Test U: LFC 49 DTC C1948 - Front Driver's Seat Track Position Switch Circuit Resistance Out of Range

PINPOINT TEST U: LFC 49 DTC C1948 - FRONT DRIVER'S SEAT TRACK POSITION SWITCH CIRCUIT RESISTANCE OUT OF RANGE

Normal Operation
The restraints control module (RCM) monitors the driver seat track position sensor circuits. If the RCM detects a current out of range condition, it will store DTC C1948 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.
