How to Diagnose and Solve B1718 Seat Driver Forward Switch Circuit Open Issues

Introduction

If you’re experiencing issues with your car’s seat driver forward switch circuit, you may have encountered the B1718 error code. This can be a frustrating problem to deal with, but with the right knowledge and tools, you can diagnose and solve the issue on your own. In this article, we’ll provide step-by-step instructions and useful tips to help you fix the B1718 error code and get your car’s seat driver forward switch circuit working properly again.

What is the B1718 Error Code?

The B1718 error code is a diagnostic trouble code (DTC) that indicates an issue with the seat driver forward switch circuit. This circuit is responsible for controlling the movement of the driver’s seat forward and backward. When the B1718 error code appears, it means that the circuit is open, which can prevent the seat from moving properly.

Diagnosing the B1718 Error Code

To diagnose the B1718 error code, you’ll need a few tools, including a digital multimeter and a wiring diagram for your car’s seat driver forward switch circuit. Here are the steps to follow:

Step 1: Check the Fuse

The first thing to check when diagnosing the B1718 error code is the fuse for the seat driver forward switch circuit. Use your car’s owner’s manual to locate the fuse box and find the fuse for the seat driver forward switch circuit. Use a digital multimeter to test the fuse for continuity. If the fuse is blown, replace it and test the circuit again.

Step 2: Check the Wiring

If the fuse is not the issue, the next step is to check the wiring for the seat driver forward switch circuit. Use a wiring diagram to locate the wires for the circuit and test them for continuity using a digital multimeter. If any of the wires are broken or damaged, repair or replace them as needed.

Step 3: Check the Switch

If the wiring is not the issue, the next step is to check the seat driver forward switch itself. Use a digital multimeter to test the switch for continuity. If the switch is faulty, replace it with a new one.

Solving the B1718 Error Code

Once you’ve diagnosed the issue with the seat driver forward switch circuit, it’s time to solve the problem. Here are the steps to follow:

Step 1: Replace the Faulty Component

If you’ve identified a faulty component during the diagnostic process, replace it with a new one. This could be a blown fuse, a broken wire, or a faulty switch.

Step 2: Test the Circuit

After replacing the faulty component, test the seat driver forward switch circuit again using a digital multimeter. Make sure that the circuit is functioning properly and that there are no more error codes.

Step 3: Reassemble the Seat

Once you’ve confirmed that the seat driver forward switch circuit is working properly, reassemble the seat and test it again to ensure that it’s functioning as it should.

Conclusion

Dealing with the B1718 error code can be frustrating, but with the right knowledge and tools, you can diagnose and solve the issue on your own. By following the steps outlined in this article, you can get your car’s seat driver forward switch circuit working properly again and enjoy a comfortable ride.
