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 30S-JA33 (RD/BU).
- a short to battery or ignition on circuit 31S-JA33 (BK/BU).
- a faulted RCM.
