PINPOINT TEST 19: DTC C1948 - FRONT DRIVER'S SEAT TRACK POSITION SWITCH CIRCUIT RESISTANCE OUT OF RANGE
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 illuminate 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.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough Inspection and Verification before proceeding with the Pinpoint Test.
