Test K: LFC 34/DTC B1934 - Driver Air Bag Circuit Resistance Low

K1:

K2 - K3:

K4 - K6:

Normal Operation
The air bag Electronic Crash Sensor (ECS) module monitors the resistance of the driver air bag ignitor by measuring the resistance between pins 1 and 15. If the ECS detects low resistance between these pins, it will store a Diagnostic Trouble Code (DTC) B1934 in memory and flash a Lamp Fault Code (LFC) 34 (or higher priority code if one exists) on the air bag indicator.

Possible Causes
Driver air bag low resistance could be caused by:
^ a short in the clockspring windings.
^ a short in the wiring harness.
^ a low resistance in the driver air bag module.
