    start with whether someone has dropped some GPS locator using CAN from the socket. if CAN was dead, the car would be dead for sure.

    Maybe you have a released CAN somewhere in the bundle, recently I fought the Ford E150 Raptor from 2013 and the same symptom - no connection to anything, one frayed CAN wire.

    you need to turn off all ECUs on Can and measure R = 120 (60) Ohm + beam
    check + 12v and ground on OBD

    I am sorry that it is so late, but I just sat on the net, the power supply is on the OBD. Exactly it connected to the radio and the display will fight the installation tomorrow.

    I bought the controller online as a used one, I soldered it from the previous eeprom, the communication was recovered, it showed errors, the car started and
    Everything's fine

    But did you buy an engine controller or USM? Thank you in advance for your help.

    In my case, it is master 2.5 Bosch 0 281 013 363 engine controller.
