actually easy to detect the function function. crystal check with oscillosop. check RX TX serial data and CAN bus. then the eeprom program .... look for a suitable dump file

Thanks...
like that I have much more to learn about electronics, can you please advise on common problems with the speedometer or how to do a check on the MCU

I told you. try to understand more. (1) 5V power supply. (2) the crystal heartbeat occurs. (3) does the serial data get out to the can bus. this is a requirement of the MCU function. you need thanks and reputation first maybe.
