It’s not enough to just install the app. To ensure a good truck diagnosis, it’s important to do a correct configuration right from the start.

2. Activate Bluetooth or Wi-Fi, depending on the type of scanner.

If the code indicates something more serious, be sure to do a full inspection of the truck.
