INTERIOR ILLUMINATION ........................................................................... 4
KV6
Feed from the positive battery terminal (C0192) is supplied to fusible link 3 and the main relay (C0632) on an R wire. Both are located in the engine compartment fuse box. Operation of the main relay (C0578) is controlled by the ECM (C0371) on a WK wire. The energised main relay provides a feed to fuse 4, which is also located in the engine compartment fuse box.
Fusible link 3 (C0571) is connected to the ignition switch (C0028) by an N wire. When the ignition switch is turned to the 'ignition' position, current flows across the switch (C0028) to the E-box fan (C0646) on a WR wire.
E-box Fan
Fuse 4 of the engine compartment fuse box (C0575) provides a feed to the E-box temperature sensor (C1258) on an NK wire. The temperature sensor is a thermostatic switch. When the temperature within the E-box reaches 35 °C (95 °F) the switch contact close. Current flows across the switch contacts (C1258) to the E-box fan (C0646) on an NK wire. The E-box fan (C0646) is earthed on a B wire.
When the temperature within the E-box drops to 27 °C (80 °F), the switch contacts within the sensor open, cutting the feed to the E-box fan.
HEATED REAR WINDOW (HRW)
DESCRIPTION General
The HRW comprises eleven metallic strips bonded to the inside surface of the tail door glass to form an element. The metallic strips terminate in two larger strips at the bottom of the glass. Two connectors bonded to the terminations provide attachment of the supply and earth connections.
The HRW is controlled by the Central Control Unit (CCU) via a non latching switch mounted on the centre console. The switch has an illumination LED to show when the HRW is operational. The switch is also illuminated by a separate bulb when the side or headlamps are switched on. For more information on switch illumination, refer to the Interior Illumination section of this manual. + INTERIOR ILLUMINATION.
The CCU will only operate the HRW when all of the following conditions are met: The HRW switch is pressed. The engine is running. The tail door window is closed. The roof is fitted (3 door models only). NOTE: The HRW will not operate if the tail door window has not been calibrated. For more information on tail door window calibration, refer to the Windows section of this manual.

The CCU will switch the HRW off automatically after approximately 15 minutes.
