2. Turn on the ignition.
3. Select the "Immobilizer" function from the diagnostic tool menu.
4. Follow the prompts on the diagnostic tool screen to read the current immobilizer code.
5. Enter the new immobilizer code and confirm.
6. Turn off the ignition and wait for 30 seconds.
7. Turn on the ignition again. The engine should start and run normally.
