Harness Connection Method
Recommended harness connection sequence
[1] Start the PC.
[2] While the PC is starting, connect the USB cable to the V.C.I.
[3] After the PC boots to the MUT-III main screen, connect the USB cable to the PC.
Note: Disconnect the USB cable from the V.C.I. after the PC has shut down. However, if the
USB cable is disconnected during use, a warning message indicating device
disconnection such as that shown in Figure 1 appears. Close the message display by
pressing the OK button.
[4] Select the appropriate MUT-III main harness. Connect it to the V.C.I.
[5] Connect the MUT-III main harness to the vehicle diagnosis connector. See Figure 2.
Note: Disconnect the harnesses by performing the above steps in the reverse order.
[6] Turn the V.C.I. power switch ON and verify that the indicator lamp located in the upper right area
of the LCD screen is green.
[7] From the MUT-III system menu, turn the vehicle ignition switch ON and begin the diagnostic
process.
Note: When the version of V.C.I. and the firmware version of V.C.I., which are, mismatch, the
V.C.I. version upgrade process begins. This upgrade typically only occurs once per
MUT-III system upgrade. Normal V.C.I. upgrades take about 1 minute. If a version
upgrade error occurs, restart the V.C.I. by turning V.C.I. power OFF then, while pressing
the Esc button, turn the V.C.I. power switch ON and begin the diagnostic process again.
