It is suitable for diagnostics on cars, vans, trucks, buses, trailers and a wide range of commercial and specialist vehicles, subject to vehicle and software coverage.

Key Features

Full-System Professional Diagnostics

Access and diagnose available electronic control modules across the vehicle rather than being limited to basic engine fault codes.

Functions can include:

• Read and clear diagnostic trouble codes (DTCs)
• View live data
• Freeze-frame information
• ECU identification and version information
• Actuation and active tests
• Adaptations and relearns
• Component matching
• Coding and configuration
• Module initialisation
• System reset procedures
• Pre-scan and post-scan
• Auto VIN identification

The exact functions available depend on the vehicle make, model, year, ECU and software coverage.

Bi-Directional / Active Testing

The PRO3S+ SmartLink HD can communicate with compatible vehicle control modules and perform bi-directional tests, allowing technicians to command supported components and verify their operation.

Depending on the vehicle, examples can include testing:

• Cooling fans
• Fuel pumps
• Injectors
• EGR systems
• Throttle systems
• Solenoids
• Relays
• Lights
• Windows
• Door locks
• HVAC components
• Other electronically controlled systems

This can help technicians move beyond simply reading fault codes and perform more effective fault diagnosis.

ECU Coding & Advanced Programming

The PRO3S+ SmartLink HD supports advanced ECU functions on compatible vehicles, including:

• ECU coding
• Online coding
• Component matching
• Module replacement procedures
