How to Diagnose and Solve B1963 Seat Horizontal Forward/Rearward Potentiometer Feedback Circuit Open Issues

Introduction

If you’re experiencing issues with your car’s seat not moving forward or backward, it could be due to a B1963 error code. This code indicates a problem with the seat horizontal forward/rearward potentiometer feedback circuit being open. In this article, we’ll go over how to diagnose and solve this issue.

Step 1: Check the Wiring

The first step in diagnosing this issue is to check the wiring. Start by inspecting the wiring harness for any visible damage or loose connections. If you notice any issues, repair or replace the wiring as necessary.

Step 2: Check the Potentiometer

If the wiring looks good, the next step is to check the potentiometer. This component is responsible for measuring the position of the seat and sending that information to the control module. To check the potentiometer, use a multimeter to measure the resistance across the potentiometer terminals. The resistance should change smoothly as you move the seat forward and backward. If the resistance is erratic or doesn’t change, the potentiometer may be faulty and will need to be replaced.

Step 3: Check the Control Module

If the wiring and potentiometer are both in good condition, the issue may be with the control module. Use a scan tool to check for any error codes related to the seat control module. If you find any codes, clear them and see if they return. If the codes persist, the control module may be faulty and will need to be replaced.

Step 4: Replace the Faulty Component

Once you’ve identified the faulty component, replace it with a new one. Make sure to follow the manufacturer’s instructions for installation and calibration.

Useful Tips

– Always disconnect the battery before working on any electrical components in your car.
– Use a wiring diagram to help you identify the correct wires and components.
– If you’re not comfortable working on electrical components, it’s best to take your car to a professional mechanic.

Conclusion

If you’re experiencing issues with your car’s seat not moving forward or backward, it could be due to a B1963 error code. By following the steps outlined in this article, you can diagnose and solve this issue and get your seat moving again.
