Driver Side Crash Sensor Mounting Failure
The driver side crash sensor monitors the severity of a crash event. If the crash event is severe enough, the sensor will signal the restraints control module (RCM) to deploy the driver side air bag.
The RCM monitors the two-wire current loop to the driver side crash sensor for a signal that is out of the expected range. If the RCM detects a signal from the driver side crash sensor, indicating a sensor mounting failure, it will store diagnostic trouble code (DTC) B2441 and flash a lamp fault code (LFC) 42 (or a higher priority code if one exists) on the air bag indicator.
A driver side crash sensor mounting failure fault can be caused by:
* damaged driver side crash sensor.
* corrosion or damage at the sensor mounting surface.
