1. Safety Precautions and Warnings To prevent personal injury or dama ge 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: Always perform automotive testing in a safe environment. Do not attempt to operate or observe the tool while driving a vehicle. Operating or observing the tool will cause driver distraction and could cause a fatal accident. Wear safety eye protection that meets ANSI standards.
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 (CARB) and implemented in 1988 to monitor some of the emission control components on vehicles. As technology evolved and the desire to improve the OnBoard Diagnostic system increased, a new generation of On-Board Diagnostic system was developed. This second generation of On-Board Diagnostic regulations is called "OBD II".

2.4 OBD II Readiness Monitors Readiness Monitors 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. currently, there are eleven OBD II Readiness Monitors (or l/M Monitors) defined by the U.S. Environmental Protection Agency (EPA).
2.5 OBD II Monitor Readiness Status OBD II systems must indicate whether or not the vehicle’s PCM’s monitoring has completed testing on each emission component. Components that have been OBD II tested will be reported as “OK”. The purpose of recording readiness status is to allow inspectors to determine if the vehicle’s OBDII system has tested all the emissions systems. This is handy to know before bringing vehicle to a state emissions testing facility.
intended to discourage vehicle operation. The vehicle onboard diagnostic system can not turn the MIL off until necessary repairs are completed or the condition no longer exists. DTC – Diagnostic Trouble Codes (DTC) these identify which section of the emission control system has malfunctioned. Enabling Criteria – Also termed Enabling Conditions. They are the vehicle-specific events of conditions that must occur within the engine before the various monitors will set, or run.
