M.U.T.-II/III DRIVE RECORDER FUNCTION

M1549027300024

1. The SWS monitor cartridge memory can store the

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.

2. If data obtained by the M.U.T.-II/III drive recorder

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
Manual.
NOTE: For the details about the M.U.T.-III drive
recorder function, refer to M.U.T.-III User’s Man-
