What does it mean when the N3/10 - ME-SFI control module stays on even after the car been off for a while? like it makes a wierd sound like a very fast ticking noise? do i have to replace the module ? is there a faulty wire? and what does the module control?

CCM controls wipers and turn indicators and the courtesy lights I think and probably a whole host of miscellaneous functions. Pre FL it also controls the crash relay which disconnects the battery from the alternator in the event of a crash. No idea why yours ticks. Try searching the forum as there are lots of threads on the CCM.
