PINPOINT TEST G: LFC 17/DTC B1879 - DRIVER PRETENSIONER CIRCUIT SHORTED TO GROUND


Test G1:






Test G2-G3:






Test G4-G5:






Normal Operation
The restraints control module (RCM) monitors the circuit to the driver safety belt pretensioner. When the RCM detects a circuit short to ground it will set lamp fault code (LFC) 17 and diagnostic test code (DTC) B1879.

Possible Causes
A short to ground on the driver safety belt pretensioner circuit can be caused by:
- a short to ground on circuit 1079 (LG/RD)
- a short to ground on circuit 1080 (LG/BK).
- a short to ground on the driver safety belt pretensioner.
- an RCM internal concern.
