Normal Operation
The restraints control module (RCM) monitors its connection to the instrument cluster module at C310a pin 22. 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 cluster, it will store diagnostic trouble code (DTC) B1892 in memory and flash lamp fault code (LFC) 53 (or a higher priority code if one exists) on the air bag indicator.

Possible Causes
An air bag tone warning indicator circuit short to ground or open can be caused by:
- damaged wiring, terminals, or connectors.
- a damaged or inoperative instrument cluster module.
- a faulted RCM.
