IPC ACCESS DENIED

[Jose Velderrain]

Good afternoon,

I have been trying to upgrade my cluster for my 2019 F250 xl with a 2" factory cluster to an 8" digital one but, when trying to do reprogramming, because upgrade one is not match to my truck, and also comes with less mileage than the truck has, any single adjustment call for access denied.

writing data to ECU
writing block 1 failed
access denied
service procedure has been interrupted

first thing that I tried was to load as built file from ford, but got that error code,
then the saved file from old ipc, same error
then just a single adjustment and same error
Already tried uninstalling and reinstalling the app

what am I doing wrong?

thanks for the help in advance

using forscan v2.3.67
OBDLINK EX FW 5.10.3

never mind, I just erased the previous profile of my truck in forscan, and tried again and it worked

Hi there, glad you found the answer. Yes the profile was the issue. Any time you makes changes then reconnect to car don't load the profile as the car has changed.
