Engine control modules are the behind the engine management system without it the system would never function. It controls almost every aspect of the engine starting from the ignition timing, emission controls among others. When it comes to emission control the engine accomplishes that though the onboard diagnostics programming. It will also control the engine cooling fun the fuel pump and the charging systems as well.

Some diagnosis will reveal that you have a bad computer changing the computer is possible but you will need the services of a professional to do it successfully. Doing the replacement is actually done in a series of steps. Replacement of the computer is not a simple affair , it is done in a series of steps. The computer will have to be programmed for that particular vehicle before it can be installed into that vehicle and that goes into the specifics such as the year , the make and the model, the engine and other specifics. A remanufactured module supplier will have the information necessary so consider doing all the consultations that you have to do because this is not procedure that you can afford to get wrong.
The programming involved here is not simple you need the tools and the expert because no amount of DIY expertise can pull off the codes here. Engine control modules for your trucks will need you to do some serious research on them before you can go shopping. There are probably hundreds of shops that are selling ECMs but that is not to mean that they are genuine. Buying an ECM that does not meet the quality standards of your truck will be nothing but wasting your time and money.
Make a point of testing the ECM first, ready your vehicle by ensuring that everything is in good condition. Faulty ECMs can be quite easy to detect actually, if it starts detecting problems that are not there then you can tell that is a faulty.
