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 30S-JA34 (RD/BK).
- a short to ground on circuit 31S-JA34 (BK/RD).
- a short to ground on the passenger belt pretensioner.
- a faulted RCM.
