When i turn of my engine, the ABS stays On, i mean i can listen like a electric motor that keeps working after sutting down the engine, so i decided to disconect the plug because i think it can drain my battery, so when i disconect i saw a few oxidation, in the electrical conector pins, so do you think that can cause the problem? Can i use electrical grease inside the plug? if so, wht kind of grase did you recomend?
