How to Diagnose and Solve B1951 Seat Rear Up/Down Potentiometer Feedback Circuit Open Issues

Introduction

If you’re experiencing issues with your car’s seat, specifically the rear up/down potentiometer feedback circuit, you may be dealing with the B1951 error code. This can be frustrating, but don’t worry – with a little bit of knowledge and some DIY solutions, you can diagnose and solve this problem on your own. In this article, we’ll provide you with step-by-step instructions and useful tips to help you fix this issue and get your car’s seat back to working properly.

What is the B1951 Error Code?

The B1951 error code is related to the rear up/down potentiometer feedback circuit in your car’s seat. This circuit is responsible for providing feedback to the car’s computer about the position of the seat. When this circuit is open, it means that there is a break in the circuit and the computer is unable to receive feedback from the potentiometer. This can cause the seat to malfunction and not move properly.

Diagnosing the Issue

The first step in diagnosing the B1951 error code is to check the wiring and connections in the rear up/down potentiometer feedback circuit. Start by checking the wiring harness for any signs of damage or wear. If you notice any damage, replace the wiring harness.

Next, check the connections in the circuit. Make sure that all connections are secure and free of corrosion. If you notice any corrosion, clean the connections with a wire brush or sandpaper.

If the wiring and connections are in good condition, the issue may be with the potentiometer itself. To test the potentiometer, use a multimeter to check the resistance across the potentiometer. The resistance should change as the seat moves up and down. If the resistance does not change, the potentiometer may be faulty and will need to be replaced.

Solving the Issue

Once you have diagnosed the issue, it’s time to solve it. If the issue is with the wiring or connections, replace any damaged wiring and clean any corroded connections. If the issue is with the potentiometer, replace it with a new one.

When replacing the potentiometer, make sure to follow the manufacturer’s instructions and use the correct tools. It’s important to disconnect the battery before starting any work on the seat to avoid any electrical shocks.

Useful Tips

– Always disconnect the battery before working on the seat to avoid any electrical shocks.
– Use a multimeter to test the resistance across the potentiometer.
– Follow the manufacturer’s instructions when replacing the potentiometer.
– Check the wiring and connections for any signs of damage or wear.
– Clean any corroded connections with a wire brush or sandpaper.

Conclusion

Dealing with the B1951 error code can be frustrating, but with a little bit of knowledge and some DIY solutions, you can diagnose and solve this problem on your own. By checking the wiring and connections and testing the potentiometer, you can identify the issue and replace any faulty parts. Always remember to follow the manufacturer’s instructions and use the correct tools to avoid any further damage.
