What it can help you investigate
Available diagnostic functions depend on your selected tractor and the information its ECM makes available. Use the tool to identify electronically reported concerns and choose the next inspection—not as a substitute for proper mechanical repair.
| System area | How the scanner can help |
|---|---|
| Engine & transmission | Read supported active and logged faults across engine and transmission systems, then review the code description before checking the cause. |
|
Fuel, air & turbo systems Where supported |
Use reported DTCs and available data to investigate concerns involving fuel rail pressure, boost pressure, intake temperature and throttle position. |
|
Electrical, sensors & communication Where supported |
Check electronically reported battery-voltage, sensor and CAN communication concerns as made available by the tractor's systems. |
|
Emissions & after-treatment Where fitted and supported |
Review available EGR, DPF, DEF and after-treatment fault information on compatible machines equipped with those systems. |
See supported live data, not just a fault number
A code tells you where to begin. Live values can help you decide what to inspect next. Depending on what your selected machine supports, the scanner can display information such as engine RPM, coolant temperature, oil pressure, fuel rate, boost pressure, intake-manifold temperature, throttle position, battery voltage, engine hours, fuel level, vehicle speed and transmission gear position.
|
Active & logged codes Review current faults that can trigger warnings or reduced performance, as well as stored diagnostic information available from the system. |
Clear code guidance After the underlying condition has been corrected, follow the tool's clearing procedure for the detected code. |
Made for a practical diagnostic workflow
| 1 | Select your exact New Holland model family and year. Confirm the selectable fitment before you add the scanner to cart. |
| 2 | Connect, read and understand the result. Use the code definition and available live data to direct your next diagnostic check. |
| 3 | Correct the cause before clearing the code. Diagnostics should guide a proper repair, not replace it. |
