To understand more

The 7F-6B-11 SSM_ecuStatus Rx error typically indicates that the software is expecting a specific response from the ECU that the MSD85 protocol selection isn't handling correctly in certain hardware versions. By using the MSD80 protocol, the tool utilizes a broader communication handshake that bypasses this reception hang-up while the MSD85 wiring ensures the correct pins are powered for the TC1796 processor.
