Active Test / Bi-Directional Control
Active Test or Bi-Directional Control is a very useful function. This function allows the user to send commands to the vehicle's control modules and request specific information from them. This feature is particularly useful in diagnosing and repairing problems in a vehicle's systems.
With Active Test or Bi-Directional Control, you can initiate commands to perform specific tests and functions. For instance, you can request information from the powertrain control module to check the vehicle's emissions system. The module responds by sending the information back to the scan tool for display. Additionally, you can actuate relays, injectors, coils, or perform system tests, and more, to diagnose and repair issues with the vehicle.
The ANCEL X7 bi-directional scan tool supports the control modules of many different systems within a vehicle. This includes systems such as mirrors, sunroofs, door locks, radiator fans, horns, and lights, among others. By using this tool to actuate these systems, you can test the functionality of the modules and identify any issues that need to be addressed.
Overall, the Active Test or Bi-Directional Control function available in the ANCEL X7 bi-directional scan tool is a powerful diagnostic tool that enables the user to diagnose and repair issues with a vehicle's systems more efficiently and effectively.
