i know ihave lifted it but same thing

if you say that all connections are good, then I disconnected everything that happens, I try to run the dash and start again with the connections ...
remember to lift pin 38 of the MCU and connect cable 12 UPA. UPA cable 11, the pin 18 of the MCU, etc, etc...
if it fails then try lifting pin 13 of the MCU and connect it to cable 10 UPA...

good luck
