Hi Richard,
Since you get connection with the car and the SW (and can read errors) i assume there is no issue with your cable, this should work…. I had once a defect cable and could not connect at all, i bought a new one with switch and now it works fine ( on the correct switch position of course). With Ista, dont use the service / calibration routine and better access the transfer case board directly, there you can reset the oil to zero and calibrate various things, try the different routines (start with new actuator)…. you may want to check again the connectors on the actuator motor and make sure to use the calibration resistor which was on the car before (dont know if you have more then one)….. This way it worked on my car….. But did not fix my other issues below in the forum, at least my tc shows calibrated
Hope this helps for your issue!

Cheers Ralph
