What is Active Test &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 v 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.

What is ECU Coding?

The advanced coding function is used to re-flash the vehicle control modules, which allows you to update the computer software on the vehicle to the latest version, as well as to reprogram adaptive data for certain components after making repairs or replacements, providing solutions for the issues of drivability, fuel efficiency, power loss, fault codes, durability of mechanical parts etc. But please note, ecu coding are NOT universal for all vehicles, please check compatibility with VIN number before purchase.
