 Safety Precautions and Warnings

To prevent personal injury or damage to vehicles and/or the scan tool, read this user guide first and observe at least the following safety precautions whenever working on a vehicle:

• Always perform automotive testing in a safe environment.
• Do not attempt to operate or watch the tool while driving a vehicle. Operating or watching the tool distracts the driver and could cause a fatal accident.
• Wear safety eye protection that meets ANSI standards.
• Keep clothing, hair, hands, tools, test equipment, etc. away from all moving or hot engine parts.
• Operate the vehicle in a well-ventilated work area: exhaust gases are poisonous.
• Put blocks in front of the drive wheels and never leave the vehicle unattended while running tests.
• Use extreme caution when working around the ignition coil, distributor cap, ignition wires and spark plugs. These components create hazardous voltages when the engine is running.
• Put the transmission in PARK (automatic transmission) or NEUTRAL (manual transmission) and make sure the parking brake is engaged.
• Keep a fire extinguisher suitable for gasoline, chemical and electrical fires nearby.
• Keep the scan tool dry and clean, free of oil, water and grease. When necessary, clean the outside of the scan tool with a mild detergent on a clean cloth.

General Information

 On-Board Diagnostics (OBD) II
The first generation of On-Board Diagnostics (called OBD I) was developed by the California Air Resources Board (CARB) and implemented in 1988 to monitor some of the emission control components on vehicles. As technology evolved and the desire to improve the on-board diagnostic system increased, a new generation of the on-board diagnostic system was developed. This second generation of on-board diagnostic regulations is called “OBD II”. The OBD II system is designed to monitor emission control systems and key engine components by performing either continuous or periodic tests of specific components and vehicle conditions. When a problem is detected, the OBD II system turns on a warning lamp (MIL) on the vehicle instrument panel to alert the driver, typically with the phrase “Check Engine” or “Service Engine Soon”. The system also stores important information about the detected malfunction so that a techniciancan accurately find and fix the problem. These three pieces of valuable information are:

1. whether the Malfunction Indicator Light (MIL) is commanded on or off;
2. which Diagnostic Trouble Codes (DTCs), if any, are stored;
3. the status of the readiness monitors.

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 guide you to where a fault might be occurring within the vehicle. OBD II Diagnostic Trouble Codes consist of a five-digit alphanumeric code. The first character, a letter, identifies which control system sets the code. The other four characters, all numbers, provide additional information on where the DTC originated and the operating conditions that caused it to be set. Below is an example that illustrates the structure of the digits:DTC exampleFigure 1: Structure of a diagnostic trouble code

Location of the Data Link Connector (DLC)
The DLC (Data Link Connector or Diagnostic Link Connector) is the standardized 16-pin connector through which diagnostic scan tools interface with the vehicle’s on-board computer. On most vehicles the DLC is located about 30 cm (12 inches) from the center of the instrument panel (dash), under or around the driver’s side. If the Data Link Connector is not located under the dashboard, a label should be there revealing its location. For some Asian and European vehicles, the DLC is located behind the ashtray and the ashtray must be removed to access the connector. If the DLC cannot be found, refer to the vehicle’s service manual for its location.Figure 2: Where the DLC can usually be found in the car interior

OBD II Readiness Monitors
Readiness monitors are indicators used to find out whether all of the emission components have been evaluated by the OBD II system. They run periodic tests on specific systems and components to ensure that they are performing within allowable limits.Currently, there are eleven OBD II readiness monitors (or I/M monitors) defined by the U.S. Environmental Protection Agency (EPA). Not all monitors are supported by all vehicles, and the exact number of monitors in any vehicle depends on the motor vehicle manufacturer’s emissions control strategy. 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
2. Fuel system
3. Comprehensive components (CCM)

Once the vehicle is running, the OBD II system continuously checks the abovecomponents, monitors key engine sensors, watches for engine misfire and monitors fuel demands.

Non-continuous monitors – Unlike the continuous monitors, many emission and engine system components require the vehicle to be operated under specific conditions before the monitor is ready. These monitors are termed non-continuous monitors and are listed below:

1. EGR system – exhaust gas recirculation for reducing emissions.
2. O2 sensors – monitor and adjust the air/fuel mixture.
3. Catalyst – reduces exhaust emissions.
4. Evaporative system – monitors the integrity of the fuel tank system.
5. O2 sensor heater – brings the O2 sensor to the correct operating temperature.
6. Secondary air – reduces exhaust emissions.
7. Heated catalyst – brings the catalyst to the correct operating temperature.
8. A/C system – monitors the system for refrigerant leaks.

OBD II Monitor Readiness Status
OBD II systems must indicate whether or not the vehicle’s PCM monitoring system has completed testing on each emission component. Components that have been tested will be reported as “OK”. The purpose of recording readiness status is to allow inspectors to determine whether the vehicle’s OBD II system has tested all the emission systems. This is handy to know before taking the vehicle to an emissions testing station.The powertrain control module (PCM) sets a monitor to “OK” after an appropriate drive cycle has been performed. The drive cycle that enables a monitor and sets its readiness code to “OK” varies for each individual monitor. Once a monitor is set to “OK”, it remains in this state. A number of factors, including erasing diagnostic trouble codes (DTCs) with a code reader or disconnecting the battery, can result in readiness monitors being set to “INC” (incomplete). Since the three continuous monitors are evaluated constantly, they will be reported as “OK” all of the time. As long as there are no DTCs stored in memory, the vehicle is running in accordance with the OBD II guidelines. If testing of a particular supported non-continuous monitor has not been completed, the monitor status will be reported as “INC” (incomplete).For the OBD monitor system to become ready, the vehicle should be driven under a variety of normal operating conditions. These may include a mix of highway driving and stop-and-go city driving, and at least one period in which the vehicle stays switched off overnight. For specific information on getting your vehicle’s OBD monitor system ready, please consult your vehicle owner’s manual.

OBD II Definitions
Powertrain Control Module (PCM)The OBD II term for the on-board computer that controls the engine and the drive train. Malfunction Indicator Light (MIL)The Malfunction Indicator Light (Service Engine Soon, Check Engine) is the term used for the light on the instrument panel. It alerts the driver and/or the repair technician that there is a problem with one or more of the vehicle’s systems which may cause emissions to exceed federal standards. If the MIL illuminates with a steady light, a problem has been detected and the vehicle should be serviced as soon as possible. Under certain conditions, the dashboard light will blink or flash. This indicates a severe problem, and the flashing is intended to discourage vehicle operation. The vehicle’s on-board diagnostic system cannot turn the MIL off until the necessary repairs are completed or the condition no longer exists.

• DTC
  Diagnostic Trouble Codes identify which section of the emission control system has malfunctioned.
  Enabling criteria
  Also termed enabling conditions. These are the vehicle-specific 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.
• OBD II drive cycle
  A specific mode of vehicle operation that provides the 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 on-board diagnostics. Some form of 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 the drive cycle of a specific vehicle, consult the vehicle’s owner’s manual.
• Freeze frame data
  When an emission-related fault occurs, the OBD II system not only sets a code but also records a snapshot of the vehicle operating parameters to help identify the problem. This set of values is referred to as freeze frame data and may include important engine parameters such as engine RPM, vehicle speed, air flow, engine load, fuel pressure, fuel trim value, engine coolant temperature, ignition timing advance or closed-loop status.
