Where did you get the asbuilt? Did it come with the APIM?

Also, your truck is a Lariat, does it have automatic AC or manual? You have the Sony system, any heated or cooled seats?

it came with the APIM. that was a screen shot while i was connected. i do have auto AC with heated and cooled seats

OK, based on a 2017 Lariat with the like options and what you described, this should be really close.

So, what you’ll do is to open FORScan to the APIM asbuilt page in you pic. At the bottom there is a button called “Load ALL”. Select that and select the attached file. Say OK.
FORScan should indicate it loaded the data. Then select “Write ALL”
The unit will reboot and come back up. See how it runs…

ill give it a shot right now. thanks for the help

Did you try the update to 20282 first? Or in this case downgrade…then see if the zoom works. If it does, then upgrade back to 23188.
