Output Components

Output components are diagnosed for proper response 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 circuit:

• Idle Air Control (IAC) Motor.
• Control module controlled EVAP Canister Purge Valve.
• A/C relays.
• Cooling fan relay.
• VSS output.
• MIL control.
• Cruise control inhibit.
