Test P: The Safety Belt Warning Indicator Is Never/Always On

PINPOINT TEST P: THE SAFETY BELT WARNING INDICATOR IS NEVER/ALWAYS ON

Normal Operation
The safety belt warning indicator informs the driver that his/her safety belt and/or the front passengers safety belt is unbuckled. The first 65 seconds after the ignition switch transitions from OFF or ACC to RUN or START, the safety belt warning indicator and the associated chime are used as a reminder to the driver that the front row safety belts are not buckled. In this first 65 seconds the indicator illuminates when the driver and/or front passenger safety belt is unbuckled (with a person in the seat) and turns off whenever the safety belt(s) in the occupied front row seat(s) is buckled. The indicator illuminates again if a safety belt is unbuckled after both are buckled and the 65 seconds has not yet expired. After 65 seconds, the indicator turns off regardless of the front row safety belts status.

The safety belt switch is hardwired to the restraints control module (RCM). The instrument cluster (IC) receives the safety belt switch status from the RCM through circuit 1083 (LB/PK). When the safety belt is unfastened, the RCM signals the instrument cluster (IC) to illuminate the safety belt warning indicator. A Belt-Minder(R) chime that is operating correctly indicates the RCM is monitoring and transmitting the correct operation of the safety belt status to the instrument cluster (IC).

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- RCM
- Instrument cluster (IC)
