Test Z: LFC 49/DTC B2445 - Passenger Side Sensor Is Faulted

Z1:






Z2:






Normal Operation
The passenger 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 passenger side air bag.

The RCM monitors the two-wire current loop to the passenger side impact sensor for a signal that is out of the expected range. If the RCM detects a signal from the passenger 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 side impact sensor fault can be caused by:
^ damaged passenger side impact sensor.
