Test V

PINPOINT TEST V: LFC 34/DTC B1934 - DRIVER AIR BAG CIRCUIT RESISTANCE LOW

Test V1-V3:

Test V3-V5:

Test V6:

Normal Operation
The Restraints Control Module (RCM) monitors the resistance of the driver air bag ignitor by measuring the resistance between pins 3 and 4. If the RCM 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 can be caused by:
^ a short in the clockspring windings.
^ a short in the wiring harness.
^ a low resistance in the driver air bag module.
^ a closed shorting bar.
^ a damaged camming beam.
^ an RCM internal concern.
