N2 - N4:

N6:

Normal Operation
The driver seat side impact sensor monitors the severity of a impact event. If the impact 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 seat side impact sensor for a signal that is out of the expected range. If the RCM detects an out-of-range signal from the driver seat 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 seat side impact sensor mounting failure fault can be caused by:
^ a driver seat side impact sensor internal fault.
^ a driver seat side impact sensor mounting failure.
^ an RCM internal concern.
