Test Notes

Normal Operation
The air bag Electronic Crash Sensor (ECS) module monitors the voltage of Circuits 1079 (LG/R) and 1080 (LG/BK) at Pins C200-24 and C200-25. If the ECS detects a short to ground on either of these pins, the ECS will store DTC B1876 in memory and flash LFC 17 (or higher priority code if one exists) on the air bag indicator.

Possible Causes
A driver belt and buckle assembly pretensioner circuit shorted to ground can be caused by:
- a short to ground on Circuit 1079 (LG/R).
- a short to ground on Circuit 1080 (LG/BK).
- a short to ground on the driver belt and buckle assembly pretensioner.
