California Air Resources Board OBD II Comprehensive Component Monitoring List of Components Intended to Illuminate MIL

The output components respond to control module commands. Components where functional monitoring is not feasible will be monitored for circuit continuity and out-of-range values if applicable.

Output components to be monitored include, but are not limited to the following circuits:
^ The Idle Air Control (IAC) motor
^ The control module controlled EVAP canister purge valve
^ The electronic transmission controls
^ The A/C relay
^ The cooling fan relay
^ The VSS output
^ The MIL control
^ The cruise control inhibit
^ Transmission shift solenoid B
^ Transmission 3/2 shift solenoid
^ Ignition Control (IC) system
^ Idle Air Control (IAC) coil
^ Evaporative emission purge vacuum switch
^ Evaporative Emission Canister Purge (EVAP canister purge)
