CAUTION

For vehicles with CAN
communication, use M.U.T.-III
main harness A to send
simulated vehicle speed. If you
connect M.U.T.-III main harness
B instead, the CAN
communication does not
function correctly.

HOW TO READ DIAGNOSIS CODE

Refer to GROUP 00

− Diagnosis function .

HOW TO ERASE DIAGNOSIS CODE

Refer to GROUP 00

− Diagnosis function .

CHECK OF FREEZE FRAME DATA

The freeze frame data can be checked by using the
M.U.T.-III.
When detecting fault and storing the diagnosis code,
the ECU connected to CAN bus line obtains the data
before the determination of the diagnosis code and
the data when the diagnosis code is determined, and
then stores the ECU status of that time. By analysing
each data from M.U.T.-III, the troubleshooting can be
performed more efficiently. The displayed items are
as the table below.
