Engine Control Module: Initial Inspection and Diagnostic Overview
Outputs
The PCM outputs option provides the ability to cycle PCM controlled outputs. The DIC display identifies the solenoid or relay, and the state that the
PCM is commanding that device. HI indicates that the solenoid or relay is de-energized, and LO indicates that the solenoid or relay is energized. The
PCM outputs tests can only be done at key ON engine OFF
