About B2441

B2441 is a generic (obd-ii standard) body diagnostic trouble code. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B2441 is stored, the module has detected a sensor-related fault — the reported value from the named sensor is out of spec.

Scanning & clearing: Body (B) codes are often stored in the body control module, airbag module, or climate module. A basic OBD-II tool usually will not read body codes — an enhanced or OEM-level scan tool is typically required.

Because B2441 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The B2441 code indicates a fault detected with the driver side crash sensor mounting. The Restraint Control Module (RCM) monitors the side impact sensor located in the driver B pillar or lower door area for both electrical integrity and correct mounting orientation. This code sets when the module determines the sensor is not properly mounted, has lost mechanical integrity with its mounting surface, or has detected an orientation outside expected parameters. When this fault is set, the SRS warning light illuminates and the side airbag and curtain airbag deployment capability may be disabled, le...
