Code B2320 Description
The B2320 diagnostic trouble code (DTC) indicates a Mirror Driver Horizontal Feedback Potentiometer Circuit Failure. In simpler terms, this means there is an issue with the feedback mechanism that controls the horizontal movement of the driver side mirror. The mirror on the driver's side of the vehicle is typically adjustable both vertically and horizontally, allowing the driver to set the mirror to their desired position for optimal visibility. The feedback potentiometer is a sensor that detects the position of the mirror and sends this information to the vehicle's control module. If this sensor fails or malfunctions, it can cause the mirror to become unresponsive or erratic in its movements, affecting the driver's ability to properly adjust the mirror.
Common Causes of B2320
- Faulty mirror feedback potentiometer
- Wiring issues or loose connections in the mirror control circuit
- Corrosion or damage to the mirror control module
- Water or moisture intrusion affecting the mirror components
- Impact or physical damage to the mirror assembly
Symptoms of B2320
- Inability to adjust the driver side mirror horizontally
- Mirror moves erratically or inconsistently when trying to adjust it
- Mirror gets stuck in one position and does not respond to adjustment commands
- Warning light on the dashboard related to mirror control system
- Possible loss of other mirror control functions
How to Fix B2320
- Diagnose the issue by checking the mirror feedback potentiometer, wiring, and control module for faults
