Step 3: Select “read ISN”, This function requires networking, please ensure that the network is normal. There is a certain risk in reading the engine ISN code, and programming is required, need to ensure that the power supply voltage is stable and exceeds 13V.

Step 4: The device will detect whether the current engine version supported to read ISN. If the current version support, it will jump to the payment interface.

Step 5: After making the payment, click OK. The device back up the coding file then download the configuration file. (Make sure the network is working when downloading files.)

Step 6: Downloading the configuration file complete, Click “ok” to enter the programming operation, which is divided into five parts. It takes about 50 minutes. Some models may take longer.
