About B0054

B0054 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 B0054 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 B0054 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

This code is set by the Supplemental Restraint System (SRS) control module when a malfunction is detected in the signal circuit of the right, passenger side, front impact sensor. The SRS control module continuously monitors the communication and integrity of this sensor circuit so that valid crash data is always available. The fault is triggered if the signal is missing, out of range, or the circuit is open or shorted, checked at key on and during continuous self diagnostics. When this code is set the airbag warning lamp illuminates and the module may be unable to use right side impact data, w...
