B0010 (1A) — LHF Airbag squib circuit resistance low

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 signal or supply voltage lower than the expected operating range.

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) continuously measures the resistance of the left hand front (LHF) airbag squib firing loop, which must sit within a narrow window that represents a healthy squib element and clean wiring. DTC B0010 sub code 1A sets when that measured resistance falls below the expected range, which usually points to a partial short between the squib wires, a degraded squib element, or a parallel leakage path reducing total loop resistance. Low loop resistance can upset the current delivered to the initiator and the timing of deployment, so the RCM treats it as a deployment r...
