Normal Operation
The driver seat side impact sensor monitors the severity of a crash event. If the crash is severe enough, the sensor will signal the Restraints Control Module (RCM) to deploy the driver seat 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 fault, 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 fault can be caused by:
^ a driver seat side impact sensor internal fault.
^ a driver seat side impact sensor mounting fault.
^ RCM is faulted.
