Active Test
The Active Test function is used to access vehicle-specific subsystem and component
tests. Available test vary by manufacturer, year, and model, and only the available tests
display in the menu.
During an active test, the tester outputs commands to the ECU in order to drive the
actuators. This test determines the integrity of the system or parts by reading the
engine ECU data, or by monitoring the operation of the actuators, such as switching a
solenoid, relay, or switch, between two operating states.
Selecting Active Test opens a menu of test options that varies by make and model.
Selecting a menu option activates the test. Follow all screen instructions while
performing tests. How and what information is presented on the screen varies
according to the type of test being performed. Some toggle and variable control tests
display Active Test Controls at the top of the screen with data stream information below,
or vice versa.
