Page 2: Safety Precautions And Warnings
1. Safety Precautions and Warnings To prevent personal injury or damage to vehicles and/or the code reader, 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. Wear safety eye protection that meets ANSI standards. -
Page 3: General Information
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. -

Page 5: Obd Ii Readiness Monitors
2.4 OBD II Readiness 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. -

operated under specific conditions before the monitor is ready. These monitors are termed non-continuous monitors and are listed below: EGR System O2 Sensors Catalyst Evaporative System O2 Sensor Heater Secondary air Heated Catalyst A/C system 2.5 OBD II Monitor Readiness Status OBD II systems must indicate whether or not the vehicle’s PCM’s monitor system has completed testing on each component. -
Page 7: Obd Ii Definitions
2.6 OBD II Definitions Powertrain Control Module (PCM) -- OBD II terminology for the on-board computer that controls engine and drive train. Malfunction Indicator Light (MIL) -- Malfunction Indicator Light (Service Engine Soon, Check Engine) is a term used for the light on the instrument panel. - Page 8 Freeze Frame Data -- When an emissions related fault occurs, the OBD II system not only sets a code but also records a snapshot of the vehicle operating parameters to help in identifying 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.
