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 Test 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.
