E5 - E6:

Normal Operation
The Restraints Control Module (RCM) monitors its connection to the Generic Electronic Module (GEM) at C310a pin 22, circuit 1083 (LB/BK). 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 on the connection to the GEM, it will store Diagnostic Trouble Code (DTC) B1892 in memory. The RCM will also 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:
^ a short to ground or open on circuit 1083 (LB/BK).
^ GEM is inoperative.
^ RCM is faulted.
