The electronic engine control unit - what is it?

The electronic engine control unit isan integral part of every modern car. This element is a kind of system that is responsible for the operation of the engine, transmission and other machine assemblies, including electronic ones. In simple words, the control unit is the brain of the car, from the well-coordinated work of which depends the serviceability of all the constituent elements.

Among motorists there is an opinion that thisthe part is not subject to any repair and restoration, even in the service center. But it is still possible to repair the automatic transmission control unit, but only if the scale of the disaster is not critical. Of course, for the repair of this part you will have to pay a lot of money, but this is much less than the cost of the new unit.

To whom to apply for help?

What is noteworthy, many auto mechanics atreferring to them at the SRT for such repairs simply refuse to perform this work: they say, only the replacement of a part for a new one will save the situation. But here it is necessary to take into account one moment that only nonprofessional workers say so. In the corporate technical center, where many car owners are afraid to call in search of more economical options, such a service exists. However, if the severity of the failure does not allow the repair of the unit even on a proprietary maintenance station, of course, it is necessary to change the part to a new one.

Should I rush into the store to buy?

Definitely not worth it. Now let's tell why. The fact is that not always the reason for the incorrect operation of the engine and all electronic mechanisms is the control unit. Therefore, before you purchase a new part, be sure to diagnose the car. So you can find out what is really the source of breakdowns. Do the diagnosis best on the same, branded STO. Please note that professional technicians after completing this work can not only make a list with a list of faulty employees, but also explain to you what and where it came from.

I did not send the machine for diagnostics in time, bought a new unit and only after installation realized that the reason was not in it. What to do?

Yes, the situation is quite problematic. The search and purchase of the unit took a lot of time and money, but after its replacement, the engine and gearbox still work intermittently. In this case, the first step is to turn to the diagnosis. Yes, yes, to the one that was ignored when buying a new unit. There your machine will be examined, will make a list of necessary parts to replace and will reveal the true source of breakdowns (but certainly not the pump control unit).

But what to do with the purchased electronic unitmanagement? As if this did not seem insulting, but it can be left only as a souvenir (or until the moment when the old one breaks down). The fact is that even under the law it is impossible to return this item back to the store. Yes, and the sellers themselves are not eager to take the part purchased from them by the motorist, even through the court. So be careful and do not make hasty decisions.
