Controller Unit function and purpose

The control unit in a motor vehicle is an electronic module which controls various functions and processes of the engine of the vehicle and other technical systems, controls and monitors. Its origins are the digital control units in the electronic engine control, where they replaced what was formerly the purely electromechanical control of the ignition. They were later used for the electronic control of diesel engines. Through the ever increasing performance of electronic systems and the progress of computer technology control units were developed for an increasing number of technical systems, their functions also became more complex at the same time. Meanwhile, some recent car models have more than seventy control units for controlling various systems such as ESP or ABS special control units.While they are in operation, you will receive the necessary data for the control of various sensors. Instrument clusters are ECUs with speedometer, tachometer and other displays are visible to the driver. Well-known producers include Bosch, Valeo, VEMO, Magneti Marelli and Herth + Buss.

Programming and control unit tuning

Modern control units are often full of small computers with one or more processors, and operate according to the input-processing-output principle (EVA). According to the functions and requirements of a control unit can be programmed using special software.The engine management can moreover be carried out with chip tuning performance-related factors such as ignition or injection quantity selectively optimized around increasing engine performance without consuming more fuel.

Possible defects and repairing the control unit

In addition to malfunctions or the failure of electronic components, moisture can also be the cause of a defective control unit. The reasons for defects are often versatile, according to the specific functions of a control unit. This ranges from the illumination of indicator lights to interference to running the engine or even a total failure of technical systems. For further diagnosis, a control unit can be read out by a computer and special software and hardware.Under certain circumstances, a repair of the defective control unit is possible; otherwise, it must be replaced.
