You have codes stored, is your CEL also on? If so you wont pass anyway. For reading the codes what are you using? If durametric it will give you the DTC also. You can then look in the FSM for how to test that code.

As far as turning on the monitor....you can't. you have to drive until it sets itself to passing. The dealer can't do it either as that would equate to being able to bypass emission testing.
