TROUBLESHOOTING

HEATER, AIR CONDITIONER AND VENTILATION

When detecting the trouble and storing the diagnosis 
code, the ECU connected to CAN bus line obtains 
the data when the diagnosis code is confirmed, 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.
