Code B2322 indicates the body control module (BCM) has detected a short to battery voltage in the driver-side mirror horizontal position feedback potentiometer circuit. This sensor provides mirror position data for memory recall and auto-fold features. The fault prevents accurate mirror position tracking.
The feedback potentiometer inside the mirror assembly develops an internal short to power, sending battery voltage back to the BCM on the signal wire.
The signal wire between the mirror potentiometer and BCM has rubbed through to a constant-power circuit, often in the door jamb boot or mirror base.
Moisture intrusion at the mirror connector or door harness connector creates a conductive path between the signal pin and a power pin.
A fault in the mirror motor assembly's internal wiring or circuit board feeds battery voltage into the potentiometer signal circuit.
The BCM's internal pull-up/down resistor or input protection circuitry for the mirror position sensor is damaged, though this is uncommon.
No. The code will return as soon as the BCM detects the short to battery voltage on the potentiometer signal circuit again. The underlying wiring or sensor fault must be repaired.
No. The BCM is rarely the cause. The vast majority of B2322 codes are caused by the mirror position sensor itself, a wiring short in the door jamb, or connector corrosion. BCM replacement should only be considered after all wiring and sensor tests pass.
Yes, the vehicle is drivable. The fault only affects driver mirror memory/auto features; manual mirror adjustment typically remains functional. However, the mirror may not return to the memorized position after another driver uses the vehicle.
Often yes, because the horizontal feedback potentiometer is integrated into the mirror motor/glass assembly and is not serviceable separately. However, verify the short is not in the door harness or connector before replacing the mirror.
