①Check the power supply from the vehicle battery
Using a multi-meter, please check condition of the vehicle battery first. Recharge or replace
the battery as necessary.

Please check for power supply from the vehicle side Data Link Connector (mostly located under
left side of the dash.) Turn the Ignition ON and check for voltage at Pin #4 or #5 (Ground) and
#16 (Battery positive) by using the multi-meter.
If power supply from the vehicle battery seems flawless, go to step 2 to continue diagnosis.
*Note: Some vehicles do not provide power through the DLC. G-scan3 may require an external power supply other than
just the main DLC cable, G-Scan3 can receive power by additionally connecting the Cigar Lighter cable.

③Check the battery charging circuit voltage
*When measuring the charging voltage, keep the battery connected.
If Main board does not detect battery, recharging circuit is not enabled and thus, powering on and
charging the battery is not available.
Using the Multi-meter, check the voltage of the battery charging circuit at the terminal shown
above. Measure cell voltage at each same numbered pin for positive and GND
Normally average voltage should be around 3.7~ 4.2 V
The charging voltage can be as low as 3.7V when the battery is fully discharged.
14
If the charging voltage is lower than 3.7V, replace the Main Board.
If the battery cannot be charged, go to Step 3.

②Self-Test <Step A>
Through this Step A test procedure, G-Scan3 tests the internal circuits used for the communication
protocols such as ISO9141, ISO9141-2, KWP2000, Melco (Old Mitsubishi).
Circuits for CAN-Bus, J1850 (American cars in general) and some specific communication protocols
are not tested, therefore passing this test without error should not be interpreted as representing that
G-Scan3 is not defective.
If the result is “No Error found”, proceed to the Step B test procedure described in step 3.
If the result is “Error Found”, replace the VCI Board.
When VCI module is replaced, the new serial number contained in the new VCI module is copied to the
main board automatically.
*Register the new serial number to SMS server and put the new serial number sticker to the base unit.
