Test X: LFC 49/DTC C1948 - Seat Track Position Sensor Circuit Resistance Out of Range

PINPOINT TEST X: LFC 49/DTC C1948 - SEAT TRACK POSITION SENSOR CIRCUIT RESISTANCE OUT OF RANGE

X1-X2:

X3-X5:

NOTE: Due to the seat track position sensor being a Hall-effect type sensor, this pinpoint test will be diagnosing a current out of range fault instead of the current DTC definition for a resistance out of range fault.

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 diagnostic trouble code (DTC) C1948 in memory and flash lamp fault code (LFC) 49 (or higher priority code if 1 exists) on the air bag indicator.

Possible Causes
A driver seat track position sensor circuit resistance out of range fault can be caused by:
- damaged wiring, terminals or connectors.
- a faulty driver seat track position sensor.
- RCM is faulted.
