Or you can just unplug the negative and create a load on the ECM, that'll clear it out, but yeah, to be sure, 30 mins at the most will do it.

True, The FSM is going to say thirty seconds, But that'* on a perfect system with minimal resistance. Thirty minutes is foolproof as our cars age.

Please ask related questions in your other topic rather than posting multiple topics about the same issue.
