Bi-directional control :

Bi-Directional Control capability and is capable of performing Active Tests to access vehicle-specific subsystems and component tests. The tester outputs commands to the ECU to drive the actuators in order to determine the integrity of the system or parts by reading the ECU data, or by monitoring the operation of the actuators .For example , X431 PRO TT have the ability to actuate relays, injectors, coils, or perform system tests, etc. Also it will actuate solenoids valve and actuators for active testing to identify the error easily moreover. The bidirectional functions are quite extensive. even open an e.g.r. valve and seeing the difference in idle response and oxygen sensor voltage. Please note: Active tests are NOT universal for all vehicles, check compatibility with VIN number before purchase. Active tests vary depending on the manufacturer, year, and model, and only the available tests display in the menu.
