PINPOINT TEST D: LFC 16/DTC B1920 - PASSENGER AIR BAG CIRCUIT FAULT

Test D1-D3:

Test D4-D7:

Normal Operation
The air bag Electronic Crash Sensor (ECS) module monitors the voltage of Circuits 607 (LB/O) and 616 (PK/BK) at Pins C2209-14 and C2209-28. If the ECS detects a short to ground or battery on either of these pins, the ECS will store DTC B1920 in memory and flash LFC 16 (or higher priority code if one exists) on the air bag indicator.

Possible Causes
A passenger air bag circuit fault can be caused by:
^ a short to ground or battery on Circuit 607 (LB/O).
^ a short to ground or battery on Circuit 616 (PK/BK).
^ a short to ground or battery on the passenger air bag module.
