DIAGNOSIS FUNCTION


HOW TO READ DIAGNOSIS CODE


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

HOW TO ERASE DIAGNOSIS CODE


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

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.
