I?m in Brasil... shipping cost more than device kkkkk !!!!

I want to repair this one for a spare tool (As I said, I have another that works)

[camil]

Hmm, what about opening both and check for missing components/connections on PCB?

You can try to change only two part - SJA1000T controller and 82C250 CAN driver chip.
If it not helps than the problem is inside main MCU.

Both devices uses MPC2551... they are 100% interchangeable ?

Yes, this is a high-speed CAN transceiver.
