Activating components/functions

Activation of components
Using this facility, a number of components can be activated to check their function. The following components can be activated:

Glow plug
Activating the glow plug.
Important! This function should be activated for no longer than 10-20 seconds.

Heater fan
Activating the heater fan.
A "buzzing" noise is heard from the heater fan when it is activated.

Fuel pump
Activating the fuel pump.
A "buzzing" noise is heard from the fuel pump when it is activated.

Warning! The fuel pipe shall only be filled when replacing the pipe. If you fill with fuel for too long, there is a risk of smoke development or heater damage. However, it is necessary to fill the pipe when replacing the fuel pipe as the control unit only permits 3 heater start attempts. In diesel engines, it shall take a maximum of 8 minutes to fill up with fuel when replacing the pipe. In gasoline engines, it shall take a maximum of 8-10 minutes to fill up with fuel when replacing the pipe.

Water pump
Activating the water pump.
A "buzzing" noise is heard from the water pump when it is activated.

Heater
Activating the heater.
In case of too low battery voltage or if the heater is in a state that prohibits activation, the heater will abort the activation. In order to enable start of the heater itself, battery voltage shall be normal, coolant temperature must be lower than +96 °C, and the heater's post-run/stop sequence must be completed. There must also be enough fuel in the tank.

Caution! If the heater or other components are not activated, try closing down the activation window and then starting the activation again with the symbol for VCT2000.

Component supply voltage
Activating the relay that provides supply voltage to the water pump, fuel pump and heater fan.
