How to Reset Your Cars Electrical System

Video Source

Modern cars use computers to properly run, display warnings, and relay other information to you. When you need to reset the system, it’s important to do it properly, or you may get warning lights on when the problem is already fixed. This video will show you how to properly reset your system after an electrical repair.

Use a scan tool and plug it into the datalink connector port to get the codes. With the car on but the engine off, you can erase the DTCs on your car. However, you need an expensive tool to fully reset everything. Instead of paying $5,000, you can use one simple tool.

Remove the battery terminals with a socket wrench. Take the car’s CPU out and unscrew the cover to reveal the electronics inside. Grab a small resistor and connect it to the positive and negative connector terminals. Let it drain for about 10mins.

The resistor connects the positive and negative but prevents any problems associated with draining too fast, blowing out important modules for the computer. Put everything back into place and you’re good to go.
