Connecting to your vehicle for the first time

If you have just received your diesel laptop and need help on how to use your diesel diagnostic laptop for the first time, then this is the page you need to read.

1. You need to connect your laptop to your truck and the laptop with the usb cable. Make sure your truck is turned on with the key in the ignition.

2. Select the correct program to use with your engine. Below explains which program (icon) you should use on depending on your vehicle.

J pro is universal and will work with all heavy duty semi truck engines and is very user friendly

For more direct programming you can use the original programs depending on your engine, transmission or brake system.

If there are 2 options available you can use either one


To use J pro connect to your truck or Diesel engine correctly via the usb link cable to the laptop and the adapter to the vehicle. Then click connect on the top, and you are good to go.

J pro will work with all engines but for the original dealer programs these are what you will need to use
