Active Test
The Active Test function is used to access vehicle-specific subsystem and
component tests. Available tests vary depending on the 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 on-screen
instructions while performing tests. The content and pattern of the on-screen
information vary 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.
