Hi there.The reason the monitors won't reset is that there is a fault code in the OBD-II computer memory. Once the failure indicated by the fault code is repaired, the code can be erased and the vehicle driven through a couple of OBD-II Drive Cycles so the monitors can reset.

how do i find the fault code? nothing showing.
Customer: replied 1 year ago.
What I mean is, there's no check engine light showing, thus, no fault code.

hello? are you there?
Expert:  Juan Crespo replied 1 year ago.
Yes, I am.The fact that there is no check engine light showing does not automatically mean there is no code. If there was no code, the OBD-II monitors would reset. If you'd like, I could upload the OBD-II regs pertaining to Monitor completion.
Customer: replied 1 year ago.
ok, so how do we access the code?
Expert:  Juan Crespo replied 1 year ago.
The onboard computer has to be scanned with a tool capable of retrieving both current as well as pending codes - I don't know your state's regulations, but places like Advance Auto, O'Reilly's, Aamco and others like them will do this for free.
