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.

Citroen trivia

  • French president Charles de Gaulle's life was saved by Citroën not once, but twice. In 1961 a Citroën DS managed to stay intact despite there being a bomb made of plastic explosive, dynamite, oil, and nails. It even managed to drive away from the scene. In 1962, de Gaulle was attacked again, this time with machine guns, but the Citroën again managed to get away from the would-be assassins.
  • Unfortunately, the founder of Citroën went bankrupt in 1934, even though the cars they produced were selling well and incredibly popular. The company exists today because tyre company Michelin bought the majority of shares in the company.
  • Buying Maserati was definitely a mistake for Citroën. The SM model didn't sell well, and that led to financial difficulties that meant the car company was eventually acquired by Peugeot.
  • Between 1925 and 1935, the Eiffel Tower was just a big, pointy billboard with the word 'Citroën' in bright lights from top to bottom. This was the first use of lights to advertise on the tower, and Citroën renewed the adverts every year until they were bought out by Michelin.
  • The Citroën 2CV Safari had some crazy extra features. It was a four-wheel-drive vehicle, and Citroën decided that four-wheel drive meant that it would be better to have two engines...one at the front and one at the back. The fuel cap sticks out of the driver's door, and the tank was right under the driver's seat!
