How to Diagnose and Solve B2312 Mirror Passenger Horizontal Feedback Potentiometer Circuit Failure Issues

Introduction

As a car owner, you may have experienced issues with your car’s mirrors. One of the most common issues is the B2312 Mirror Passenger Horizontal Feedback Potentiometer Circuit Failure. This issue can be frustrating, especially if you rely on your mirrors to drive safely. In this article, we will discuss how to diagnose and solve this issue.

What is B2312 Mirror Passenger Horizontal Feedback Potentiometer Circuit Failure?

B2312 Mirror Passenger Horizontal Feedback Potentiometer Circuit Failure is a fault code that appears on the diagnostic system of your car. It indicates that there is a problem with the mirror’s horizontal feedback potentiometer circuit. The potentiometer is responsible for sending signals to the mirror control module, which adjusts the mirror’s position. When the circuit fails, the mirror may not move or move erratically.

Diagnosing B2312 Mirror Passenger Horizontal Feedback Potentiometer Circuit Failure

To diagnose this issue, you will need a diagnostic tool that can read fault codes. Connect the tool to your car’s OBD-II port and read the fault codes. If the B2312 code appears, it means that there is a problem with the mirror’s horizontal feedback potentiometer circuit.

Checking the Mirror

The first step in diagnosing this issue is to check the mirror. Remove the mirror from the car and inspect it for any damage or wear. Check the wiring and connectors for any signs of damage or corrosion. If everything looks fine, move on to the next step.

Checking the Potentiometer
