How to Diagnose and Solve B1632 Mirror Driver Left Circuit Open Issues

Introduction

If you’re experiencing issues with your car’s mirror driver left circuit, you may have encountered the B1632 error code. This can be a frustrating problem to deal with, but with the right knowledge and tools, you can diagnose and solve the issue on your own. In this article, we’ll provide step-by-step instructions and useful tips to help you fix the B1632 error code and get your car’s mirror driver left circuit working properly again.

What is the B1632 Error Code?

The B1632 error code is a diagnostic trouble code (DTC) that indicates a problem with the mirror driver left circuit. This circuit is responsible for controlling the left-side mirror on your car. When the circuit is open, it means that there is a break in the electrical connection between the mirror and the car’s computer system. This can cause the mirror to malfunction or stop working altogether.

Diagnosing the B1632 Error Code

To diagnose the B1632 error code, you’ll need a few tools, including a digital multimeter and a wiring diagram for your car’s mirror driver left circuit. Here are the steps to follow:

Step 1: Check the Fuse

The first thing to check when you encounter the B1632 error code is the fuse for the mirror driver left circuit. Use your car’s manual to locate the fuse box and find the fuse for the mirror driver left circuit. Use a multimeter to test the fuse for continuity. If the fuse is blown, replace it with a new one and test the mirror again.

Step 2: Check the Wiring

If the fuse is not the problem, the next step is to check the wiring for the mirror driver left circuit. Use a wiring diagram to locate the wires for the circuit and test them for continuity using a multimeter. If there is a break in the wiring, you’ll need to repair or replace the damaged section.

Step 3: Check the Mirror Switch

If the wiring is not the problem, the next step is to check the mirror switch. Use a multimeter to test the switch for continuity. If the switch is faulty, you’ll need to replace it.

Step 4: Check the Mirror Motor

If the switch is not the problem, the final step is to check the mirror motor. Use a multimeter to test the motor for continuity. If the motor is faulty, you’ll need to replace it.
