4.1.3.7 Active Tests
Active Tests also known as Actuator Tests are bi-directional diagnostic tests on vehicle systems
and component. The tests let you to use the scanner temporarily activate or control a vehicle
system or component, and when you exit the test, the system/component returns to normal
operation.
Some tests display a command to the operator. For example, if “Press Brake Pedal” displays, the
operator has to press and hold the brake pedal and then continue. The sequence, number, and
type of tests are dictated by the control module.
On some systems, the actuator tests cannot be restarted until the ignition key is switched off for
some time. Alternatively, briefly start and run the engine, shut down, turn the ignition to the run
position, then re-initiate the actuator tests.
Typical menu options may include:
● Selective Active Test
● Sequential Active Test
IMPORTANT
The tests activate a component, but they do not check if the component is working correctly.
Make sure the components to be tested are in good condition and correctly mounted.
NOTE
Available tests depend on the control module under test and the vehicle itself.
