My guess would be a bad capacitor or a bad solder joint. Electrolytic caps go bad with age and heat and can become intermittant and bad solder joints will expand and contract and cause that failure. Personally,having a great deal of experience fixing electronics,my first step would be to hit the board with a hair drier until it fails,then hit the various parts with a can of cold spray until it works.[email protected] said:Hi,
After 16 years of service and 200K miles my ECM fails when warm -- (Check Trans light comes on).
I have an ebay replacement in the car now but do not know how long it will last.
Can anyone recommend a reputable shop that repairs ECMs?
