Test Notes

Normal Operation
The air bag Electronic Crash Sensor (ECS) module monitors the voltage of Circuits 1081 (Y/R) and 1082 (Y/BK) at Pins C1-26 and C1-27. If the ECS detects a short to ground on either of these pins, the ECS will store DTC B1880 in memory and flash LFC 18 (or higher priority code if one exists) on the air bag indicator.

Possible Causes
A passenger belt and buckle assembly pretensioner circuit shorted to ground can be caused by:
- a short to ground on Circuit 1081 (Y/R).
- a short to ground on Circuit 1082 (Y/BK).
- a short to ground on the passenger belt and buckle assembly pretensioner.
