2021 XC60 won't start after ABS module change.

[Paisano]

Hi. As members previously advised, I got a used (5000 miles) ABS ANTI LOCK BRAKE PUMP MODULE UNIT P32214774 to replace the old Р32214772. Took the car to a local exotic garage and they changed the module. However, the car does not start. I have used orbit to set the settings for pilot assist and choose the brakes alternating with dumping and non dumping brakes. However, the car won't start. In fact, it shows a (P) engaged. The mechanic used his scanner to clear the ABS, the did a physical bleeding of the ABS and the car started however, when he came back from a test drive, the car would not start again. So we put the old abs in again and the car starts. What are we doing wrong? Do we need to crone the old unit on to the new? I can Imagine that the new unit is still holding on to the old VIN?
