ENGINE CONTROL MODULES (ECM, PCM AND ECU).

Mainly, there are two major problems with ECU (Electronic Controller Units). The all time present and the Random intermittent failure. The first major problem is solved through a ECM  testing bench machine. The second major problem requires temperature, humidity, mechanical and random troubleshooting procedure tests.

All time present failure can be solved by

       - Reprogramming ECM.

       - Repairing customer ECM, IPC and ACCM modules.

         If the unit is not repairable, the failure can be solved by purchased of

       - Re-manufacture ECM modules.

An intermittent failure requires a long time troubleshooting process when frequency time of failure is less than one time per day. External factors like temperature, humidity and vibration will be part of troubleshooting process on ECM and  most of the time we can fix it. For Electronic Controller modules that can not be fix ,like circuit board is cracked,fire burned,internal flooded and random failure. On these cases we offer to the customer the following services.

Random Intermittent Failure can be solved with

      -Re-manufacture ECM Services.
 

Engine Control Module is an electronic unit that manages fuel delivery through injectors, timing advance, and controls everything to make the engine run. Inside, there is a microprocessor as the main component that controls all units. Its software can be upgraded to improve funcionality,efficiency and calibration of the unit and that is called Flash or Reprograming.

Reprograming  ECM, PCM and ECU will set  new calibration values inside EEprom memory and as a direct result it will fix what is known as OEM  drivebility problems. Technical Service Bulletin shows all details about it and this can be fixed with a reprograming process.

Upgraded ECM calibration with latest version of software will allow us to solve  false diagnoses on the ECM like its mentioned on the TSB's. It will not make the Check Engine Light come back because of set false diagnoses codes and any kind of problem derivated from older software calibration.

Also it will improve gas/miles and fix some intermitent throubles described on Tecnical Service bulletins. Flash ECM is recomended when engine tune-up is performed and first step diagnoses for check engine light.

Important notes: 

        1.-Reprograming ECM does not fix any ECM's hardware problems.

        2.-The new upgrade software can not be returned. Once   the

             process start the old software is erased and a new one is

             installed with no return choice.
