unable to calibrate touchscreen

[PV-EV]

Our VDS (touchscreen) has gone wonky. Icons on the bottom right side of the screen are no longer accessible. When you press the screen a spot below and to the left of where you press is activated. So when on a drive screen I press the right arrow the home link is activated. I tried the touchscreen calibration but it fails and says service required. It is also a little tricky to get out of the endless loop that puts you in (hold your finger on the screen until in blanks and count to 30 before releasing). I pulled the connector on the VDS but that didn't work. I also pulled the connectors on the VMS but that failed to fix anything either. The Seatle service center has never heard of this problem before. Anyone have any suggestions before I order a new VDS?

Searched around and found this that might help you:

Maybe it will help to do a hard reset? Take out the battery fuse in the front, and main fuse in the back and wait 3 minutes before you put them back in.

Its worth a try for sure... Thanks for finding that.

Diagnostics menu - VDS - MfgTest - Touch Cal

Performing the hard reset did not solve this problem

Did you ever get it working?

Nope. And the diagnostic screen menu is the same calibration program as the regular one.

Sorry to hear that. Perhaps a salvage unit swap?, though it may be coded to the VIN and/or other control units and not work properly.

Last I checked new ones were available from Tesla. But at 650 I decided I could live without it. I’m thinking it might just be some passive components on the board but I haven’t pulled it out to look since I first had the problem.
