Code Definition

B0010 (12) — LHF Airbag squib circuit shorted to power

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

About B0010

B0010 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 B0010 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) 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 B0010 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) monitors the voltage on the left hand front (LHF) airbag squib circuit to confirm the firing loop stays isolated from any power source until deployment is commanded. DTC B0010 sub code 12 sets when the RCM detects an unintended supply voltage present on that squib circuit, indicating the drive or return wire has shorted to a power feed. A short to power on the squib loop is a serious fault because the stray voltage can defeat the controlled firing strategy and could contribute to inadvertent deployment. When this fault is stored the RCM disables the LHF airb...
