Pinpoint Test P: B1892 - Air Bag Tone Warning Indicator Circuit Short to Ground or Open

Normal Operation

The air bag Electronic Crash Sensor (ECS) module monitors its connection to the Generic Electronic Module (GEM) at C240a-8. 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 short to ground or open can be caused by:
- a short to ground or open on circuit 1083 (LB/BK).
- a damaged or inoperative GEM.
