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.
During an active test, the tablet sends 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.
The function buttons at the lower right corner of the Active Test screen manipulate the
test signals. The operational instructions are displayed on the main section of the test
screen. Simply follow the on-screen instructions and make appropriate selections to
complete the tests. Each time when an operation is successfully executed, message
such as “Command Finished”, “Activation Successful”, or something similar displays.
Tap the ESC function button to exit the test when finished.
Special Functions
These functions perform various component adaptations, allowing you to recalibrate or
configure certain components after making repairs or replacement.
