Service and Repair of Electronically Controlled Systems in Cars and Trucks

Electronically Controlled Systems

Cars and trucks today are highly complex systems of equipment and electronically controlled systems. The advances in all the various components are things that would be viewed as almost magical just a few years ago. Electronics in particular have advanced what your vehicle can do and many of the things that used to be done mechanically are now controlled by electronics.

The Microchip Has Taken Over Electronically Controlled Systems

You may not realize it, but your vehicle depends on electronically controlled systems that can be as small as half the size of a spark plug. Microchips direct the power of your vehicle to where it is needed so that the vehicle can operate properly. It isn’t just one microchip, either. There can be as many as 30 microprocessor based devices that operate the car once your key is turned in the ignition. In fact, the more luxurious the car, the more of these electronically controlled systems can be found. Some luxury models have as many as 100 electronically controlled systems. They have all taken the place of older mechanical parts that people are so familiar with. Some of the most basic elements of a vehicle that were once mechanically controlled, are now under the direction of electronically controlled systems. These include brakes, cruise control, and even the ability to lock and unlock the doors of your vehicle.

What Are The Typically Included Electronically Controlled Systems in Cars and Trucks?

Even in the most basic models, today’s vehicles include a number of electronically controlled systems which have taken the place of previous mechanical components. For example, mechanical connections which used to operate vehicles have now been replaced with the electronic throttle control. Superior traction and cruise controls are a standard feature of most automobiles and emission systems have been improved through the use of electronic control units. As a result, vehicles are often brought in for repairs not necessarily to have a mechanical part repaired but to have an electronic control unit reprogrammed.
