ECU - Electric Control Unit or Engine Conrol Unit?

Administrator posted this 21 May 2019

ECU is an Electric Control Unit, but sometimes the acronym means Engine Control Unit. So the question is, what does ECU really mean and how does it influence on the car output?

Actually, ECU is a general term for any electronic unit which controls different vehicle's “branches”. For example, Airbag Control Unit, Heating, Ventilation and Air Conditioning, etc. One car can include 80 ECUs.

ECM (Engine Control Module).

There are different Engine Controllers produced by BOSH, Delphi, GM, Siemens and other less huge enterprises. They can have differences according to the standards, configuration, and principle of operation.

ECM reads parameters of sensors within the engine bay, interpreting the data and adjusting the engine actuators. With the help of inCarDoc app you can to control its functionality and productivity state.

Electronic control units rarely fail, but this can happen. It is difficult to determine the prerequisites and symptoms of failure, as they may relate to completely different components.

Check Engine Light comes on. This signal is well known by all drivers, and it announces that you have problems with the car performance.

When you check the car (OBD) with app inCarDoc, you see several ECM issues, and you able to throw off them with the same app. But, if the problem is still on demand, unfortunately, the risk of ECM dysfunctionality is higher.

The next step you should follow is to examine ECM for its built quality, overheating and for corrosion and destruction. ONLY PROFESSIONALS can do diagnostic of ECM’s electronics specification and to hold fractography.

InCarDoc enables users worldwide to check ECM in a few seconds with all internal processes, which achieve and deliver good performance and operation of all parts and systems of the car.

Drivers get information about following engine parameters in real time:

  • • Engine speed
  • • Engine load
  • • Coolant temperature
  • • Fueling system condition
  • • Vehicle speed
  • • Air pressure
  • • Ignition advance
  • • Intake air temperature
  • • Mass air flow
  • • Throttle Position
  • • Lambda probe (engine mode correction)
  • • Fuel pressure
  • • And others (depends on the car model
