Lamp Fault Codes (LFCs)







The lamp fault code (LFC) indicates the specific fault associated with diagnostic trouble code (DTC) C1946.

Normal Operation
The seat track position sensor informs the RCM of the drivers seat position.

The restraints control module (RCM) monitors the driver seat track position sensor circuits. If the RCM detects an open circuit fault, it will store diagnostic trouble code (DTC) C1946 in memory and flash a lamp fault code on the air bag indicator.

Possible Causes
A driver seat track position sensor open circuit fault can be caused by:
- faulted wiring, terminals or connectors.
- a faulted driver seat track position sensor.
- a faulted RCM.
