Normal Operation
The Restraints Control Module (RCM) monitors its connection to the lighting control module at C310b pin 11. 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 lighting control module, 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:
^ Wiring, terminals, or connectors.
^ lighting control module is faulted.
^ RCM is faulted.
