Down
When down operation of the tail door window is requested, the CCU (C0429) provides a feed 
to the window lift relay module (C0043) on an RG wire. The relay module (C0043) is now 
able to provide a battery feed from fuse 31 of the passenger compartment fuse box (C2625) 
to the window motor (C0612) on a UG wire. Current flows across the motor windings 
(C0612) and back to the relay module (C0043) on a UB wire. The relay module (C0043) is 
earthed on a B wire.
Tail Door Window Motor
The CCU needs to know the position of the tail door window at all times (see Description). 
To do this, the CCU (C0429) provides a feed to a hall effect sensor located within the tail 
door window motor (C0612) on an SP wire. The sensor (C0612) is provided an earth by the 
CCU (C0430) on a KB wire. The hall effect sensor (C0612) provides a signal feed to the 
CCU (C0429) on an SR wire, informing it of the position of the tail door window.
Tail Door Open Switch
The CCU (C0428) monitors the condition of the tail door exterior handle by providing a feed 
to the tail door open switch (C0615) on an N wire. When the tail door handle is operated, 
current flows across the switch (C0615) to earth on a B wire. When the CCU registers this 
earth, it delays opening the tail door and lowers the tail door window approximately 17 mm. 
The CCU (C0428) also monitors the condition of the tail door barrel switch (C0615) on a US 
wire. When the key is turned inside the barrel, current flows across the switch (C0615) to 
earth on a B wire. If the CCU registers a continuous earth path for approximately 2 seconds, 
it will lower the tail door glass.

SUNROOF
DESCRIPTION
General
An electrically operated sunroof is fitted to 5 door vehicles only. The sunroof will only operate 
when the ignition switch is in the ignition position, and is controlled via a non-latching rocker 
switch mounted on the centre console. 
When the upper half of the switch is pressed and held, the sunroof will move to its tilt 
position. When the lower half of the switch is pressed and held, the sunroof will return to its 
closed position. If the lower half of the switch is pressed and held while the sunroof is in its 
fully closed position, the sunroof will slide to its fully open position. The sunroof is closed by 
pressing the upper half of the switch.
OPERATION
General
Feed from the positive battery terminal (C0192) is supplied to fusible link 3 and fusible link 
4 of the engine compartment fuse box (C0632) on an R wire. Fusible link 4 (C0574) provides 
a constant battery feed to the timer relay (C0587) on an NW wire. The auxiliary relay is 
located in the passenger compartment fuse box.
NOTE: The timer relay also controls operation of the heated seats.
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 
fuse 18 of the passenger compartment fuse box (C0588) on an NW wire. Fuse 18 provides 
an ignition feed to the Central Control Unit (CCU) (C0593). The CCU is mounted directly 
onto the rear of the passenger compartment fuse box.
When the CCU receives an ignition feed from fuse 18, it energises the timer relay by 
providing an earth path for the relay coil. The energised auxiliary relay provides a feed to 
fuse 21, which is also located in the passenger compartment fuse box. Fuse 21 (C0585) 
provides a feed to the sunroof switch (C0363) on an SR wire.
Open
When the bottom half of the sunroof switch is depressed (with the sunroof in the fully closed 
position), a feed is provided to the sunroof motor (C0614) from the switch (C0363) on a G 
wire. Current flows across the motor (C0614) and back to the switch (C0363) on an S wire. 
The switch (C0363) is earthed on a B wire. The motor will now power the sunroof back to 
the fully open position.

DOOR MIRRORS
DESCRIPTION
General
The electrically operated door mirrors are controlled via the multi-directional switch mounted 
on the fascia adjacent the instrument pack. Rotating the switch to the left, allows movement 
of the LH door mirror. A movement in the switch position will now be replicated by the LH 
door mirror. Rotating the switch to the right allows movement of the RH door mirror in the 
same way. The central switch position inhibits operation of both door mirrors.
Both mirrors also feature a heating element. The heating elements operate automatically 
when the ignition switch is in the ignition position, and are not controllable by the driver.

+  DOOR MIRRORS. 
OPERATION
General
Feed from the positive battery terminal (C0192) is supplied to fusible link 3 and fusible link 
4 of the passenger compartment fuse box (C0632) on an R wire. Fusible link 4 (C0574) 
provides a feed to the time–out relay and fuse 16 of the passenger compartment fuse box 
(C0587) on an NW wire. Operation of the time–out relay is controlled by the Central Control 
Unit (CCU) (C0592).
Folding Mirror ECU
Fuse 16 of the passenger compartment fuse box (C0580) provides a constant battery feed 
to the folding mirror ECU (C0907) on a P then NS wire. The folding mirror ECU is located at 
the base of the passenger side A post, and is earthed on a B wire.
The folding mirror ECU (C0907) monitors the condition of the door mirror switch (C0066) on 
a UB wire. When the switch is pressed, a momentary earth path is created on a B wire via 
the door mirror switch (C0066) and the passenger compartment fuse box (C0589 & C0587) 
on a B wire. When the folding mirror ECU senses this earth, it powers both folding mirror 
motors.
Door Mirrors
When the folding mirror ECU senses the door mirror switch has been pressed, it provides a 
feed to the LH folding mirror motor (C0444) on a Y then R wire, and the RH folding mirror 
motor (C0444) on a Y then B wire. Current flows across the motors (C0444) and back to the 
folding mirror ECU on a B then O wire (LH) and an R then O wire (RH).

HEATED SEATS
DESCRIPTION
General
The heated front seats are switched on and off by pressing either of the switches mounted 
on the centre console. The heated front seats are operated independently of each other. The 
switches also incorporate an illumination LED to show when the seat heaters are switched 
on.
OPERATION
General
Feed from the positive battery terminal (C0192) is supplied to fusible link 3 and fusible link 
4 of the engine compartment fuse box (C0632) on an R wire. Fusible link 4 (C0574) is 
connected to the timer relay (C0587) by an NW wire. The earth path for the relay coil is 
controlled by the Central Control Unit (CCU) (C0592), which is mounted directly onto the 
rear of the passenger 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 
fuse 18 of the passenger compartment fuse box (C0588) on an OG wire. Fuse 18 provides 
an ignition feed to the CCU.
When the CCU receives an ignition feed, it energises the timer relay by providing an earth 
path for the relay coil. The energised timer relay provides a feed to fuse 11, which is also 
located in the passenger compartment fuse box.
Fuse 11 (C0585) provides a feed to the LH heated seat switch (C0249) and the RH heated 
seat switch (C0250) on N wires.
LH Seat
When the LH heated seat switch is pressed, current flows across the switch contacts 
(C0249) to the LH heated seat relay (C1221) on a US then R wire. Operation of the heated 
seat relay (C1221) is controlled by the temperature sensor on a G wire. The temperature 
sensor is a normally closed switch. Current flows across the switch to earth on a G then N 
then B wire.
When the temperature of the seat is within acceptable levels, the heated seat relay (C1221) 
provides a feed to the seat heater elements on an RW wire. The elements are wired in series 
and earthed on an N then B wire.
If the temperature sensor detects the temperature of the seat is too high, it cuts the earth 
path for the heated seat relay. This de-energises the relay until seat heat temperature 
decreases to acceptable levels.

RH Seat
When the RH heated seat switch is pressed, current flows across the switch contacts 
(C0250) to the RH heated seat relay (C1221) on a UK then R wire. Operation of the heated 
seat relay (C1221) is controlled by the temperature sensor on a G wire. The temperature 
sensor is a normally closed switch. Current flows across the switch to earth on a G then N 
then B wire.
When the temperature of the seat is within acceptable levels, the heated seat relay (C1221) 
provides a feed to the seat heater elements on an RW wire. The elements are wired in series 
and earthed on an N then B wire.
If the temperature sensor detects the temperature of the seat is too high, it cuts the earth 
path for the heated seat relay. This de-energises the relay until seat heat temperature 
decreases to acceptable levels.
