PINPOINT TEST L: LFC 35/DTC B1888 - PASSENGER AIR BAG CIRCUIT LOW RESISTANCE

Test L1-L3:

Test L3-L6:

Normal Operation

WARNING: DO NOT ATTEMPT A DIRECT RESISTANCE MEASUREMENT OF THE AIR BAG MODULE. A DIRECT RESISTANCE MEASUREMENT OF THE AIR BAG MODULE CAN CAUSE AIR BAG DEPLOYMENT, WHICH CAN RESULT IN PERSONAL INJURY. FOLLOW THE DIAGNOSTIC PROCEDURE TO DETERMINE IF THE AIR BAG MODULE RESISTANCE IS LOWER THAN NORMAL.

The air bag Electronic Crash Sensor (ECS) monitors the resistance of the passenger air bag ignitor by measuring the resistance between Pins C2209-14 and C2209-28. If the ECS detects low resistance, the ECS will store DTC B1888 in memory and flash LFC 35 (or higher priority code if one exists) on the air bag indicator.

Possible Causes
^ Damaged shorting bar on the ECS or passenger air bag module connectors.
^ A shorted condition in the wiring harness.
^ A shorted condition in the passenger air bag module.
