DIAGNOSTIC FUNCTION

HOW TO READ DIAGNOSIS CODE

Connect the M.U.T.-III to the 16-pin diagnosis connector, and read a diagnosis code (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - Diagnosis Function

HOW TO ERASE DIAGNOSIS CODE

Connect the M.U.T.-III to the 16-pin diagnosis connector, and erase a diagnosis code (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - Diagnosis Function

CHECK OF FREEZE FRAME DATA

The freeze frame data can be checked by using M.U.T.-III (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - Diagnosis Function

).
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.
