Output Components

Diagnose the output components for the proper response to PCM 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 evaporative emission (EVAP) system
• The electronic transmission controls
• The AC relay, if so equipped
• The vehicle speed sensor (VSS) output
• The malfunction indicator lamp (MIL) control
• The cruise control enable, if so equipped
