The diagnosis address code for the electronic information systems
control unit 1, J794 is the same on all MIB versions. It is:
"5F – Electronic Information Systems"
Ring break diagnostics
The procedure for ring break diagnosis is the same as with the
previous MOST bus system. However, with the MIB, the testing
program for ring break diagnosis has to be invoked on the vehicle
diagnostic tester using the address code 5F.
With the Modular Infotainment System the electronic information
systems control unit 1 J794 is also the diagnostics manager for
ring break diagnosis.
Although the ring break diagnosis sequence has remained the
same, a different tool has to be used for an optical fault on the
MOST150 – the optical substitute control unit VAS 6778. This is
because of the different transmitter and receiver units.
