Normal Operation
The Restraints Control Module (RCM) monitors the circuit to the driver belt pretensioner. When the RCM detects a circuit short to battery or ignition it will set Lamp Fault Code (LFC) 17 and Diagnostic Test Code (DTC) B1878.

Possible Causes
A short to battery or ignition on the driver belt pretensioner circuit can be caused by:
^ a short to battery or ignition on circuit 1079 (LG/RD).
^ a short to battery or ignition on circuit 1080 (LG/BK).
^ a short to battery or ignition on the driver belt pretensioner.
^ an RCM internal concern.
