HOW TO CONNECT THE M.U.T.-III SE
Required Special Tools:
  • MB992744: Vehicle communication interface-Lite (V.C.I.-Lite)
  • MB992745: V.C.I.-Lite main harness A
  • MB992747: V.C.I.-Lite USB cable short
  • MB992748: V.C.I.-Lite USB cable long
cautionTo prevent damage to M.U.T.-III SE, always turn OFF the power supply mode of the electric motor switch before connecting or disconnecting M.U.T.-III SE.
1. Ensure that the power supply mode of the electric motor switch is OFF.
2. Start up the personal computer.
3. Connect special tool MB992747 or MB992748 to special tool MB992744 and the personal computer.
4. Connect special tool MB992745 to special tool MB992744.
5. Connect special tool MB992745 to the data link connector.
noteWhen the special tool MB992745 is connected to the data link connector, the special tool MB992744 indicator light will be illuminated in a green color.
6. Start the M.U.T.-III SE system on the personal computer.
noteDisconnecting M.U.T.-III SE is the reverse of the connecting sequence, making sure that the power supply mode of the electric motor switch is OFF.

1. Connect M.U.T.-III SE to the data link connector. Refer to "HOW TO CONNECT THE M.U.T.-III SE".
2. Turn the power supply mode of the electric motor switch to ON.
3. Perform the CAN bus diagnostics (Refer to ELECTRICAL & POWER CONTROL – LAN system, CAN Fundamental, Basic Inspection, Diagnosis and Repair Workflow EXPLANATION ABOUT THE SCAN TOOL (M.U.T.-III SE) CAN BUS DIAGNOSTICS).
 
 
FREEZE FRAME DATA CHECK
By using M.U.T.-IIISE, the freeze frame data can be checked.
 
 
When detecting fault and storing the diagnostic trouble code, the ECU connected to CAN bus line obtains the data before the determination of the diagnostic trouble code and the data when the diagnostic trouble code is determined, and then stores the ECU status of that time. By analysing each data using M.U.T.-IIISE, troubleshooting can be carried out efficiently. The displayed items are as the table below.
