3360833 - E3030 HEATED REAR WINDSCREEN AND DOOR MIRROR DEFROSTING - Description

Description

In the case of poor visibility, it is possible to activate demisting of the rear window, door mirrors and windscreen washer nozzles.

The heating resistances for these components absorb a considerable amount of energy and they are therefore checked and deactivated after a certain period: the defrosting is timed, according to the following logic, managed by the Body Computer:

  • ignition ON (INT/A);
  • activation signal from the relevant button, located on the climate control system control panel.
In these circumstances the resistances remain supplied for a maximum of 20 minutes, then the power supply is cut off.

The power supply is also cut off under the following conditions:

  • ignition in OFF position
  • deactivation signal from the relevant button;
  • battery voltage below 8.5 V
  • after the first 10 minutes operation, if the engine speed is below 1000 rpm.
When the demister is on, a warning light on the climate control system control unit is activated.
