About B2314

B2314 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 B2314 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 B2314 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 Passenger Door Module or Body Control Module monitors the horizontal position feedback potentiometer inside the passenger side power mirror to track the mirror's left to right position for the memory mirror function. DTC B2314 is set when the module detects that the horizontal feedback potentiometer signal is being pulled high to battery voltage instead of varying within its normal range as the mirror moves. This typically indicates a wiring harness short between the signal wire and a 12V supply, or an internal failure in the mirror potentiometer pulling the signal high. When this code is ...
