Diagnostics And Services: Activations
Wit this service it is possible to trigger (activate) the components that are connected to the control module. Examples of components are:
- Relays
- Solenoids
- Lock motors
- Damper motors
- Signals to other control modules.
If a malfunction is detected, diagnostic trouble code is stored and emergency functions or modes, etc. are activated to "protect" the system, the control module can prevent activation.
Depending on the system, the control module or diagnostics tool can perform activations in different ways, for some the component is activated according to a certain pattern, e. g., OFF, ON, OFF, ON, OF, ON, etc. in a sequence.
For other systems, the component is activated, e. g., ON, and remain on until the activation is stopped.
