Test N

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


Test N1-N2:






Test N3-N5:






Test N6:






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.
- an RCM internal concern.
- a worn or damaged connector shorting bar (harness side).
- a worn or damaged connector camming beam (component side).
