Normal Operation
The restraints control module (RCM) monitors the driver seat track position sensor circuits. If the RCM detects a open or short to battery, it will store diagnostic trouble code (DTC) C1981 in memory and flash lamp fault code (LFC) 49 (or higher priority code if 1 exists) on the air bag indicator.

Possible Causes
A driver seat track position sensor open circuit or short to battery fault can be caused by:
- damaged wiring, terminals or connectors.
- RCM is faulted.
