Hi folks,

I just used JScan to change the tire size on my 2017 Trailhawk from 265/60/18 to 265/65/18. After going through the whole process my Park Assist wouldn't turn on and I got a "ParkAssist Unavailable" error in the instrument cluster. After scanning the car for errors I get a B222A - Vehicle Line Mismatch specifically under the park assist module.

Any thought on how I might fix this? I didn't do anything to the park assist module when I went through the process - just changing tire size...

Thanks

Unfortunately not - I don't know of any fix at this point :(.

I've asked Jscan developer about this situation and unfortunately, he confirmed that this issue is not possible to solve on WK2 with 6 sensor park assist. The only way is back to native size in computer or disable park assist.
