O: DTC B1892-Air Bag Tone Warn. Indicator Ckt Short to Gnd/Open

Normal Operation
The air bag Electronic Crash Sensor (ECS) module monitors its connection to the Generic Electronic Module (GEM) at Pin 13. This connection is used to signal a chime if the air bag indicator is inoperative and another SRS fault exists. If the ECS detects a short to ground or open on the connection to the GEM, it will store a Diagnostic Trouble Code (DTC) B1892 in memory.

Possible Causes
An air bag tone warning indicator circuit shorted to ground or open could be caused by:
- a short to ground or open on Circuit 1083 (LB/BK).
- a damaged or inoperative GEM.
