hi my name is Jose i have a Honda civic coupe 2003 before the maintenance required led was off but now that light goes blinking for a while after that it automatically goes off i already went to check it with a obd II scanner and it said that has nothing also they check all the system and they said me that everything was ok, but i don't know why still blinking the maintenance required light some one told me that probably the computer is scaning all the system and thats why it blinks others told me that maybe a trouble with the engine that is not dangerous for the engine i don't know what to belive please help me i will be very thankfully if you can give me an idea what to do
