New Holland diagnostic tool – Professional vehicle diagnostics for construction professionals

Anyone who works with New Holland construction equipment knows that quality, precision, and reliability are crucial in every project. Ensuring these machines operate efficiently over the long term requires the right tool – a specialized New Holland diagnostic tool .

Our diagnostic tools are precisely tailored to the electronics of modern New Holland machines. They provide complete access to the engine control, hydraulics, transmission, and comfort systems. Whether troubleshooting, calibration, or service adjustments – with the right diagnostic technology, your fleet will always be operational.

Why a New Holland diagnostic tool is essential

Modern New Holland construction machines operate with highly complex electronic systems. Without a suitable diagnostic tool, professional maintenance is virtually impossible.

A New Holland diagnostic tool offers brand-specific access to all relevant control units. It analyzes stored error codes, displays live data, and allows system adjustments that go far beyond the standard. This allows you to identify problems early – before they lead to costly downtime.

Unlike universal devices, a brand-specific diagnostic device operates at a deep system level. It uses the exact protocols New Holland installs in the vehicle. This saves time, increases diagnostic quality, and ensures precise results – whether in the workshop or on the construction site.

Functions of our New Holland diagnostic devices

Read and delete error codes

A key element of every New Holland diagnostic tool is the ability to quickly and reliably read error codes from all relevant control units. Whether it's the engine control unit, transmission control unit, hydraulic system, or secondary electronic functions – the tool accesses all installed systems and provides a structured error diagnosis.

The displayed codes are not simply presented as a sequence of numbers, but are accompanied by a clear error description. This allows even less experienced users to understand exactly where the problem lies. After repairs or replacement of defective components, the error codes can be erased directly using the diagnostic tool.

Resetting the control unit is especially important when warning lights in the cockpit remain active even though the problem has already been resolved. Targeted erasure of the error log not only resets the display in the cab but also restarts monitoring of the affected system – an essential step for accurate maintenance documentation and trouble-free continued operation of the machine.

Calibrate and program control units

New Holland diagnostic tools offer far more than just error detection – they also enable active editing and programming of control units. When a new control unit is installed after a repair or a sensor needs to be replaced, physical replacement alone is not enough. The component must be identified, configured, and often calibrated within the system.

Our diagnostic tools make these steps easy. The device automatically detects new components or offers the user specific menu items for programming. This is particularly relevant for electronic hydraulic valves, axle sensors, or transmission control units – components frequently used in New Holland construction equipment .

Software versions or updates can also be adjusted via the device, provided they are available. Workshops benefit particularly from this: They no longer have to return machines to the manufacturer or wait for OEM technicians. Instead, they can perform repairs and software adjustments independently in a single step – efficient and time-saving.

Live data and system monitoring

A powerful New Holland diagnostic tool not only provides historical error messages but also displays real-time information on the machine's current performance. This includes a wide range of technical parameters: engine speed, oil temperature, injection pressure, hydraulic flow, battery voltage, exhaust gas recirculation, and much more.

This live data is indispensable in practical applications – for example, when symptoms occur for which there is no error code (yet). A jerking engine, a delayed hydraulic system, or uneven performance can be analyzed directly. Instead of replacing parts on suspicion, technicians can use data to specifically narrow down the source of the problem.

Live data also enables monitoring of machine behavior under load, in various operating conditions, or in comparison to reference values. This feature is particularly helpful during test bench runs, demonstrations, or the return of used machines – it creates transparency and technical reliability.

Service functions and maintenance management

New Holland diagnostic tools actively support maintenance planning and execution. The device software allows you to read, reset, or redefine service intervals—for example, after oil changes, filter replacements, or maintenance steps with follow-up time.

This not only helps with compliance with statutory inspection intervals, but also ensures clear internal maintenance documentation. Service reports can be created and exported via the diagnostic device – ideal for workshops, contractors, or fleet operators who require documentation for clients or insurance companies.

In addition, many devices offer additional functions such as testing individual actuators (e.g., fans, valves, pumps) or controlling system components for targeted testing. Such actuator tests make the difference between a guess and a well-founded technical analysis. Overall, maintenance becomes a plannable, transparent process – entirely in keeping with modern, cost-effective machine support.

Diagnostic use directly on the construction site or in the field

A New Holland diagnostic tool demonstrates its strengths not only in the workshop, but also directly in mobile applications. Many New Holland construction machines are used outdoors – for earthmoving, road construction, or agriculture.

When a warning light suddenly appears, every minute counts. Our diagnostic tools are robust, compact, and designed for off-road use. They work reliably in dusty, wet, and shock-prone conditions—and enable a complete on-site analysis.

Thanks to battery operation and wireless connectivity, they can be used even remotely. Error codes can be checked immediately, live values ​​analyzed, or control units reset – without a visit to the workshop or extended downtime.

For companies with tight timeframes, this is a clear competitive advantage. You react faster, minimize downtime, and maintain control of your New Holland construction equipment at all times.

Workshop advantages through targeted diagnostic solutions

Specialized workshops that regularly service New Holland machines benefit greatly from a brand-specific diagnostic tool. Unlike universal tools, a New Holland diagnostic tool offers in-depth access to vehicle-specific systems.

This enables precise troubleshooting, more efficient repair processes, and higher customer satisfaction. Control units can be directly trained, software versions can be compared, and settings can be precisely documented – all without complicated detours.

Another advantage: One device can often cover multiple models simultaneously. This reduces the number of devices used, lowers training costs, and saves space in the workshop.

Thanks to regular updates, you'll stay up to date even with newer model generations. This means your service is well prepared for the future – for all common New Holland construction machines .
