Why is truck diagnostics becoming more software-led?
Heavy-duty vehicles now rely on multiple electronic systems that must work together during normal operation and maintenance.
Engine controls, emissions equipment, braking systems, safety electronics, and body-control functions increasingly require software-supported service procedures. This raises the importance of tools that can move beyond identifying diagnostic trouble codes.
Noregon positions JPRO around guided diagnostics, bi-directional commands, aftertreatment diagnostics, and preventive maintenance functions. Jaltest similarly positions its commercial vehicle platform around multi-brand and multi-system diagnostics covering trucks, buses, trailers, and commercial pickups.
The result is a changing purchasing criterion. Workshops are looking for tools that can keep technicians within one service workflow rather than requiring repeated switching between disconnected platforms.

The market is increasingly defined by workflow completion. Broad vehicle coverage has value, but technicians also need dependable bi-directional tests, aftertreatment functions, parameter changes, and programming support.
Why does multi-brand diagnostic software lead the market?
Multi-brand diagnostic software is estimated to account for 31.2% of the market in 2026.
Independent workshops and fleet service centers often maintain vehicles from several manufacturers. A multi-brand platform can reduce the need for separate diagnostic environments and help technicians handle different truck systems from one interface.
Noregon's JPRO platform emphasizes guided diagnostics and bi-directional commands. Jaltest CV provides multi-brand commercial vehicle coverage across trucks, buses, trailers, and commercial pickups.
This positions multi-brand software as more than a scanning tool. It becomes part of the technician's productivity workflow.
The value proposition is especially strong where service teams need to diagnose multiple systems during the same repair visit.
Why does fault diagnostics remain the largest application?
Fault diagnostics holds approximately 27.8% share in 2026.
Finding and isolating faults remains the starting point for many truck repair processes. A technician may need to investigate an engine fault, emissions issue, brake-system problem, or body-control malfunction before proceeding to programming or configuration.
Noregon highlights rapid diagnostics and guided service workflows, while Bendix positions its ACom diagnostic software around access to brake and safety electronic systems.
The expanding number of electronically controlled systems is increasing the depth of this diagnostic process. Basic code reading is no longer sufficient for many advanced repair jobs.
What is driving market growth?
The market is benefiting from the growing electronic content of commercial vehicles and the continued need to maintain trucks throughout their operating lives.
OICA data cited in the supplied market material shows global motor vehicle production reached 92.5 million units in 2024. A larger and increasingly electronic vehicle population creates recurring demand for professional diagnostic equipment and software.
Key growth factors include:
• Rising ECU density: More electronically controlled systems increase diagnostic requirements.
• Software-dependent service: Programming and parameter configuration are becoming routine parts of commercial vehicle maintenance.
• Multi-brand fleet requirements: Mixed truck fleets need tools capable of supporting different manufacturers.
• Aftertreatment complexity: Emissions-related systems require deeper diagnostic and service functions.
• Safety-system electronics: Brake and safety systems create additional demand for specialized diagnostic access.
• Standardized interfaces: RP1210-compliant adapters support communication between diagnostic applications and vehicle systems.
RP1210 is particularly relevant to multi-brand service environments because standardized communication layers can help connect diagnostic software with different truck systems.
What could constrain market adoption?
Tool fragmentation remains a major challenge.
A workshop may require different software environments, adapters, subscriptions, or manufacturer-specific functions depending on the truck and subsystem being serviced.
RP1210 helps standardize access, but programming and diagnostic coverage can still differ by vehicle brand, electronic system, and application.
This creates additional training and equipment costs for workshops. Fleet operators also need to consider whether a diagnostic platform can complete the required repair workflow rather than simply identify a fault.
The competitive advantage therefore increasingly rests on coverage depth, reliability, programming capability, and ease of use.
