How to Diagnose and Solve B1953 Seat Rear Up/Down Potentiometer Feedback Circuit Short To Ground Issues

Introduction

If you’re experiencing issues with your car’s seat, specifically the rear up/down 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 B1953 Seat Rear Up/Down Potentiometer Feedback Circuit Short To Ground?

B1953 is a diagnostic trouble code (DTC) that indicates a problem with the seat rear up/down potentiometer feedback circuit short to ground. This issue can cause the seat to malfunction, making it difficult to adjust the seat’s position. The potentiometer is a device that measures the position of the seat and sends a signal to the car’s computer. When the circuit is shorted to ground, the computer cannot receive the correct signal, causing the seat to malfunction.

Diagnosing the Issue

To diagnose the issue, you’ll need a few tools, including a multimeter and a wiring diagram for your car’s seat. Here are the steps to follow:

Step 1: Check the Wiring

The first step is to check the wiring for any damage or corrosion. Use the wiring diagram to locate the wires for the seat rear up/down potentiometer feedback circuit. Check each wire for continuity using a multimeter. If any wire is damaged or corroded, replace it.

Step 2: Check the Potentiometer

The next step is to check the potentiometer for any damage or wear. Use the multimeter to measure the resistance of the potentiometer. The resistance should change smoothly as you move the seat up and down. If the resistance is erratic or does not change smoothly, replace the potentiometer.

Step 3: Check the Computer

If the wiring and potentiometer are in good condition, the issue may be with the computer. Use a scan tool to check for any DTCs related to the seat rear up/down potentiometer feedback circuit. If the computer is faulty, replace it.

Solving the Issue

Once you’ve diagnosed the issue, it’s time to solve it. Here are the steps to follow:

Step 1: Replace the Damaged Wiring

If the wiring is damaged or corroded, replace it with new wiring. Make sure to use the correct gauge wire and connectors.

Step 2: Replace the Potentiometer

If the potentiometer is faulty, replace it with a new one. Make sure to use the correct part for your car’s make and model.

Step 3: Replace the Computer

If the computer is faulty, replace it with a new one. Make sure to use the correct part for your car’s make and model.
