Input/Output Diagnostics: Outputs

NOTE: Maximum number of outputs for type-2 and type-3 BCMs is 3.

To test Body Control Module (BCM) outputs, ensure BCM is in diagnostic mode. See BODY CONTROL MODULE DIAGNOSTIC SYSTEM CHECK . Turn instrument panel dimmer switch to DOME position to begin first output test. To move to next test, cycle instrument panel dimmer switch from DOME position to off, then back to DOME position. BCM will sound chime the appropriate number of times to indicate which output test is entered. See BCM OUTPUT DIAGNOSTICS .
