P5 - P6:

Normal Operation
The driver side impact 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 impact sensor for a signal that is out of the expected range. If the RCM detects a signal from the driver side impact 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.

Possible Causes
A driver side impact sensor mounting failure fault can be caused by:
^ damaged driver side impact sensor.
^ corrosion or damage at the sensor mounting surface.
