Despite being a robust version, technicians may encounter specific issues with this hardware: Despite being a robust version, technicians may encounter

For circuit-level repairs, search for Boundary Scan and JTAG testing guides which explain how to test high-density PCBs using standard IEEE protocols.

Often caused by cold solder joints on the RS232 port or the main microcontroller. "Re-flowing" the board with a heat gun can sometimes resolve this.

If the tool can communicate with some modules but not others (e.g., it sees the Engine but not the ABS), one of the physical relays on the PCB might be stuck.
