III. Actuation Test ---------------------------------
- The actuation test is a very helpful function that temporarily activates
or stops a certain actuator such as an injector, a motor or a solenoid
by force, so that the user can evaluate the system's condition or the
part’s normal operation by observing its reaction
- Signals from various sensors are input to a control unit, and the
actions are taken by controlling to actuators. Sensors and
actuators are causes and effects in a control system.
- While the data stream function is useful to observe if the sensors are
working properly and the control unit is collecting correct data from
the sensors without problem, the actuator test is helpful to examine if
the actuators are working in normal conditions and the control unit is
commanding proper control over the system.
- Some of the cars such as Nissan or Toyota provide even more
advanced actuation tests by letting the user observe the reaction of
overall control system when manually adjusting the sensor input
values.
