The electronic engine control unit - what is it?

The electronic engine control unit is an 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 this 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.

Who should I contact for help?

What is noteworthy, many auto mechanics when they contact 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 non-professional 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 at the company's maintenance station, of course, it is necessary to change the part to a new one.

Is it worth hurrying to the store for a purchase?

Definitely not worth it. Now let's tell why. The point is that not always the reason for the incorrect operation of the ICE 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. Doing the diagnosis is 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 car 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 about the purchased electronic control unit? 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. And the sellers themselves do not aspire to accept the item bought by them from the motorist, even through the court. So be careful and do not make hasty decisions.
