B2444

Pinpoint Test 30: LFC 48/DTC B2444 - DRIVER-SIDE CRASH SENSOR INTERNAL FAULT

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 a 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
A driver-side crash sensor internal fault condition can be caused by:
- damaged driver-side crash sensor.
