Step 2: Pre-Process the BDC2 Module

Removing the BDC2 module is crucial for pre-processing and subsequent key programming.

1. Carefully remove the BDC2 module from the vehicle.
2. Using the VP100 BDC Adapter, follow the wiring diagram provided in this guide.
3. Solder the chip marked in the diagram to pin 2, ensuring that the EPP2 GND of the adapter is connected correctly.
4. Connect the boot line from the BDC Adapter to the appropriate wire as indicated.

Generating the Dealer Key

Once the BDC2 module is pre-processed, you can generate a dealer key.

1. Reinstall the BDC2 module back into the vehicle.
2. Utilize the VP100 to commence the key generation process.
3. Follow the on-screen instructions provided by the VP100 for a seamless experience.

Key Matching & Verification

After generating the key, it’s time to match and verify its functionality.

1. Place the newly generated key near the induction coil located on the right side of the steering column.
2. Press and hold the vehicle’s start button for 20 seconds to initiate the pairing process.
3. Once matched, test the key to confirm it operates correctly (lock/unlock, start the vehicle, etc.).

Final Steps and Troubleshooting

If at any point you encounter issues during the key programming process, consider the following troubleshooting tips:

• Double-check all connections and soldering work for any errors.
