About B2313

B2313 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 B2313 is stored, the module has detected an open (broken or disconnected) electrical path 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 B2313 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 B2313 is set when the module detects an open circuit in the horizontal feedback potentiometer signal, indicating loss of the position signal that should be present whenever the mirror is moved. The potentiometer is fed a reference voltage and its wiper returns a varying voltage corresponding to mirror position, allowing the module to store and recall preset positions. When...
