Test P5-P6:

Normal Operation
The restraints control module (RCM) monitors its connection to the instrument cluster at C310a at pin 26. 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 8-JA13 (WH/BK).
- a damaged or inoperative instrument cluster.
- a faulted RCM.
