Does anyone have any information on retrieving trouble codes for a 2004 MSX 140? The "Check engine" message is coming on, on a friends MSX 140. Does it require a special scan tool or can it be accessed by a flash code? Is there a diagnosis connector that can be jumped for trouble codes? The engine runs fine with no loss of power or performance. I am a Honda auto tech. and am trying to help him find out if it needs to go to a dealer for service, or if we can find out what is going on to diagnose it ourselves.
