Test G: The Safety Belt Warning Indicator Is Inoperative (Chime Is Operative)/Does Not Operate Correctly

PINPOINT TEST G: THE SAFETY BELT WARNING INDICATOR IS INOPERATIVE (CHIME IS OPERATIVE)/DOES NOT OPERATE CORRECTLY

Normal Operation
The safety belt switch is hardwired to the restraints control module (RCM). The RCM sends a signal on circuit 1083 (LB/BK) to the lighting control module (LCM) when the safety belt is fastened or unfastened, communicating the safety belt switch status. The LCM sends the safety belt switch status to the instrument cluster (IC) over the standard corporate protocol (SCP) communication network, to illuminate the safety belt warning indicator.

This pinpoint test is intended to diagnose the following:
- LCM
- Instrument cluster (IC)
