How to Diagnose and Solve B1956 Seat Front Up/Down Potentiometer Feedback Circuit Short To Battery Issues

Introduction

If you’re experiencing issues with your car’s seat adjustment, specifically the front up/down function, and you’ve received a B1956 error code, then you may have a problem with the seat front up/down potentiometer feedback circuit short to battery. This can be a frustrating issue to deal with, but with the right tools and knowledge, you can diagnose and solve the problem yourself.

Step 1: Check the Wiring

The first step in diagnosing the issue is to check the wiring. Start by inspecting the wiring harness for any visible damage or wear. Look for any frayed wires, loose connections, or signs of corrosion. If you notice any issues, repair or replace the damaged wiring.

Step 2: Check the Potentiometer

Next, check the potentiometer. This is the component that measures the position of the seat and sends feedback to the control module. Use a multimeter to test the resistance of the potentiometer. The resistance should increase or decrease smoothly as you move the seat up and down. If the resistance is erratic or doesn’t change, then the potentiometer may be faulty and needs to be replaced.

Step 3: Check the Control Module

If the wiring and potentiometer are both in good condition, then the issue may be with the control module. Use a scan tool to check for any error codes related to the seat adjustment system. If you receive a B1956 error code, then the control module may be faulty and needs 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 and use the correct tools for the job. After replacing the component, clear any error codes using a scan tool.

Step 5: Test the Seat Adjustment System

After replacing the faulty component and clearing any error codes, test the seat adjustment system to ensure it’s working properly. Move the seat up and down and check for any issues. If everything is working correctly, then the problem has been solved.

Conclusion

Dealing with a B1956 error code can be frustrating, but with the right tools and knowledge, you can diagnose and solve the issue yourself. By following these steps, you can identify the faulty component and replace it, ensuring your car’s seat adjustment system is working properly.
