B2445

Pinpoint Test 31: LFC 49/DTC B2445 - PASSENGER-SIDE CRASH SENSOR INTERNAL FAULT

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