To turn on the VCI module, first connect the main DLC cable from the VCI module to the vehicle DLC
connector and press the main power switch.
If the vehicle DLC is not configured to provide power to the VCI, the cigar power cable must be used.
If needed, the cigar power cable can be connected directly to the vehicle battery by using the battery
extension cable.

WARNING
z Do not use the Power switch of the VCI Module in Flight Record mode.
z In Flight Record mode, VCI module and Trigger module automatically turn On/Off
depending on IG Key status.
The VCI equipment has an LED display for indicating VCI operating conditions.
Figure 2. LED status on VCI module

Color of LED reflects the active function. Sub LED’s show which function is currently operating on the
VCI module: Normal (diagnosis) or flight record mode.
z Green: Normal (diagnosis) mode
z Red: for Flight Record mode.
VEH. COMM
The current condition of Vehicle communication to the VCI module can be monitored using this LED.
z This LED is Green. Note that this LED may flicker during operation.
PC COMM
Communication between PC and VCI is confirmed based on LED color:
z Red color indicates wireless LAN connection and Green indicate s USB cable connection.

To turn off the VCI module, press the power switch for 2~3 seconds or disconnect the DLC or cigar
power cable.
Trigger module switch operation (Enter / Cancel)
“ENTER” and “CANCEL” Buttons are on the trigger module. In Flight Record mode The VCI module
automatically starts recording data whenever it is switched on and each time the “ENTER” button is
pressed.
z Recorded communication data is stored in the VCI module memory by pressing “ENTER”
function during the Flight Record mode.
z Pressing the “CANCEL” button restarts the data recording process.
Trigger module LED (Power / Ready)
Trigger module has two dif f erent LED indicators.
z Power LED: Red Indicates DC power is available for VCI module.
z Ready LED: Green light displays two different ways. The flickering green light means the
recorded communication data is being stored after pressing the “ENTER” button and the
other normal green light means it is now collecting the data from the ECU.

Installation of VCI Module
and DLC Main Cable
Hardware
Module: A–01-004 (p.01)
First, confirm the position of the Data link Connector (DLC).
The location of the Data Link Connector (DLC) may vary depending on the type of vehicle.
z It is usually installed in the lower instrument panel, on the driver’s side.
z The DLC may be installed in the engine room. Check for the pro per location on each vehicle.

The VCI should be secured in a safe location when operating the vehicle to avoid interference with
other vehicle equipment.
Be sure that the DLC main cable is connected securely.

Figure 3. Example Installation of VCI module
Some GDS features require using the USB cable instead of wireless LAN while communicating
between the Information Terminal and the VCI module.
While installing the USB cable to the VCI module, the USB cable must be tightly connected in order to
avoid communication loss.
When removing the USB cable, press the connector lock tab first, and then disconnect the cable.

Installation of Trigger Module
and Cigar Power Cable
Hardware
Module: A–01-005 (p.01)
The Trigger module has two purposes.
When the ignition key is turned to the IG ON position, the trigger module commands the VCI to turn
ON. At that time, the VCI (if configured for flight recording) is ready to store ECU data.
When the ENTER button on the trigger module is pressed, the VCI will start recording vehicle ECU
data.
Cigar jack from the trigger module cable and round connector with 6pins are connected to the vehicle
and the VCI module respectively .
Figure 1. Installation of trigger module and VCI
Connect the trigger module to the cigar lighter or vehicle 12V power point. The trigger module should
be secured in a safe location when operating the vehicle to avoid interference with other vehicle
equipment

Self Test Adapter
Hardware
Module: A–01-006 (p.01)
The self-test functions are used to check the DLC Main Cable and specific related circuits. Not all VCI
circuits are checked with the self-test functions.
Basic operation of the self-test function is the loop-back theory.
Loop-back theory is verification between sent data from the VCI module and returned data, which
passed through the pins of all the outside connectors during the self-test.
Some communication circuits such as high speed CAN, low speed CAN and SAE-J1708, cannot be
checked with loop-back tests.
There are 2 self-test steps included in the Self Test function on the Configuration menu.
z Step A: Performs test functions by automatically changing circuit configurations at the inner end
of DLC connector of the VCI module.
z Step B: Performs test functions on the DLC main cable using the self-test adapter which will short
all the terminals (except power and ground functions) at the end of DLC main cable.
This self-test function cannot determine open or short circuits in other adapter cables except CableDLC (26pin-16pin). Also, Wireless network functions and the VCI internal memory cannot be tested
using this function. If there are any open or shorted USB circuits, this self-test function cannot be
performed.
Purpose and Scope of Self Test (Semi-Test)

User’s Manual
22
Before performing the self-test function, connect the DLC Main Cable (P/N: GHDM-241000) between
VCI module and Self-test adapter. Then, connect the other side of Self-test Adapter to the OBD-∥
Connector on the vehicle as shown in Figure1.
Figure 1. Installation of the Self-test adapter
Self-test function is performed when the VCI module and terminal are connected by USB cable. When
the VCI module and information terminal are connected by wireless LAN, this self-diagnosis function
cannot be performed.
After installing the adapter, follow the instructions as indicated on the Self-Test screen located on the
Configuration menu.
