About B0061

B0061 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 B0061 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 B0061 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 B0061 sets when the Airbag Control Module (ACM) detects a fault in the Left Hand (LH) roof rail airbag deployment loop, the firing circuit for the curtain airbag that runs along the roof rail. The ACM monitors this loop by measuring its resistance and stores the code for an open circuit, a short to ground, a short to voltage, or a resistance that falls outside the calibrated window. The roof rail curtain airbag is a pyrotechnic device that deploys downward to shield the heads of the occupants in a side impact or rollover, so the ACM must confirm the firing loop is healthy at all times.
