Big trucks keep the world running. They move food, fuel, parts, and everything you can think of. When a truck stops working, everything stops. Deliveries get late. Businesses lose money. Drivers get stuck on the road. That is why mechanics need strong tools. Tools that find problems fast. Tools that show what is wrong before something breaks. Tools that keep trucks moving. JPro software is one of those tools. It helps mechanics read truck data, find issues, and fix things faster. Instead of guessing, they see real numbers. Real codes. Real problems. Clear and simple.

What JPro Can Do

It shows all the faults from all systems. Right away. No jumping between screens.
Fault Code Help
Finding a code is one thing. Understanding it is another. JPro helps with both.
For each fault, JPro shows:
• What the code means
• What system it comes from
• Possible causes
• Steps to fix

This saves hours. Mechanics do not guess. They follow clear steps.
Live Data Streams
Open the live data tab. Watch sensors in real time.
You can see:
• Temperatures
• Pressure

You can graph values. Compare sensors. Catch issues that only show while the engine runs.
Aftertreatment Tools
