Description of Power Supplying Method
Power supplying with the DLC cable
The vehicle of which diagnosis connector terminal is the 20-Pin
connector or which is satisfying the OBD-II communication regulation
can be supplied the electric power from the DLC cable without any
additional power line.
Note:
The DLC connector, in general, is located at the lower part of the
driver’s front panel. This location may be different somewhat, please
check the correct location before connecting.
From the cigarette lighter in the cabin
Using the cigarette lighter power cable purchased as a basic item with
the G-scan, the electric power can be supplied.
Note:
When using the cigar cable, the power will be cut during ignition of the
engine. Therefore, for the G-scan without rechargeable battery, the
power will be OFF. If your G-scan does not have rechargeable battery
and you diagnose vehicle relating to the ignition of engine, use other
power supplying method.

engine room.
Š Connect correct power lines to the battery terminals.
From the AC/DC adapter
Using the AC/DC adapter purchased as a basic item with the Gscan, the electric power can be supplied to the G-scan.
When updating the G-scan, use the AC/DC adapter for supplying
stable power to the G-scan.
Warning
Use only the AC/DC adapter supplied by GIT for the G-scan. GIT
has not responsibility for the damage by different kinds of AC/DC

Self Test Adapter
Basic Use of G-scan
Module NO: A-02-006
The self-test functions are used to check the Main DLC cable (P/No:
G1PDDCA001) and specific related circuits. Not all G-scan circuits are
checked with the self-test functions.
Purpose and Scope of Self Test (Semi-Test)
Basic operation of the self-test function is the loop-back theory.
Loop-back theory is verification between sent data from the G-scan
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.
