Test J1:






Test J2-J3:






Test J4-J5:






Normal Operation
The restraints control module (RCM) monitors the circuit to the passenger safety 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 safety 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 safety belt pretensioner.
- an RCM internal concern.
