Output Components

Diagnose the output components for the proper response to the PCM commands. Components where functional monitoring is not feasible will be monitored for circuit continuity and for out-of-range values if applicable.

The output components to be monitored include, but are not limited to, the following circuits:

• The idle air control (IAC) motor
• The EVAP system
• The electronic transmission controls
• The A/C relay
• The cooling fan relay
• The VSS output
• The MIL control
• The cruise control inhibit, if the vehicle has this equipment
