Normal Operation
The Restraints Control Module (RCM) monitors the driver seat track position sensor circuits. If the RCM detects an open circuit or short to voltage, 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 seat track position sensor open circuit or short to voltage fault can be caused by:
^ Wiring, terminals, or connectors.
^ A faulty seat track position switch.
^ A faulty RCM.
