Test AA4:

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 a current out of range condition, it will store diagnostic trouble code (DTC) C1948 in memory and, depending on the fault, flash a lamp fault code (LFC) on the air bag indicator.

Possible Causes
A seat track sensor circuit resistance out of range fault can be caused by:
- a faulty driver seat track position sensor.
- a faulted RCM.
