It is impossible to know what to repair/replace without understanding the problem and testing/checking the ECM. It can be anything from a bad solder to a burnt out printed circuit board.
Without the echematic of the ECM, you would be guessing what could be wrong.
Thumb of rule for DIY on ECM is to look out for leaking capacitors and cold (cracked) solders. Other than that there is nothing much that you can do for repairs.
