Heated rear window (hrw) (Electrical)

HEATED REAR WINDOW (HRW)

The HRW is controlled from a non-latching push button switch located on the centre of the fascia.

The CCU controls all functions of the HRW. When the HRW switch is pressed and released a signal is sent to the CCU.

With the ignition on and oil pressure sense present, tail window not lower than the ’clear of seal’ position and, on 3 door models the roof is on, the CCU will grant the HRW on. The CCU will energise the HRW relay for approximately 8 minutes after which the CCU will de-energise the HRW relay. A warning lamp on the HRW switch shows when the HRW is operating.

If the switch is pressed before the timed 8 minute period, the CCU will switch off the HRW. Removal of any of the input signals to the CCU will also stop HRW operation. The HRW switch will require re-selection to operate again.

The CCU HRW inputs and outputs are shown in the following table:

NOTE: The tail window flags are derived from the CCU tracking the window movement using the tail window position signal.
