ECU Coding with Launch X431 PRO3 APEX

The ECU coding function of the Launch X431 PRO3 APEX allows selected control unit functions and parameters to be configured on compatible vehicles.

Following repairs or replacement of supported components, relevant adaptive data and control unit parameters can be relearned or coded where supported by the vehicle.

Active Tests & Bidirectional Control

Active tests are an important tool for targeted troubleshooting. Instead of only reading fault codes and live data, the diagnostic scanner can directly command supported components and actuators through the corresponding control unit.

The Launch X431 PRO3 APEX supports active tests and bidirectional control on compatible vehicles.

This allows the diagnostic system to communicate with control units and command supported modules or components to perform specific tests and functions.

Examples of Active Tests

• Activate and test relays
• Activate fuel injectors
• Test ignition coils

Available active tests depend on the vehicle manufacturer, model, model year and installed control unit.

Built for Professional Workshops and Automotive Technicians

With its combination of comprehensive vehicle diagnostics, extensive service functions, ECU coding and bidirectional control, the Launch X431 PRO3 APEX professional diagnostic scanner is particularly suitable for workshops and automotive professionals who work with multiple vehicle brands and need one central diagnostic platform.

The actual range of available functions may vary depending on the vehicle manufacturer, model, model year, engine configuration and installed control units.
