The restraints control module (RCM) monitors the driver seat track position sensor circuits. If the RCM detects an open circuit or a short to battery on the driver seat track position sensor, it will store DTC C1981 in memory and send a message to the instrument cluster module to flash a LFC 49 (or higher priority code if one exists) on the air bag warning indicator.

NOTE: When monitoring fault and/or resistance PIDs with the scan tool, it may take up to 2 seconds for the scan tool display to update.
