Test P: The Air Bag Warning Indicator Is Never/Always On

PINPOINT TEST P: THE AIR BAG WARNING INDICATOR IS NEVER/ALWAYS ON

Normal Operation
The air bag warning indicator is used to provide a status of the supplemental restraint system. The instrument cluster (IC) receives a message from the restraints control module (RCM) over the high speed controller area network (HS-CAN). If an air bag system concern is detected, a DTC is logged and the RCM sends a message to the instrument cluster (IC) to illuminate the air bag warning indicator. If the instrument cluster (IC) does not receive the restraints control command, the instrument cluster (IC) illuminates the air bag warning indicator.

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