Output Components
WARNING: This page is about a different car, the 2005 Chevrolet Optra5 and 2005 Chevrolet Optra. However, it is still accessible from the selected car via links, so may be relevant.
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 circuits:
- Idle air control (IAC) motor or an idle speed (ISC) control
- Control module controlled evaporative emission (EVAP) canister purge valve
- A/C relays
- Cooling fan relay
- Vehicle speed sensor (VSS) output
- Malfunction indicator lamp (MIL) control
