Test P6:
Normal Operation
The Restraints Control Module (RCM) monitors its connection to the Instrument Cluster at C220b pin 10. 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 short to ground or open can be caused by:
^ a short to ground or open on circuit 1083 (LB/BK).
^ a damaged or inoperative instrument cluster.
^ an RCM internal concern.
