The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM or ECM,ECU), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems can and do cause many drive-ability related problem such as rough idle and other symptoms.

SOURCE: hi, my engine light on my ssangyong kyron 2006, comes on and when it does, when i accelarate it goes slower, please help

If the light you are referring to is the check engine light! This generates a code when on, if the light was on then it will hold the code in the memory, if you have had the codes read then they would have been able to access the code.....what is the code? From your description it sounds like your vehicle is going into limp home mode to stop further damage, retrieve the active or saved code and this will tell you where the problem area is!

Hi, you need to get this into the dealer ( only they can reset the ecu on this occasion) - its caused by oil seaping thru the loom into the gearbox 'electronic unit' -It needs to be cleaned of oil, rebooted and adjusted - I had the same problem with my Rodius. Loads of garages can clean it all out - only the dealer can reload the software.
