Normal Operation
The connection between the instrument cluster and the RCM is used to signal a chime if the primary air bag indicator is inoperative and another SRS fault exists. The RCM monitors its connection to the instrument cluster module at C310a pin 23.

If the RCM detects an open or short to ground on the circuit to the cluster, it will store diagnostic trouble code (DTC) B1892 in memory and flash lamp fault code (LFC) 5-3 on the air bag indicator.

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