Start Diagnostics

The diagnostic system comprises two main components: the display tablet and the VCI connector.

Display tablet: Acts as the central processor and monitor for analyzing vehicle data and displaying test results.
VCI connector: Serves as the vehicle communication interface device for accessing vehicle data (applicable to 12V passenger vehicles).

The following illustrates how the display tablet works with the VCI connector:

Diagram Description: A schematic showing the VCI Connector connecting to the Vehicle's DLC (Data Link Connector) via a cable. The VCI Connector also communicates wirelessly or via cable with the Display Tablet. The Display Tablet is connected to the Internet. The DLC is shown as a standard 16-pin connector, with a diagram indicating its typical location in a car's dashboard, often near the steering wheel.

1 Preparation & Connection

Switch the ignition **OFF**.
Ensure the vehicle battery voltage is between **9-18V**.
Throttle should be in a closed position.

2 Connection

Follow these steps:

For vehicles with an OBD II management system: Plug the VCI connector directly into the vehicle's DLC or use the OBD II extension cable.
For vehicles without an OBD II management system:
- a. Select the corresponding non-16pin connector.
- b. Plug the non-16pin end of the connector into the DLC socket. Connect the other end to the OBD I adaptor and tighten the captive screws.
- c. Connect the other end of the adaptor to the VCI connector.
- d. To supply power to the OBD I adaptor:
  - A. Battery Clamps Cable (optional): Connect one end to the vehicle's battery and the other end to the OBD I adaptor's power jack.
  - B. Cigarette Lighter Cable (optional): Connect one end to the vehicle's cigarette lighter receptacle and the other end to the OBD I adaptor's power jack.
- Switch the ignition **ON**.

3 Start Diagnostics

Diagram Description: A flowchart illustrating the diagnostic process. It starts with tapping 'Diagnose', followed by 'Select vehicle', and then 'Select software version and tap "OK"'.

Notes:

To start a diagnostic session, the VCI connector must be activated and diagnostic software downloaded. Refer to Section 3 "Register & Update" in this Quick Start Guide.
After use, remove the VCI connector from the DLC and re-insert it into the VCI slot to prevent loss.
