Normal Operation
The passenger 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 passenger seat side air bag.

The RCM monitors the two-wire current loop to the passenger 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 passenger seat side impact sensor, indicating a fault, it will store Diagnostic Trouble Code (DTC) B2445 and flash a Lamp Fault Code (LFC) 49 (or a higher priority code if one exists) on the air bag indicator.

Possible Causes
A passenger seat side impact sensor fault can be caused by:
^ damaged passenger seat side impact sensor.
