Namely, the starter does not turn. Diagnostics using the Launch, Thinkdiag, Kingbolen, Diagzone, Ediag scanner Kingbolen, Ediag, Diagzone, Launch showed that there is no connection with the engine control unit. We are looking for where the power supply disappeared. The starter is working properly, it turns, everything is fine with the wiring, there are contacts everywhere, there is power everywhere. All fuses are intact, there is voltage on the fuses. The starter relay is working, the main relay is also working. All power comes to the engine control unit. We remove the engine control unit. How to open the engine control unit. Let's say after opening the engine control unit it turned out that during washing water got into the engine control unit, got on the electronic board, on the microcircuit and created oxidation that shorted the legs of the microcircuit. We clean the electronic board, cover it with varnish and re-glue the control unit. After all the procedures and repairs, the car started, communication with the unit was established, there are no errors and everything works fine.
