Pinpoint Test AI: LFC 18/DTC B1882 - Passenger Pretensioner Circuit Shorted to Battery or Ignition

Normal Operation

The Restraints Control Module (RCM) monitors the circuit to the passenger belt and buckle assembly pretensioner. When the RCM detects a circuit short to battery or ignition it will set Lamp Fault Code (LFC) 18 and Diagnostic Trouble Code (DTC) 1882.

Possible Causes

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