About B2350

B2350 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 B2350 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 B2350 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 detect driver inputs for turn signals, wipers, washers, headlights, and high beams. DTC B2350 is set when the BCM detects a voltage on one of the steering column switch input circuits that exceeds the expected range, indicating a short to battery voltage. The column switches are typically resistor ladder or ground signaled, so the BCM expects a defined voltage when each switch is operated. When this code is set, the affected function may operate continuously or erratically, false warning indicators may ...
