1. Safety Precautions And Warnings To prevent personal injury or damage to vehicles and/ or the Scan Tool, read this instruction manual first and observe the following safety precautions, at a minimum, whenever working on a vehicle: 1. Always perform automotive testing in a safe environment. 2. Wear safety eye protection that meets ANSI standards. 3. Keep clothing, hair, hands, tools, test equipment, etc. away from all moving or hot engine parts. 4.
2. General Information 2.1 On-Board Diagnostics (OBD) II The first generation of On-Board Diagnostics (called OBD I) was developed by the California Air Resources Board (ARB) 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 On-Board Diagnostic system was developed. This second generation of OnBoard Diagnostic regulations is called OBD II.
2.2 Diagnostic Trouble Codes (DTCs) OBD II DTCs are codes that are stored by the vehicles' OnBoard 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. OBD II DTCs consists of a five-digit alphanumeric code. The first character, a letter, identifies which control system sets the code.
2.3 Location of the Data Link Connector (DLC) The DLC is the standardized 16-cavity connector where diagnostic Scan Tools interface with the vehicle's on-board computer. The DLC is usually located 12 inches from the center of the instrument panel (dash), under or around the driver's side for most vehicles. If the DLC is not located under dashboard, a label should be there indicating its location.
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 is continuously checking the above components, monitoring key engine sensors, watching for engine misfire, and monitoring fuel demands.
The Power-Train Control Module (PCM) sets a monitor to “Ready” or “Complete” after an appropriate drive cycle has been performed. The drive cycle that enables a monitor and sets readiness codes to “Ready” varies for each individual monitor. Once a monitor is set as “Ready” or “Complete”, it will remain in this state. A number of factors, including erasing of DTCs with a Scan Tool or a disconnected battery, can result in Readiness Monitors being set to “Not Ready”.
The vehicle's On-Board Diagnostic system cannot turn the MIL off until necessary repairs are completed or the condition no longer exists. DTC -- Diagnostic Trouble Code that identifies which section of the emission control system has malfunctioned. OBD II 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.
