Test S: LFC 19/DTC B1936 - Driver Air Bag Circuit Shorted to Ground

PINPOINT TEST S: LFC 19/DTC B1936 DRIVER AIR BAG CIRCUIT SHORTED TO GROUND

S1-S3:

S3-S5:

S6-S7:

Normal Operation
The restraints control module (RCM) checks for driver air bag circuit shorts to ground by monitoring the voltage of circuits 614 (GY/OG) and 615 (GY/WH) at pins 1 and 2. If the RCM detects a short to ground on either of these pins, it will store a diagnostic trouble code (DTC) B1936 in memory and flash lamp fault code (LFC) 19 (or higher priority code if one exists) on the air bag indicator.

Possible Causes
A driver air bag circuit short to ground could be caused by:
- faulted wiring, terminals, or connectors.
- faulted clockspring
- a faulted driver air bag module.
- a faulted RCM.
