System: Body  |  Type: Generic (OBD-II Standard)  |  Make: Ford

About B0001

B0001 is a generic (obd-ii standard) body diagnostic trouble code recorded for Ford vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B0001 is stored, the module has detected an open (broken or disconnected) electrical path in the monitored circuit.

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 B0001 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 Restraints Control Module (RCM) continuously monitors the resistance of every airbag squib (inflator) circuit using very small test currents to confirm each firing loop is intact and within the expected range. Code B0001:13 sets when the RCM detects abnormally high resistance, or no continuity at all, on the right hand front (RHF) airbag squib circuit. The break can be anywhere along the path between the RCM, the SRS harness, the clockspring (where the affected airbag is the steering wheel mounted airbag), the airbag connector, and the inflator itself. An open squib circuit means the airba...
