About ECU

What is the ECU/what does it do?

The term ECU (Electronic Control Unit) is a universal name given to a variety of electronic control systems found in a car. Collectively they make up the car's computer or brain which controls and regulates key components of the vehicle.

Getting into the details of the ECU

ECU’s are located within the dashboard or engine bay. It is often possible to ‘read’ or interrogate your car's various ECU’s using a laptop computer with relevant software and cable or a dedicated reader via a connection port which is usually located in the dashboard. This method is used by mechanics for diagnosis of certain vehicle faults.

An ECU controls or governs aspects of a car's systems including, but not limited to, the engine, ABS, suspension, automatic gearbox and power steering.

What if something goes wrong with the ECU?

Like any electronic component an ECU can fail for a number of reasons including short circuits, dry solder joints, water damage or age. Diagnosis is generally much easier with the correct reader which can be used to obtain error codes from ECU.

Volvo trivia

  • There are more than 2000 Volvo dealerships around the world, with the highest number in the US and the UK.
  • Volvo is one of the oldest companies in the world to be trading on the Stock Exchange. They have been trading consistently since 1935. The majority of car manufacturers didn't even exist when the Stock Exchange opened.
  • The Volvo 240 is considered the benchmark by which all car safety standards are set. The 240 is so well identified with driver, passenger, and pedestrian safety that the US government even purchased 24 of them just to test for themselves how safe they were.
  • To test the strength of their vehicles, Volvo puts them through rigorous tests, including using a machine in their Gothenburg lab that was designed to test how buildings cope in earthquakes.
  • Volvo was the first manufacturer to install fog lights on the front and rear of their cars.
