If you don't see accurate or component-specific information for your vehicle, please call us at (989) 839-4877 and a technical specialist will assist you with your questions..
What is the difference between JPRO Fleet PC Software vs. the Nexiq PC Software?
Loaded on a computer by itself, the Nexiq PC software gives no fault information at all. All it is is a portal that allows you to load factory OEM Software on your PC and communicate with the truck.
The JPRO Fleet Diagnostics software is user friendly, it displays/erases SAE (generic) and OEM Engine, ABS, Transmission & Chassis Codes. The screen controls and menus are the same no matter which factory software is loaded on your computer. For example, if you are diagnosing a truck using Mack factory software, then disconnect and connect to another truck and use your factory Cummins software, your computer screen will look and act the same. You will not be able to tell the difference between working with Mack factory software and Cummins factory software. In addition, all of the reports you print out will have the same format (look and feel) irregardless of which factory software was used during data collection. This means that you only need to know how to navigate within the JPRO software. You will not need to learn how to navigate around and use Mack software, or the Cummins, software, or the CAT ET software, or the Detroit Diesel software. No matter which factory software you have turned on, you will always see the same screens, menus, options, reports and parameter lists. This single user interface saves a lot of aggravation and wasted time struggling to find out how to use all the switches and controls in each factory software loaded on your computer.
Is JPRO Fleet Diagnostics capable of parameter adjustments?
No, JPRO Fleet Diagnostics is a diagnostic tool only.
Can JPRO Fleet Diagnostics perform vehicle tests such as cylinder cutouts?
Certain OEM applications have the ability to perform vehicle tests and JPRO Fleet Diagnostics provides the ability to easily launch these applications. Vehicle tests are OEM-specific functions.

Can JPRO Fleet Diagnostics adjust user-configurable parameters such as road speeds or idle shutdown settings?

If I have OEM software why do I need JPRO Fleet Diagnostics?
