Test P: LFC 42/DTC B2441 -Driver Side Impact Sensor Mounting Failure

P1:

P2:

P3 - P4:

P5 - P6:

Normal Operation
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

Possible Causes
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.
