How to Diagnose and Solve B1759 Seat Driver Rear Down Circuit Short To Battery Issues

Introduction

If you’re experiencing issues with your car’s seat, specifically the driver’s seat, and you’ve received a B1759 error code, then you’re in the right place. This error code indicates that there is a short circuit in the driver’s seat rear down circuit, which is causing it to malfunction. In this article, we’ll guide you through the process of diagnosing and solving 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 that connects to the driver’s seat. Look for any signs of damage, such as frayed wires or loose connections. If you find any damage, you’ll need to replace the wiring harness.

Step 2: Check the Fuse

If the wiring harness looks fine, the next step is to check the fuse. Locate the fuse box in your car and find the fuse that corresponds to the driver’s seat. Check if the fuse is blown or damaged. If it is, replace it with a new one.

Step 3: Check the Seat Switch

If the wiring and fuse are both fine, the next step is to check the seat switch. The seat switch is located on the side of the driver’s seat and is responsible for controlling the movement of the seat. Check if the switch is working properly by moving the seat up and down. If the switch is faulty, you’ll need to replace it.

Step 4: Check the Seat Motor

If the seat switch is working fine, the next step is to check the seat motor. The seat motor is responsible for moving the seat up and down. To check if the motor is working properly, disconnect the wiring harness from the motor and use a multimeter to check the resistance. If the resistance is within the manufacturer’s specifications, the motor is working fine. If not, you’ll need to replace the motor.

Step 5: Check the Control Module

If all the above steps have been checked and the issue still persists, the final step is to check the control module. The control module is responsible for controlling the movement of the seat. To check if the control module is working properly, use a diagnostic tool to scan for error codes. If the control module is faulty, you’ll need to replace it.

Conclusion

In conclusion, if you’re experiencing issues with your car’s driver’s seat and have received a B1759 error code, there are several steps you can take to diagnose and solve the issue. Start by checking the wiring, fuse, seat switch, seat motor, and control module. By following these steps, you’ll be able to fix the issue and get your car’s seat working properly again.
