About B2214

B2214 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 B2214 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 B2214 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 B2214 fault code indicates that the control module responsible for the front passenger window operation has detected a short to battery voltage on the passenger window up switch input. The window switch is monitored by applying a reference voltage to the input and reading the voltage state as the switch is operated, with the up position typically pulling the circuit to ground briefly to command upward window movement. The fault is set when the input continuously reads battery voltage outside of the expected switch operating pattern, indicating the switch signal wire has shorted to a positi...
