    Throttle body calibration

    I just wanted to verify that I will have to perform a calibration relearn procedure after replacing the throttle body on a 2008 Chevrolet 2500 HD 6.0L. I have a Verus Edge with current 20.2.

    Matt,

    Yes, if the Functional Tests have an option for Idle Relearn available. Some GM's have this option in there, some do not. I can't figure out why certain years will offer, and the next will not.

        Isn't that crazy? I don't understand it either.

          It should be listed under Module Setup in the Functional test menu.

              Thank you everybody. Worked just like you said. Here's the menu flow : FUNCTIONAL TEST-MODULE SET UP-IDLE RELEARN-EXIT (or) RESET. I selected the "RESET" option and vehicle left without any fault codes returning.
