About B2351

B2351 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 B2351 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 B2351 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 Body Control Module (BCM) monitors the steering column multifunction switch circuits to interpret driver inputs for turn signals, wipers, washers, headlights, and high beams. DTC B2351 sets when the BCM detects a general failure on one of the steering column switch input circuits, meaning the input has fallen outside the expected resistance or voltage range for any defined switch position. Unlike a specific short to battery or short to ground code, this code indicates an unrecognised pattern or a fluctuating input that does not match any valid switch position. When this code is set, the af...
