About B0000

B0000 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 B0000 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 B0000 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

B0000 is set by the ABS control module when it fails to receive valid serial wheel speed data once the vehicle is travelling above 40 km/h. The ABS system relies on continuous wheel speed data from each corner to monitor individual wheel rotation, detect imminent lock up, and modulate brake pressure during an ABS event. At higher speeds the sensor signal frequency climbs and the module becomes more sensitive to brief dropouts or intermittent loss of the data stream, which is why this fault often sets only during road test conditions and may clear at idle. When the code is active the ABS warnin...
