Frequently Asked Questions:

Can I upgrade the laptop? Yes, we offer upgrades to Surface Pro Tablets with Armor, along with Panasonic FZ55 Toughbooks.

Why do you include the universal cable and the engine specific cables? Think of the universal cable as a "build a cable". The software will tell you which specific pins to place on this cable, which you then attach to the diagnostic port. This can be a bit of a hassle, especially if you are out in the elements or lose a small piece of the kit. The molded, engine specific cables are more durable and allow quicker connection time.

Does this kit include all the cables I will ever need? The universal cable can be used in most situations, and the engine specific cables you receive are the most common. There are other cables available to purchase.

Is there a required annual fee? No. After 12-months you will still have all of your functionality. However, you will not receive updates, support, or repair information. If you want these things, you need to purchase a Jaltest Marine Renewal.

Can I install the software on more then 1 computer? Yes, you can have the software installed on up to 3 computers. However, you can only use one computer at a time.

Does this tool require Internet to work? No, you do not have to be on the Internet to use this program. However, you must have Internet in order to use the following functions: Troubleshooting by Symptom, Troubleshooting by Fault Code, Vehicle Technical Data, and Technical Releases. We do have a solution that allows your laptop to access the Internet without any additional devices. Learn more about Diesel Laptops LTE Network here.
