Introduction

If you’re experiencing issues with your car’s mirror driver vertical switch circuit, specifically a B1736 error code, you’re not alone. This issue can be frustrating and confusing, but with the right knowledge and tools, you can diagnose and solve the problem yourself. In this article, we’ll provide step-by-step instructions and useful tips to help you fix the issue and get your car back on the road.

What is the B1736 Error Code?

The B1736 error code indicates a short to ground in the mirror driver vertical switch circuit. This circuit is responsible for controlling the vertical movement of your car’s mirrors. When there is a short to ground, the circuit is disrupted, and the mirrors may not move properly or at all.

Diagnosing the Issue

To diagnose the B1736 error code, you’ll need a few tools, including a multimeter and a wiring diagram for your car’s mirror circuit. Here are the steps to follow:

Step 1: Check the Fuse

The first thing to check is the fuse for the mirror circuit. Use your car’s manual to locate the fuse box and find the fuse for the mirror circuit. Use a multimeter to test the fuse for continuity. If the fuse is blown, replace it and test the mirror circuit again.

Step 2: Check the Wiring

If the fuse is not the issue, the next step is to check the wiring for the mirror circuit. Use a wiring diagram to locate the mirror driver vertical switch circuit and check for any breaks or damage in the wiring. Use a multimeter to test for continuity in the circuit. If there is a break or damage in the wiring, repair or replace the affected wires.

Step 3: Check the Switch

If the wiring is not the issue, the next step is to check the mirror driver vertical switch. Use a multimeter to test the switch for continuity. If the switch is faulty, replace it with a new one.

Solving the Issue

Once you’ve diagnosed the B1736 error code and identified the issue, it’s time to solve the problem. Here are the steps to follow:

Step 1: Repair or Replace the Affected Component

If the issue is with the fuse, wiring, or switch, repair or replace the affected component. Use the steps outlined in the diagnosis section to identify and fix the issue.

Step 2: Test the Mirror Circuit

After repairing or replacing the affected component, test the mirror circuit to ensure it’s working properly. Use a multimeter to test for continuity in the circuit and check that the mirrors move properly.

Step 3: Clear the Error Code

Once you’ve confirmed that the mirror circuit is working properly, clear the B1736 error code. Use an OBD-II scanner to clear the code and ensure that it doesn’t reappear.

Conclusion

Dealing with a B1736 error code can be frustrating, but with the right knowledge and tools, you can diagnose and solve the issue yourself. By following the steps outlined in this article, you can identify the issue, repair or replace the affected component, and get your car’s mirror circuit working properly again.
