V.C.I. Functions
<When V.C.I. and PC are connected>
2-2-1. Fault Diagnosis
The system diagnoses faults by receiving instructions from
the PC and communicating with the vehicle-installed ECU.
When the system is connected to the PC, V.C.I. keys are
disabled.
[Start Screen]
*When the USB cable is connected to the system, the
screen illustrated on the left appears.
The screen indicates the flow of signals between the PC (P)
and V.C.I. (V) using "P
2-2-2. Fuel Pressure measurement (Not available in US)
The system analyzes faults by measuring fuel pressure
using the Pressure gauge set (MB991637 or MB991981).
Pressure gauge for LP: MB991655 or MB991979
The V.C.I. reads the fuel pressure, which is converted into
voltage value by the pressure gauge. Then the system
converts it back to pressure value and displays it as text or
graph on PC screen. (refer to 11-3-1.)
<With the V.C.I. only>
2-2-3. Measurement Function - Voltmeter / Ohmmeter
The system reads the voltage/resistance value from the trigger
terminal and displays the value on the V.C.I. LCD screen.
1. Connect the measurement adapter to the V.C.I., connect the
test leads to the adapter.
2. Connect the appropriate main harness to the V.C.I., and then
to the vehicle diagnostic leak connector and turn the V.C.I.
power switch ON.
3. Press button to select Voltmeter or Ohmmeter in the
Main Menu (see the illustration on the left), and press the
(Enter) button to begin measurement.
Note:
• Permits measurement of DC voltage within the range of 0-
±40V.
• Permits measurement of resistance within the range of
0-100KΩ.
• Permits displaying the value as text or graph on PC
screen by connecting the V.C.I. to PC. (refer to 11-3-2.)
