  • Page 4: 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: Location Of The Data Link Connector (Dlc)

    2.3 Location of the Data Link Connector (DLC) The DLC (Data Link Connector or Diagnostic Link Connector) 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.

  • Page 6: 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.

  • Page 7: Obd Ii Monitor Readiness Status

    monitors are termed non-continuous monitors. For different ignition type engines, the available monitors are different too. The following monitors are to be used for spark ignition engines only: EGR System O2 Sensors Catalyst Evaporative System O2 Sensor Heater Secondary Air Heated Catalyst The following monitors are to be used for compression ignition engines only:...

  • Page 8: Obd Ii Definitions

    including erasing of diagnostic trouble codes (DTCs) with a scan tool or a disconnected battery, can result in Readiness Monitors being set to “Not Ready”. Since the three continuous monitors are constantly evaluating, they will be reported as “Ready” all of the time. If testing of a particular supported non-continuous monitor has not been completed, the monitor status will be reported as “Not Complete”...
