Test W: LFC 49/DTC C1948 - Front Driver's Seat Track Position Switch Circuit Resistance Out Of Range

PINPOINT TEST W: LFC 49/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 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 current out of range condition, it will store DTC C1948 in memory and flash LFC 49 (or higher priority code if one exists) on the air bag warning indicator.

- DTC C1948 Front Driver's Seat Track Position Switch Circuit Resistance Out of Range - If the RCM detects a current out of range between forward and rearward on the driver seat track position switch, it will set this DTC.

This pinpoint test is intended to diagnose the following:
- Seat track position sensor
- RCM
