It wasn’t that long ago that cars were designed with a basic electrical system. Wiring, fuses, and relays helped power basic things light lights, dashboard messages, and the radio. And there are still a lot of older cars on the road that don’t have any more bells and whistles than this.
But the vast majority of cars on the road today have a much more complex electrical system to power things like DVD players, automatic controls for doors and windows, navigation systems, mobile devices, and satellite radio.
And dashboard messaging is no longer limited to letting you know the emergency brake is on or flashing you with the dreaded “Check Engine” light. Now many cars are designed to monitor tire pressure in all four tires, let you know if a door is open, track the temperature inside and out, and much more.
With a greater demand for features powered by electricity in your car, there’s a greater chance for something to go wrong. And it does from time to time. Ever get a dashboard message you don’t recognize, and have to break out the owner’s manual or look it up online? It happens.
Diagnostic Tools Can Help Identify Electrical Problems
Then what? When we service cars with electrical problems, one of the first things we do is connect the car’s computer to our diagnostic tools. In a few minutes, our tools can gather a lot of information about your car and help identify potential problems, both electrical and mechanical.
Sometimes the solution to an electrical problem is pretty straightforward. Replace a fuse or sensor. Change out a relay. Replace wiring damaged by corrosion or worn out over time.
How to Reboot Your Car’s Electrical System
But is it always that way? No. In fact, we sometimes resort to using a technique that’s a lot like hitting Ctrl+alt+delete when your computer starts acting up. Giving your car a reboot can sometimes correct electrical problems. And it’s easy. Disconnect the battery from both terminals, touch them together, wait five minutes, and then reconnect.
In many cases it helps get that electrical problem unstuck, a lot like rebooting your computer or resetting a wireless router to get your Internet signal working again.
