How to Diagnose and Solve B1965 Seat Horizontal Forward/Rearward Potentiometer Feedback Circuit Short To Ground Issues

Introduction

If you’re experiencing issues with your car’s seat, specifically the horizontal forward/rearward potentiometer feedback circuit short to ground, then you’ve come to the right place. This problem can be frustrating, but with the right knowledge and tools, you can diagnose and solve it on your own. In this article, we’ll provide you with step-by-step instructions and useful tips to help you fix this issue.

What is B1965 Seat Horizontal Forward/Rearward Potentiometer Feedback Circuit Short To Ground?

B1965 is a diagnostic trouble code (DTC) that indicates a problem with the seat’s horizontal forward/rearward potentiometer feedback circuit. This circuit is responsible for sending signals to the car’s computer, which then adjusts the seat’s position accordingly. When this circuit is shorted to ground, it can cause the seat to malfunction, making it difficult or impossible to adjust the seat’s position.

Diagnosing the Issue

The first step in diagnosing this issue is to check the seat’s wiring harness for any signs of damage or wear. Look for any frayed wires, loose connections, or corrosion. If you find any issues, repair or replace the damaged parts.

Next, use a multimeter to test the seat’s potentiometer. Set the multimeter to measure resistance and connect the leads to the potentiometer’s terminals. The resistance should increase or decrease smoothly as you move the seat forward or backward. If the resistance is erratic or doesn’t change, then the potentiometer is faulty and needs to be replaced.

If the wiring harness and potentiometer are both in good condition, then the issue may be with the car’s computer. Use a scan tool to check for any DTCs related to the seat’s position sensor. If you find any codes, then the computer may need to be reprogrammed or replaced.

Solving the Issue

Once you’ve diagnosed the issue, it’s time to solve it. If the wiring harness or potentiometer is faulty, then replace the damaged parts. Make sure to use OEM parts to ensure proper fit and function.

If the issue is with the car’s computer, then you may need to take it to a professional mechanic or dealership to have it reprogrammed or replaced. This can be a more expensive solution, but it’s necessary if the computer is the root cause of the problem.

Useful Tips

– Always use OEM parts when replacing damaged components.
– Use a multimeter to test the seat’s potentiometer before replacing it.
– Check the car’s computer for any DTCs related to the seat’s position sensor.
– If you’re unsure about any step in the process, consult a professional mechanic or dealership.

Conclusion

Dealing with B1965 Seat Horizontal Forward/Rearward Potentiometer Feedback Circuit Short To Ground issues can be frustrating, but with the right knowledge and tools, you can diagnose and solve the problem on your own. Remember to check the wiring harness and potentiometer for any damage, test the potentiometer with a multimeter, and check the car’s computer for any DTCs. If you’re unsure about any step in the process, don’t hesitate to consult a professional mechanic or dealership.
