Diagnostic tools are used to check vehicle electronic systems, control units, sensors, fault codes, service functions and other components. This equipment helps identify the cause of a problem faster and supports more accurate repair or maintenance decisions.

This section includes diagnostic equipment for passenger cars, commercial vehicles, heavy-duty vehicles, motorcycles, electric vehicles and specialized machinery. The equipment is suitable for vehicle service centres, automotive electronics specialists, tyre services, fleet operators and private users who need to check vehicle systems.

Vehicle diagnostic tools for different service tasks

The right diagnostic equipment depends on the vehicle type and the work being carried out. Basic tasks may only require fault code reading and clearing, while more advanced work may require service functions, active tests, coding, programming, TPMS work, ADAS calibration or access to heavy vehicle systems.

Passenger cars, heavy-duty vehicles, motorcycles and electric vehicles have different diagnostic requirements. Before choosing a specific device, it is important to check vehicle coverage, software, required functions, adapters, cables, updates and the intended type of use.

Diagnostic equipment groups

• Car diagnostic equipment for passenger cars, commercial vehicles and regular service diagnostics.
• Diagnostics of specialized and heavy vehicles for trucks, buses, trailers, tractors, construction machinery and other specialized equipment.
• Motorcycle diagnostic equipment for motorcycles, scooters, ATVs and other motorcycle-related equipment.
• Oscilloscopes, endoscopes and testers for checking electrical signals, sensors, components and hard-to-reach areas.
• Programming equipment for control units, keys, immobilisers, coding and software-related work.
• Battery service equipment for electric car batteries for checking EV and hybrid vehicle batteries and high-voltage systems.
• Add-ons, updates and licenses for diagnostic software, databases, adapters, cables and accessories.

Diagnostic tool functions vary by manufacturer, software, vehicle coverage and configuration. Some devices are intended for everyday fault code reading and service functions, while others are better suited for advanced electronics diagnostics, programming, heavy-duty vehicles or specialized machinery.
