Test N: LFC 48/DTC B2444 - Driver Side Crash Sensor Internal Fault

N1 - N2:

Normal Operation
The driver 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 driver side air bag.

The RCM monitors the two-wire current loop to the driver side crash sensor for a signal that is out of the expected range. If the RCM detects an out-of-range signal from the driver side crash sensor, indicating an internal fault, it will store Diagnostic Trouble Code (DTC) B2444 and flash a Lamp Fault Code (LFC) 48 (or a higher priority code if one exists) on the air bag indicator.

Possible Causes
^ damaged wiring on circuit 7-JA39 (YE).
^ damaged wiring on circuit 9-JA39 (BN).
^ damaged driver side crash sensor.
