2.2. Bi-directional Control (Active Tests)

Bi-directional control enables the scanner to send commands to vehicle components to test their functionality, such as activating the radiator fan, modulating the throttle, or operating windows and lights. This feature assists in quickly identifying malfunctioning components.

1. After performing an all-system diagnostic, navigate to the "Active Tests" or "Bi-directional Control" section for the relevant system.
2. Select the component you wish to test and follow the on-screen instructions to activate or deactivate it.
3. Observe the component's response to diagnose potential issues.

2.3. ECU Coding

ECU Coding enables advanced vehicle customization and procedures for module replacement. This includes online coding for specific brands (VW/Audi/Skoda/Ford/Lincoln/Mazda), activating or deactivating hidden functions, personalized modifications, and programmable module installation.

1. Access the "ECU Coding" function from the diagnostic menu for supported vehicles.
2. Follow the guided procedures to perform the desired coding operations. Exercise caution as incorrect coding can potentially affect vehicle functionality.
