HEATED FRONT SCREENF6
CIRCUIT OPERATION1
CIRCUIT OPERATION
This operates only with the engine running, which is
determined by the HEVAC panel. In the off state, the
signal is at 12 volts. When the Heated Front
Windscreen is activated, the signal is switched to 0
volts. This provides the ground required for relay 5 to
be pulled in, as there is an ignition feed on the other
side of the coil provided by relay 15. This relay
energises one half of the heated screen elements.
Once relay 5 has been energised, a...

CIRCUIT OPERATION1
CIRCUIT OPERATION
The rear screen heater will reflect the state of the
heated rear screen input from the HEVAC unit at any
time while the BeCM (Z238) is in the active mode.
This signal is normally 12V and 0V when active (Ac-
tive Low).
The HEVAC unit will control all timing functions re-
lated to the rear screen heater.

CIRCUIT OPERATION
Dipped Beam Headlamps
Operation of the headlamp switch will activate the
LH and RH dipped beam headlamps, regardless of
the state of the ignition switch.
Headlamp Delay
The term ªheadlampº used throughout this section is
assumed to be either dipped beam or main beam, as
selected by the main beam changeover switch. This
switch will continue to function for the duration of the
delay period.
The headlamps will operate when the headlamp
switch is set to the...
