Pcm Output Codes: Notes

WARNING: This page is about a different car, the 1995 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: All PCM OUTPUT tests are to be performed with key on, engine off.

PCM OUTPUTS selection provides ability to cycle PCM-controlled outputs. DIC display identifies solenoid or relay, and state PCM is commanding that device. HI indicates solenoid or relay is energized, and LO indicates solenoid or relay is de-energized. See Figure .
