5.2.3.5 Actuation Test
This option is used to access vehicle-specific subsystem and component tests.
Available test vary by vehicle manufacturer, year, and model.
During the actuation test, the X-431 HTT handset outputs commands to the ECU
in order to drive the actuators, and then determines the integrity of the system or
parts by reading the ECU data, or by monitoring the operation of the actuators,
such as switching a injector between two operating states.
Simply follow on-screen instructions and make appropriate selections to
complete the test. Each time when an operation is successfully executed,
“Completed” displays.
