5. Setup and Connection

Follow these general steps to set up your GODIAG Test Platform Cable. Specific connections may vary slightly depending on the vehicle model and the diagnostic task.

1. Identify the Correct Cable: Select the appropriate GODIAG GT model (e.g., GT112, GT111, GT110) based on the vehicle's IMMO generation and bus type (K-Line, CAN-Bus, UDS).
2. Connect to the Dashboard: The cable is designed for offline connection to the vehicle's dashboard. Carefully connect the specific connectors (e.g., green, blue) to the corresponding ports on the dashboard or IMMO module. Ensure all connections are firm and correct.

   

   

3. Connect to Diagnostic Device: Plug the OBD2 connector of the test platform cable into your compatible diagnostic device (e.g., HEX V2, VAS 6154, Obdstar, Lonsdor, AVDI, ZEDFULL, VVDI2, Key Tool Plus, X300 DP Plus, AUTEL).

   

4. Power Connection: Ensure the test platform cable receives power. This is typically supplied by the diagnostic device. Some setups may require an independent power source via the DC power input. The independent ignition switch (red button) can be used to control power to the dashboard.

   

6. Operating Instructions

6.1 Intelligent IMMO System Emergency Start Area Induction Detection

This feature helps identify the vehicle's key emergency start sensing area, which is useful if a smart key's battery is depleted.

1. With the test platform cable connected and the system powered, press the vehicle's start switch (or simulate ignition if working offline).
2. Bring the device's key identifier (the part with the light) close to different areas of the vehicle's dashboard or steering column.

   

3. Observe the key identifier light: If the light flashes or lights up, that area is the vehicle's key emergency start sensing area. Placing a smart key with a dead battery in this area can allow the vehicle to start.

6.2 Car IMMO Start and Start Key Chip Detection

This test verifies the functionality of the IMMO chip within a key and its communication with the IMMO system.

1. Ensure the test platform cable is correctly connected to the dashboard and your diagnostic device.
2. Initiate the IMMO test function on your diagnostic device's software.
3. Observe the key identifier light on the GODIAG cable:

• Flashes and then goes out: This indicates that the IMMO chip and the chip key are working properly and are synchronized.
• Flashes for a long time: This suggests that the chip key and the vehicle's IMMO system do not match. The chip key needs to be re-matched or programmed using your diagnostic device.
• Does not flash: This signifies a fault in the vehicle's IMMO system. Further diagnosis of the vehicle's IMMO system is required.

6.3 Data Read & Write (GT111, GT110, GT115, GT114)

For models like GT111 (CAN BUS 3rd Gen), GT110 (CAN BUS 4th Gen UDS), GT115 (MQB IMMO4), and GT114 (AUDI A4/A6), POGO PINs are integrated for advanced reading and writing of IMMO data.

1. Connect the POGO PIN interface to the corresponding points on the dashboard or IMMO module as instructed by your diagnostic device's specific procedures.
2. Use your diagnostic device's software to perform read/write operations for IMMO data.
3. Important: Always back up original data before attempting to write new data to prevent data loss or system corruption.

7. Maintenance and Care

Proper maintenance ensures the longevity and reliable performance of your GODIAG Test Platform Cable.

• Cleaning: Keep the cables and connectors clean and free from dust, dirt, and debris. Use a soft, dry cloth for cleaning.
• Storage: Store the device in a dry, cool environment, away from direct sunlight, corrosive chemicals, and extreme temperatures.
• Handling: Avoid bending, twisting, or pulling the cables excessively, as this can damage internal wiring. Handle connectors gently when plugging and unplugging.
• Inspection: Regularly inspect all cables and connectors for any signs of wear, tear, or damage. Do not use damaged cables.
