How to Diagnose and Solve B2355 Passenger Mirror Horizontal / Vertical Feedback Potentiometer Circuit Open Issues

Introduction

If you’re experiencing issues with your passenger mirror’s horizontal or vertical feedback potentiometer circuit, you may be dealing with a B2355 error code. This can be frustrating, but don’t worry – with a little bit of know-how, you can diagnose and solve the problem yourself. In this article, we’ll walk you through the steps to identify the issue and provide you with some DIY solutions to fix it.

What is a B2355 Error Code?

A B2355 error code is a diagnostic trouble code (DTC) that indicates an issue with the passenger mirror’s horizontal or vertical feedback potentiometer circuit. This circuit is responsible for providing feedback to the mirror control module, which allows it to adjust the mirror’s position. When this circuit is open, the mirror won’t be able to adjust properly, and you’ll see the B2355 error code.

Diagnosing the Issue

To diagnose the issue, you’ll need a multimeter and a wiring diagram for your vehicle. Here are the steps to follow:

Step 1: Check the Wiring

The first thing to check is the wiring for the potentiometer circuit. Use your wiring diagram to locate the wires for the circuit and check for any breaks or damage. If you find any issues, repair or replace the wiring as needed.

Step 2: Check the Potentiometer

Next, you’ll need to check the potentiometer itself. Use your multimeter to test the resistance of the potentiometer. If the resistance is outside of the manufacturer’s specifications, you’ll need to replace the potentiometer.

Step 3: Check the Mirror Control Module

If the wiring and potentiometer are both in good condition, the issue may be with the mirror control module. Use your multimeter to test the voltage and ground connections to the module. If these are both good, the module may need to be replaced.

Fixing the Issue

Once you’ve identified the issue, you can take steps to fix it. Here are some DIY solutions to try:

Replace the Potentiometer

If the potentiometer is the issue, you can replace it yourself. Simply remove the old potentiometer and install the new one according to the manufacturer’s instructions.

Repair or Replace the Wiring

If the wiring is the issue, you’ll need to repair or replace it. This can be a bit more involved, but with the right tools and some patience, you can do it yourself.

Replace the Mirror Control Module

If the mirror control module is the issue, you’ll need to replace it. This can be a bit more challenging, as you’ll need to remove the door panel to access the module. However, with some basic tools and a little bit of know-how, you can do it yourself.

Conclusion

Dealing with a B2355 error code can be frustrating, but with the right tools and some DIY know-how, you can diagnose and solve the issue yourself. Whether you need to replace a potentiometer, repair some wiring, or replace the mirror control module, you can do it yourself and save some money in the process.

FAQs

1. Can I drive my car with a B2355 error code?

Yes, you can still drive your car with a B2355 error code. However, your passenger mirror won’t be able to adjust properly, so you’ll need to be extra careful when changing lanes or backing up.

2. How much does it cost to fix a B2355 error code?

The cost to fix a B2355 error code will depend on the specific issue and the make and model of your vehicle. If you’re handy with DIY repairs, you can save some money by fixing the issue yourself.

3. Can I prevent a B2355 error code from happening?

There’s no surefire way to prevent a B2355 error code from happening, but you can reduce the risk by keeping your mirrors clean and avoiding any impacts or damage to the mirror housing. Regular maintenance and inspections can also help catch any issues before they become bigger problems.
