Test Q: LFC 49/DTC B2445 - Passenger Crash Sensor Internal Fault
Q1 - Q2:
Normal Operation
The passenger 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 passenger side air bag.
The RCM monitors the two-wire current loop to the passenger side crash sensor for a signal that is out of the expected range. If the RCM detects an out-of-range signal from the passenger side crash sensor, indicating an internal 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
^ damaged wiring on circuit 7-JA4O (YE/VT).
^ damaged wiring on circuit 9-JA4O (BN/WH).
^ damaged passenger side crash sensor.
