Heated Windscreen

Operation of the heated windscreen is controlled by the CCU and a non latching switch on the centre console. The switch contains a LED which illuminates while the heated windscreen is on. Power for the heater elements is supplied by a relay, on the inboard side of the E-box, controlled by the CCU. Two fuses next to the relay provide electrical protection for the heater elements.

When the heated windscreen switch is pressed, the CCU energises the heated windscreen relay, provided the engine is running, to connect a battery power feed to each of the heater elements. The feed to the RH heater element also provides the power feed to illuminate the LED in the heated windscreen switch.

The CCU de-energises the heated windscreen relay after approximately 5 minutes, when the switch is pressed again, or if the engine stops.
