LAUNCH Creader Elite V2.0 OBD2 Scanner User Manual

1. Introduction

1.1 Product Overview

The LAUNCH Creader Elite V2.0 is an all-in-one, cost-effective car diagnostic scanner designed for comprehensive vehicle diagnostics. It offers full system scans, bi-directional control, advanced ECU coding, and a wide range of reset services. This tool is equipped with advanced software and hardware to provide deeper, faster, and more complete diagnostic services.

1.2 Vehicle Coverage

This diagnostic device is specifically designed to work with all OBD II compliant vehicles, including Controller Area Network (CAN). EPA requires all 1996 and newer passenger cars and light trucks sold in the United States to be OBD II compliant, which includes all American, Asian, and European vehicles.

A small number of 1994 and 1995 gasoline vehicles are OBD II compliant. To check if a vehicle is 1994 or 1995 OBD II compliant, check the following:

1. Vehicle Emission Control Information (VECI) Label: This label is usually located under the hood or on the radiator of most vehicles. If the vehicle is OBD II compliant, the label will state "OBD II Certified."
2. Data Link Connector (DLC): Regulations require all OBD II compliant vehicles to 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 vehicles with a Vehicle Emission Control Information label stating "OBD II Certified" are OBD II compliant.

1.3 OBD II System Overview

The OBD II system is designed to monitor emission control systems and critical engine components by performing continuous or periodic tests of specific components and vehicle conditions, providing three valuable pieces of information:

• Whether the Malfunction Indicator Lamp (MIL) is on or off.
• Which Diagnostic Trouble Codes (DTCs) are stored, if any.
• Status of the readiness monitor.

1.4 OBD II Definitions

• EOBD: European On-Board Diagnostics. Essentially the same as OBD II, with the same Data Link Connector and communication protocols.
• Communication Protocols: Enables communication between various systems and sensors in a vehicle. Currently, there are five protocols: CAN-Bus, J1850 VPW, ISO 9141-2, J1850 PWM, ISO 14230 KWP.
• PCM (Powertrain Control Module): The PCM is the term accepted by OBD II for the vehicle's "on-board computer." In addition to controlling engine management and emission systems, the PCM is also involved in controlling powertrain operation (transmission). Most PCMs can also communicate with other computers in the vehicle (ABS, steering, body, etc.).
• DLC (Data Link Connector): The 16-pin connector on the vehicle that enables communication between the computer system and the diagnostic device.
• MIL (Malfunction Indicator Lamp): The "Check Engine" warning light on the vehicle that illuminates when a DTC is stored.
• DTC (Diagnostic Trouble Code): A code stored in the computer system's memory that helps identify the fault condition causing the MIL to activate.
• Freeze Frame Data: Operating conditions stored when a DTC is set.
• PID (Parameter Identification Data): Data returned by the vehicle's control modules to the diagnostic device.
• Monitors: "Diagnostic routines" programmed into the PCM. The PCM uses these programs to perform diagnostic tests and monitor the operation of emission-related components or systems to ensure they function correctly and within manufacturer specifications.
• Enabling Criteria: Also called enabling conditions. These are vehicle-specific events or conditions that must occur within the engine before the various monitors are set or run. Some monitors require the vehicle to follow a prescribed "drive cycle" routine as part of the enabling criteria. Drive cycles vary between vehicles and for each monitor in a given vehicle. Refer to the vehicle's workshop manual for specific enabling procedures.
• Drive Cycle: A drive for a specific monitor requires the vehicle to be driven in such a way that all necessary "enabling criteria" are met for the monitor to run and complete its diagnostic tests. The "drive cycle" for a specific monitor begins when the ignition key is turned to "ON." It is successfully completed when all "enabling criteria" for the monitor's operation and completion of its diagnostic tests are met, when the ignition key is turned to "OFF." Since each of the fifteen monitors is designed to perform diagnostics and tests on a different part of the engine or emission system, the "drive cycle" required for each individual monitor to run and complete is different.
• Driving Cycle: A specific vehicle operating mode that provides the conditions necessary to set all applicable readiness monitors to the "Ready" state. The purpose of completing an OBD II driving cycle is to force the vehicle to perform its on-board diagnostics. A type of driving cycle must be performed after DTCs have been cleared from the PCM's memory or the battery has been disconnected. By completing a vehicle's full driving cycle, the readiness monitors are "set" so that future faults can be detected. Driving cycles vary depending on the vehicle and the monitor that needs to be reset. Information on vehicle-specific driving cycles can be found in the workshop manual.
• Warm-up Cycle: Vehicle operation after an engine shutdown period during which the engine temperature rises by at least 22°C (40°F) from the temperature before starting and reaches at least 70°C (160°F). The PCM uses warm-up cycles as a counter to automatically clear a specific code and associated data from its memory. If no faults related to the original problem are detected within a certain number of warm-up cycles, the code is automatically cleared.
• FT (Fuel Trim): Feedback adjustments to the basic fuel plan. Short-term fuel trim refers to dynamic or immediate adjustments. Long-term fuel trim refers to much more gradual adjustments to the fuel calibration plan than short-term trim adjustments. These long-term adjustments compensate for vehicle differences and gradual changes that occur over time.

1.5 Diagnostic Trouble Codes (DTCs)

OBD II Diagnostic Trouble Codes are codes stored by the on-board computer's diagnostic system in response to a problem detected in the vehicle. These codes identify a specific problem area and are intended to give you an indication of where a fault might be occurring in a vehicle. OBD II Diagnostic Trouble Codes consist of a 5-digit alphanumeric code. The first character, a letter, identifies which control system set the code. The second character, a number, 0-3; the other three characters, a hexadecimal character, 0-9 or A-F, provide additional information about where the DTC originated and what operating conditions set it. Below is an example illustrating the structure of the digits:

Example of a Diagnostic Trouble Code (DTC) structure, showing system, code type, and sub-system identification.

1.6 Data Link Connector (DLC) Location

The DLC (Data Link Connector) is typically a 16-pin connector used to connect the diagnostic code reader to the vehicle's on-board computer. It is usually located 12 inches from the center of the instrument panel, under or around the driver's side in most vehicles. In some vehicles with special designs, the DLC's location may vary.

Diagram showing common DLC locations in various vehicle models.

If the DLC cannot be found, refer to the vehicle's workshop manual for its position.
