I'm still new to AlfaOBD and only done a couple config changes so far. Will this Calibration Test produce a pass/fail type report? Thanks.

I'm not sure. i've never had any reason to run the test on my truck.

But if you do it, report back and i'll know going forward.

How do you do the calibration procedure..i have a 2017 and i have very little heat..did heater core flush..changed thermostat and new antifreeze..i can see the acuator motor turning the blend door but it could be broke inside..but id like to yry the calibration 1st

There are youtube videos out there. Watched them, but have not personally done it. You hit some control buttons in a certain sequence.
Also, if you have AlfaOBD, you can re-calibrate and test a bunch of functions using the program with an OBD dongle like the OBDLink MX+.

Press and hold the recirc button for 10 seconds, then release the button and press it again, hold until the light starts flashing. When it stops flashing, it's done.
