Test L: LFC 48/DTC B2444 - Driver Seat Side Impact Sensor Internal Fault
L1:
L2:
Normal Operation
The driver seat side impact sensor monitors the severity of a impact event. If the impact event is severe enough, the sensor will signal the Restraints Control Module (RCM) to deploy the driver seat side air bag.
The RCM monitors the two-wire current loop to the driver seat side impact sensor for a signal that is out of the expected range. If the RCM detects an out-of-range signal from the driver seat side impact 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 seat side impact sensor internal fault can be caused by:
^ damaged driver seat side impact sensor.
