Normal Operation
The restraints control module (RCM) monitors the circuit to the driver seat belt buckle 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 driver pretensioner circuit short to battery or ignition 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 pretensioner.
- an RCM internal concern.
