You’ll also need to make sure that the new section is properly connected to the rest of the wiring harness and that all of the connections are secure.

Step 4: Test the System

After you’ve repaired the wiring harness, the next step is to test the system to make sure that the B1279 error code has been resolved. You can do this by using a diagnostic tool to read the error codes again and making sure that the B1279 code is no longer present. You should also test the servo motor potentiometer to make sure that it’s functioning properly.

Step 5: Prevent Future Problems

Once you’ve fixed the B1279 error code, it’s important to take steps to prevent future problems from occurring. One of the best ways to do this is to make sure that you’re using high-quality parts when you’re repairing your car. You should also make sure that you’re following the manufacturer’s recommended maintenance schedule and that you’re keeping your car in good condition.

Conclusion

Fixing the B1279 error code can be a bit of a challenge, but with the right tools and know-how, it’s something that you can do yourself. By following the steps outlined in this article, you should be able to diagnose and repair the problem with your car’s servo motor potentiometer foot circuit. Just remember to take your time, be patient, and follow the instructions carefully.
