Normal Operation
The restraints control module (RCM) monitors its connection to the instrument cluster at pin 26. This connection is used to signal a chime if the air bag indicator is inoperative and another SRS fault exists. If the RCM detects a short to ground or open on the connection to the instrument cluster, it will store a diagnostic trouble code (DTC) B1892 in memory.
Possible Causes
An air bag tone warning indicator circuit ground or open can be caused by:
- wiring, terminals or connectors.
- a faulted instrument cluster module.
- a faulted RCM.
