Test Notes

Normal Operation
The air bag Electronic Crash Sensor (ECS) module monitors the voltage of Circuits 614 (GY/O) and 615 (GY/W) at Pins C200-1 and C200-15. If the ECS detects a short to ground or battery on either of these pins the ECS will store DTC B1915 in memory and flash LFC 15 (or higher priority code if one exists) on the air bag indicator.

Possible Causes
A driver air bag circuit failure can be caused by:
- a short to ground or battery on Circuit 614 (GY/O).
- a short to ground or battery on Circuit 615 (GY/W).
- a short to ground or battery on the air bag sliding contact.
- a short to ground or battery on the driver air bag module.
