ECU check results, the service data, the
communication data obtained by the function
diagnosis. This communication data can be
displayed as a chart or graphical form.

function has to be stored for long time, the data
can be transferred to the SWS monitor cartridge.
By doing this, you can disconnect the M.U.T.-II/III
to prevent excessive battery drain.
NOTE: For the details about the M.U.T.-II drive
recorder function, refer to M.U.T.-II Reference
