PINPOINT TEST U: LFC 49/DTC C1947 - DRIVER SEAT TRACK POSITION SENSOR CIRCUIT SHORT TO GROUND


U1-U3:






U3-U6:






Normal Operation
The seat track position sensor informs the restraints control module (RCM) of the driver seat position.

The RCM monitors the driver seat track position sensor circuits. If the RCM detects a short to ground, it will store diagnostic trouble code (DTC) C1947 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 short to ground fault can be caused by:
- wiring, terminals or connectors.
- a faulty driver seat track position sensor.
- a faulted RCM.
