. Warm-up Cycle - Vehicle operation after an engine off period where engine temperature rises at least 40°F (22°C) from its temperature before starting, and reaches at least 160°F (70°C). The PCM uses warm-up cycles as a counter to automatically erase a specific code and related data from its memory. When no faults related to the original problem are detected within a specified number of warm-up cycles, the code is erased automatically. Fuel Trim (FT) - Feedback adjustments to the base fuel schedule. Short-term fuel trim refers to dynamic or instantaneous adjustments. Long-term fuel trim refers to much more gradual adjustments to the fuel calibration schedule than short-term trim adjustments. These long-term adjustments compensate for vehicle differences and gradual changes that occur over time. 1.4 Diagnostic Trouble Codes (DTCs) OBD II Diagnostic Trouble Codes are codes that are stored by the on-board computer diagnostic system in response to a problem found in the vehicle. These codes identify a particular problem area and are intended to provide you with a guide as to where a fault might be occurring within a vehicle. DO NOT replace parts based only on DTCs without first consulting the vehicle's service manual for proper testing procedures for that particular system, circuit or component. 4 LAUNCH Professional 919X User Manual OBD II Diagnostic Trouble Codes consist of a five-digit alphanumeric code. · The 1st character is a letter (B, C, P or U). It identifies the main system where the fault occurred (Body, Chassis, Powertrain, or Network). · The 2nd character is a numeric digit (0 thru 3). It identifies the type of code (Generic or Manufacturer-Specific). Note: Generic DTCs are codes that are used by all vehicle manufacturers. The standards for generic DTCs, as well as their definitions, are set by the Society of Automotive Engineers (SAE). Manufacturer-Specific DTCs are codes that are controlled by the vehicle manufacturers. The Federal Government does not require vehicle manufacturers to go beyond the standardized generic DTCs in order to comply with the new OBD II emissions standards. However, manufacturers are free to expand beyond the standardized codes to make their systems easier to diagnose. · The 3rd character is a letter or a numeric digit (0 thru 9, A thru F). It identifies the specific system or sub-system where the problem is located. · The 4th and 5th characters are letters or numeric digits (0 thru 9, A thru F). They identify the section of the system that is malfunctioning. 5 LAUNCH Professional 919X User Manual P0201 - Injector circuit malfunction, Cylinder 1 1.5 Location of the Data Link Connector (DLC) The DLC (Data Link Connector or Diagnostic Link Connector) is typically a 16-pin connector where diagnostic code readers interface with the vehicle's on-board computer. It is usually located 12 inches from the center of the 6 LAUNCH Professional 919X User Manual instrument panel, under or around the driver's side for most vehicles. For some vehicles with special designs, the DLC location may vary. Refer to the following figure for location. A Opel, Volkswagen, Audi B Honda C Volkswagen D Opel, Volkswagen, Citroen E Changan Hyundai, Daewoo, Kia, Honda, Toyota, Nissan, Mitsubishi, F Renault, Opel, BMW, Mercedes-Benz, Mazda, Volkswagen, Audi, GM, Chrysler, Peugeot, Regal, Beijing Jeep, Citroen and other most popular models If the DLC cannot be found, refer to the vehicle's service manual for the location. 1.6 OBD II Monitors An important part of a vehicle's OBD II system is the Readiness Monitors, which are indicators used to find out if all of the emissions components have been evaluated by the OBD II system. They are running periodic tests on specific systems and components to ensure that they are performing within allowable limits. Monitor operation is either "Continuous" or "Non-Continuous," depending on the specific monitor. 7 LAUNCH Professional 919X User Manual 1.6.1 Continuous Monitors Some of the vehicle components or systems are continuously tested by the vehicle's OBD II system, while others are tested only under specific vehicle operating conditions. The continuously monitored components listed below are always ready: 1. Misfire Monitor This Monitor continuously checks for engine misfires. A misfire occurs when the air-fuel mixture in the cylinder does not ignite. The misfire Monitor uses changes in crankshaft speed to sense an engine misfire. When a cylinder misfires, it no longer contributes to the speed of the engine, and engine speed decreases each time the affected cylinder(s) misfire. The misfire Monitor is designed to sense engine speed fluctuations and determine from which cylinder(s) the misfire is coming, as well as how bad the misfire is. There are three types of engine misfires, Types 1, 2, and 3. · Type 1 and Type 3 misfires are two-trip monitor faults. If a fault is sensed on the first trip, the computer temporarily saves the fault in its memory as a Pending Code. The MIL is not commanded on at this time. If the fault is found again on the second trip, under similar conditions of engine speed, load and temperature, the computer commands the MIL "On," and the code is saved in its long term memory. · Type 2 misfires are the most severe type of misfire. When a Type 2 misfire is sensed on the first trip, the computer commands the MIL to light when the misfire is sensed. If the computer determines that a Type 2 misfire is severe, and may cause catalytic converter damage, it commands the MIL to "flash" once per second as soon as the misfire is sensed. When the misfire is no longer present, the MIL reverts to steady "On" condition. The Misfire Monitor is supported by both "spark ignition" vehicles and "compression ignition" vehicles. 2. Fuel System Monitor This Monitor uses a Fuel System Correction program, called Fuel Trim, inside the on-board computer. Fuel Trim is a set of positive and negative values that represent adding or subtracting fuel from the engine. This program is used to correct for a lean (too much air/not enough fuel) or rich (too much fuel/not enough air) air-fuel mixture. The program is designed to add or subtract fuel, as needed, up to a certain percent. If the correction needed is too large and exceeds the time and percent allowed by the program, a fault is indicated by the computer. 8 LAUNCH Professional 919X User Manual The Fuel System Monitor is supported by both "spark ignition" vehicles and "compression ignition" vehicles. The Fuel System Monitor may be a "One-Trip" or "Two-Trip" Monitor, depending on the severity of the problem. 3. Comprehensive Components Monitor (CCM) This Monitor continuously checks all inputs and outputs from sensors, actuators, switches and other devices that provide a signal to the computer. The Monitor checks for shorts, opens, out of range value, functionality and "rationality*." The CCM is supported by both "spark ignition" vehicles and "compression ignition" vehicles. The CCM may be either a "One-Trip" or a "Two-Trip" Monitor, depending on the component. 1.6.2 Non-Continuous Monitors "Non-continuous" Monitors perform and complete their testing once per trip. The "non-continuous" Monitors are: 1. O2 Sensor Monitor The Oxygen Sensor monitors how much oxygen is in the vehicle's exhaust. It generates a varying voltage of up to one volt, based on how much oxygen is in the exhaust gas, and sends the signal to the computer. The computer uses this signal to make corrections to the air/fuel mixture. If the exhaust gas has a large amount of oxygen (a lean air/fuel mixture), the oxygen sensor generates a "low" voltage signal. If the exhaust gas has very little oxygen (a rich mixture condition), the oxygen sensor generates a "high" voltage signal. A 450mV signal indicates the most efficient, and least polluting, air/fuel ratio of 14.7 parts of air to one part of fuel. The oxygen sensor must reach a temperature of at least 600-650°F, and the engine must reach normal operating temperature, for the computer to enter into closed-loop operation. The oxygen sensor only functions when the computer is in closed-loop. A properly operating oxygen sensor reacts quickly to any change in oxygen content in the exhaust stream. A faulty oxygen sensor reacts slowly, or its voltage signal is weak or missing. The Oxygen Sensor Monitor is supported by "spark ignition" vehicles only. The Oxygen Sensor Monitor is a "Two-Trip" monitor. If a fault is found on the first trip, the computer temporarily saves the fault in its memory as a Pending Code. The computer does not command the MIL on at this time. If the fault is sensed again on the second trip, the computer commands the MIL "On," and saves the code in its long-term memory. 9 LAUNCH Professional 919X User Manual 2. O2 Sensor Heater Monitor The Oxygen Sensor Heater Monitor tests the operation of the oxygen sensor's heater. There are two modes of operation on a computer-controlled vehicle: "open-loop" and "closed-loop." The vehicle operates in open-loop when the engine is cold, before it reaches normal operating temperature. The vehicle also goes to open-loop mode at other times, such as heavy load and full throttle conditions. When the vehicle is running in open-loop, the oxygen sensor signal is ignored by the computer for air/fuel mixture corrections. Engine efficiency during open-loop operation is very low, and results in the production of more vehicle emissions. Closed-loop operation is the best condition for both vehicle emissions and vehicle operation. When the vehicle is operating in closed-loop, the computer uses the oxygen sensor signal for air/fuel mixture corrections. In order for the computer to enter closed-loop operation, the oxygen sensor must reach a temperature of at least 600°F. The oxygen sensor heater helps the oxygen sensor reach and maintain its minimum operating temperature (600°F) more quickly, to bring the vehicle into closed-loop operation as soon as possible. The Oxygen Sensor Heater Monitor is supported by "spark ignition" vehicles only. The Oxygen Sensor Heater Monitor is a "Two-Trip" Monitor. If a fault is found on the first trip, the computer temporarily saves the fault in its memory as a Pending Code. The computer does not command the MIL on at this time. If the fault is sensed again on the second trip, the computer commands the MIL "On," and saves the code in its long-term memory. 3. Catalyst Monitor The catalytic converter is a device that is installed downstream of the exhaust manifold. It helps to oxidize (burn) the unburned fuel (hydrocarbons) and partially burned fuel (carbon monoxide) left over from the combustion process. To accomplish this, heat and catalyst materials inside the converter react with the exhaust gases to burn the remaining fuel. Some materials inside the catalytic converter also have the ability to store oxygen, and release it as needed to oxidize hydrocarbons and carbon monoxide. In the process, it reduces vehicle emissions by converting the polluting gases into carbon dioxide and water. The computer checks the efficiency of the catalytic converter by monitoring the oxygen sensors used by the system. One sensor is located before (upstream of) the converter; the other is located after (downstream of) the converter. If the catalytic converter loses its ability to store oxygen, the downstream sensor 10 LAUNCH Professional 919X User Manual signal voltage becomes almost the same as the upstream sensor signal. In this case, the monitor fails the test. The Catalyst Monitor is supported by "spark ignition" vehicles only. The Catalyst Monitor is a "Two-Trip" Monitor. If a fault is found on the first trip, the computer temporarily saves the fault in its memory as a Pending Code. The computer does not command the MIL on at this time. If the fault is sensed again on the second trip, the computer commands the MIL "On" and saves the code in its long-term memory. 4. Heated Catalyst Monitor Operation of the "heated" catalytic converter is similar to the catalytic converter. The main difference is that a heater is added to bring the catalytic converter to its operating temperature more quickly. This helps reduce emissions by reducing the converter's down time when the engine is cold. The Heated Catalyst Monitor performs the same diagnostic tests as the catalyst Monitor, and also tests the catalytic converter's heater for proper operation. The Heated Catalyst Monitor is supported by "spark ignition" vehicles only. This Monitor is also a "Two-Trip" Monitor. 5. EGR (Exhaust Gas Recirculation) System Monitor The Exhaust Gas Recirculation (EGR) system helps reduce the formation of Oxides of Nitrogen during combustion. Temperatures above 2500°F cause nitrogen and oxygen to combine and form Oxides of Nitrogen in the combustion chamber. To reduce the formation of Oxides of Nitrogen, combustion temperatures must be kept below 2500°F. The EGR system recirculates small amounts of exhaust gas back into the intake manifold, where it is mixed with the incoming air/fuel mixture. This reduces combustion temperatures by up to 500°F. The computer determines when, for how long, and how much exhaust gas is recirculated back to the intake manifold. The EGR Monitor performs EGR system function tests at preset times during vehicle operation. The EGR Monitor is supported by both "spark ignition" vehicles and "compression ignition" vehicles. The EGR Monitor is a "Two-Trip" Monitor. If a fault is found on the first trip, the computer temporarily saves the fault in its memory as a Pending Code. The computer does not command the MIL on at this time. If the fault is sensed again on the second trip, the computer commands the MIL "On," and saves the code in its long-term memory. 6. Evaporative System Monitor 11 LAUNCH Professional 919X User Manual OBD II vehicles are equipped with a fuel Evaporative system (EVAP) that helps prevent fuel vapors from evaporating into the air. The EVAP system carries fumes from the fuel tank to the engine where they are burned during combustion. The EVAP system may consist of a charcoal canister, fuel tank cap, purge solenoid, vent solenoid, flow monitor, leak detector and connecting tubes, lines and hoses. Fumes are carried from the fuel tank to the charcoal canister by hoses or tubes. The fumes are stored in the charcoal canister. The computer controls the flow of fuel vapors from the charcoal canister to the engine via a purge solenoid. The computer energizes or deenergizes the purge solenoid (depending on solenoid design). The purge solenoid opens a valve to allow engine vacuum to draw the fuel vapors from the canister into the engine where the vapors are burned. The EVAP Monitor checks for proper fuel vapor flow to the engine, and pressurizes the system to test for leaks. The computer runs this Monitor once per trip. The EVAP Monitor is supported by "spark ignition" vehicles only. The EVAP Monitor is a "Two-Trip" Monitor. If a fault is found on the first trip, the computer temporarily saves the fault in its memory as a Pending Code. The computer does not command the MIL on at this time. If the fault is sensed again on the second trip, the PCM commands the MIL "On," and saves the code in its longterm memory. 7. Secondary Air System Monitor When a cold engine is first started, it runs in open-loop mode. During openloop operation, the engine usually runs rich. A vehicle running rich wastes fuel and creates increased emissions, such as carbon monoxide and some hydrocarbons. A Secondary Air System injects air into the exhaust stream to aid catalytic converter operation: · It supplies the catalytic converter with the oxygen it needs to oxidize the carbon monoxide and hydrocarbons left over from the combustion process during engine warmup. · The extra oxygen injected into the exhaust stream also helps the catalytic converter reach operating temperature more quickly during warm-up periods. The catalytic converter must heat to operating temperature to work properly. The Secondary Air System Monitor checks for component integrity and system operation, and tests for faults in the system. The computer runs this Monitor once per trip. The Secondary Air System Monitor is a "Two-Trip" monitor. If a fault is found 12 LAUNCH Professional 919X User Manual on the first trip, the computer temporarily saves this fault in its memory as a Pending Code. The computer does not command the MIL on at this time. If the fault is sensed again on the second trip, the computer commands the MIL "On," and saves the code in its long-term memory. 1.7 DTCs and MIL Status When the vehicle's on-board computer detects a failure in an emissionsrelated component or system, the computer's internal diagnostic program assigns a diagnostic trouble code (DTC) that points to the system (and subsystem) where the fault was found. The diagnostic program saves the code in the computer's memory. It records a "Freeze Frame" of conditions present when the fault was found, and lights the Malfunction Indicator Lamp (MIL). Some faults require detection for two trips in a row before the MIL is turned on. Note: The "Malfunction Indicator Lamp" (MIL) is the accepted term used to describe the lamp on the dashboard that lights to warn the driver that an emissionsrelated fault has been found. Some manufacturers may still call this lamp a "Check Engine" or "Service Engine Soon" light. There are two types of DTCs used for emissions-related faults: Type "A" and Type "B." Type "A" codes are "One-Trip" codes; Type "B" DTCs are usually Two-Trip DTCs. When a Type "A" DTC is found on the First Trip, the following events take place: · The computer commands the MIL "On" when the failure is first found. · If the failure causes a severe misfire that may cause damage to the catalytic converter, the MIL "flashes" once per second. The MIL continues to flash as long as the condition exists. If the condition that caused the MIL to flash is no longer present, the MIL will light "steady" On. · A DTC is saved in the computer's memory for later retrieval. · A "Freeze Frame" of the conditions present in the engine or emissions system when the MIL was ordered "On" is saved in the computer's memory for later retrieval. This information shows fuel system status (closed loop or open loop), engine load, coolant temperature, fuel trim value, MAP vacuum, engine RPM and DTC priority. When a Type "B" DTC is found on the First Trip, the following events take place: · The computer sets a Pending DTC, but the MIL is not ordered "On." 13 LAUNCH Professional 919X User Manual "Freeze Frame" data may or may not be saved at this time depending on manufacturer. The Pending DTC is saved in the computer's memory for later retrieval. · If the failure is found on the second consecutive trip, the MIL is ordered "On." "Freeze Frame" data is saved in the computer's memory. · If the failure is not found on the second Trip, the Pending DTC is erased from the computer's memory. The MIL will stay lit for both Type "A" and Type "B" codes until one of the following conditions occurs: · If the conditions that caused the MIL to light are no longer present for the next three trips in a row, the computer automatically turns the MIL "Off" if no other emissions-related faults are present. However, the DTCs remain in the computer's memory as a history code for 40 warm-up cycles (80 warmup cycles for fuel and misfire faults). The DTCs are automatically erased if the fault that caused them to be set is not detected again during that period. · Misfire and fuel system faults require three trips with "similar conditions" before the MIL is turned "Off." These are trips where the engine load, RPM and temperature are similar to the conditions present when the fault was first found. Note: After the MIL has been turned off, DTCs and Freeze Frame data stay in the computer's memory. · Erasing the DTCs from the computer's memory can also turn off the MIL. If a Diagnostic Tool is used to erase the codes, Freeze Frame data will also be erased. 14 LAUNCH 2 Product Descriptions 2.1 Components & Controls Professional 919X User Manual 1.

If you are testing the battery under the circumstance of in-car inspection, tap [Next] to continue the start system test and charging health test. For more details on the start system test and charging health test, refer to Chapter 8.1.3 and Chapter 8.1.4. There are total 5 battery test conclusions, which are displayed at the end of the test report. 1. Good battery - Indicates that the battery is normal. 2. Replace battery - Indicates that the battery is aged or becomes rejected, or battery life cycle is nearly exhausted. In this case, battery voltage appears to be normal, but battery itself is not well, i.e. battery polarity board has been completely vulcanized or aged. Please replace battery immediately. 3. Good-recharge - Stands for low battery. The battery is good itself. 4. Charge-retest - It is better for a few batteries to be fully charged before testing in order to avoid judging in error under special conditions. 5. Bad cell - Indicates one of the battery cells is bad and cannot work normally, but for which one is bad, it can't be verified. In this case, battery voltage is generally lower than 11V, mainly resulting from internal circuitry damage, such as short circuit, open circuit, dummy weld etc. 8.1.3 Start System Test It is mainly to detect and analyze the starting motor, detect the actual starting current and starting voltage required by the starting motor, so as to judge whether the starting motor is normal or not. The abnormal starting motor may be caused by the following reasons: the lubrication system is faulty, causing the motor to start with the increase of load torque, the rotor of automobile starting motor sweeps the bore, resulting in the increase of self-friction of starting motor. 1. After connection is properly done, go to [BTS] and select [Start System Test]. 54 LAUNCH Professional 919X User Manual 2. Turn off all electrical components, including lights, radio and A/C etc. and stop the engine before test, tap [Confirm] to confirm. 3. Start the engine according to the prompts on the screen. After the start, the system will display the start voltage test result. 8.1.4 Charging Health Test This function mainly detects and analyzes the vehicle charging system, including generator, rectifier, rectifier diode, etc. Through this test, we can know that the output voltage of the generator, the rectifier diode, and the charging current is normal or not respectively. 1. After connection is properly done, go to [BTS] and select [Charging Health Test]. 2. Start the engine and start charging until the charging voltage and ripple are normal. 3. According to the on-screen prompts, press the accelerator and increase the engine speed to 2500rpm for 5 seconds. 4. Output the test result. 55 LAUNCH Professional 919X User Manual Notes: On-load voltage shown in the test result refers to the charging voltage when there is a load. It evaluates the on-load capacity of the generator. When different auto parts are opened, the load voltage will be generated. The on-load voltage will greatly vary depending on the auto parts being opened. 8.1.5 Report This function allows you to view, share and delete the test reports. 8.1.6 Precautions on battery test · The accuracy of battery voltage, charging voltage, start voltage is 0.01V in test results; CCA (Cold Cranking Amps) precision is 5CCA. Generally, charging voltage value is greater than starting voltage. · Starting voltage range: The value higher than 9.6V is normal, otherwise it is too low. Due to different situations, whether the starting voltage is higher or not does not mean the vehicles or batteries are faulty. · Generally, the voltage is lower than 11V for the bad cell battery, but it is possible that the battery is completely exhausted or has a serious low capacity. In this case, just recharge your battery. Bad cell always happens when the loads on a stopping vehicle are turned on for a long time. · It has no influence on test result in the event that engine's output voltage or engine revolution is not very stable. No matter whether the vehicle is accelerated or not, the output voltage only differs within 0.2V. · Pay more attention to connect the clip. The battery poles connect with conductor, which makes the clip has a poor connection when testing battery. A tolerance of dozens of CCA occurs if the clip is out of position, or oil, dust attaches on the pole. The gear and main body of clip should be 56 LAUNCH Professional 919X User Manual fully matched with battery poles. · Battery poles inside the vehicle are enveloped by connectors, which may produce some errors for test results. The tolerance results from the resistance of connectors. The greater the resistance value is, the greater the tolerance becomes. But generally, the tolerance does not affect the test conclusion. 8.2 TPMS This module allows you to configure the tablet as TPMS activation & diagnostic tool, which provides the ability to trigger TPMS sensor, program TPMS sensor, perform the relearning procedure.
