4.8 Active Test
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 toggling a solenoid,
relay, or switch, between two positions.
Selecting Active Test displays a menu of test options. Available tests vary by vehicle.
Select test from the menu options. Follow the instructions displayed on the screen to
complete the test. Procedures and instructions vary by vehicle.
