Normal Operation
The restraints control module (RCM) monitors the driver seat track position sensor circuits. If the RCM detects an 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 one 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.
- a faulty seat track position sensor.
- a faulted RCM.
