Pinpoint Test AJ: LFC 18/DTC B1883 - Passenger Pretensioner Circuit Shorted to Ground

Normal Operation

The Restraints Control Module (RCM) monitors the circuit to the passenger belt pretensioner. When the RCM detects a circuit short to ground it will set Lamp Fault Code (LFC) 18 and Diagnostic Trouble Code (DTC) B1883.

Possible Causes

A short to ground on the passenger belt pretensioner circuit can be caused by:
- a short to ground on circuit 1081 (YE/RD).
- a short to ground on circuit 1082 (YE/BK).
- a short to ground on the passenger belt pretensioner.
- an RCM internal concern.
