The engine control unit and its function
The terms DME, ECU, injection control unit and PCM are nothing more than different names for engine control units. In the vehicle itself, the engine management computer controls the engine function and monitoring. In order for it to perform this function, it uses actuators as well as sensors. Actuators include the throttle valve, various valves and the ignition coils. Sensors include the accelerator pedal, fuel pressure sensor, the engine temperature sensor and many others. In newer cars, the ECU also controls battery charging, air conditioning and cruise control, among other things. For more information, see Engine control unit Wikipedia. In the following article we will now come to our engine control unit repair.
Internal structure of the injection control unit
For a professional ECU, engine control unit repair A distinction is made between two groups of control units. One is constructed with a normal epoxy resin circuit board, the other consists of ceramic circuit boards and is called a hybrid control unit. The repair of the conventional ECUs is done in the soldering department. During ECU repair, new semiconductors, capacitors and resistors are installed according to OEM specifications. Unfortunately, it is not possible to replace the components of hybrid ECUs, as they are glued and encapsulated on the ceramic circuit board. The ceramic circuit board is connected to the connector via bondings. If these connections are defective, you need a special machine (ultrasonic bonding) to restore them. We show you how this works in the following video.
Diagnose the control unit beforehand
In order to avoid unnecessary effort during the ECU repair, it should be ensured by appropriate tests and diagnostic queries that the ECU is really defective and not, for example, the supply line, earth connection, plug, fuse or another ECU. Unfortunately, we cannot carry out a complete test of the control unit on the table. Our tests are limited to the assemblies that match the fault. If injector 1 is diagnosed as the fault, then we test the complete electronic control of all injectors. Therefore, a good preliminary work is indispensable for us.
