The Active Test function is used to access vehicle-specific subsystem and component tests. Available tests vary by vehicle.
During an active test, the tablet sends commands to the ECU to activate the actuators. This test determines the integrity of the system or part by reading ECU data, or by monitoring the operation of the actuators. Such tests may include switching a solenoid, relay, or switch, between two operating states.

Selecting Active Test displays a menu of test options. Available tests vary by vehicle. Select test from menu options. Follow the instructions displayed on the screen to complete test. Procedures and instructions vary by vehicle.


The functional buttons in the lower right corner of the Active Test screen manipulate the test signals. The operational instructions of Autel Maxisys Ultra are displayed in the main section of the test screen. Follow the on-screen instructions and make appropriate selections to complete the tests.

Tap the ESC functional button to exit the test when finished.
