About B0014

B0014 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 B0014 is stored, the module has detected an electrical-circuit fault in the wiring, connector, or driver associated with the named component.

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 B0014 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

DTC B0014 relates to the right hand front (RHF) seatbelt pretensioner deployment loop, the circuit the Restraints Control Module (RCM) fires to tension the belt at the onset of a crash. The RCM keeps this loop under constant electrical surveillance, comparing its resistance and voltage against stored limits to confirm the pretensioner is connected and serviceable. The code sets when the RCM sees an open, a short to ground or power, or an out of range resistance in the RHF pretensioner circuit that would compromise deployment. With the fault active the RCM disables this pretensioner output, tur...
