Tail Door
Operation of the tail door latch mechanism is only possible when the vehicle is stationary or 
travelling at speeds lower than 3 mph (5 km/h). To allow the tail door latch to operate, the 
CCU (C0430) provides a single voltage pulse to the tail door motor (C0617) on a PU wire. 
The motor (C0617) is earthed on a B wire. 
The CCU receives a road speed signal from the ABS ECU. If road speed rises above 3 mph 
(5 km/h), the CCU will not provide a voltage...

LH Rear Door
To superlock the LH rear door, the CCU (C0430) provides a feed to the LH rear door 
superlock motor (C0442) on an NK wire. The superlock motor (C0442) is provided an earth 
path via the CCU (C0430) on an O wire. This powers the superlock motor to the lock 
position, inhibiting the interior door handle.
To unlock the LH rear door from the superlock condition, the CCU (C0430) provides a feed 
to the LH rear door lock motor and the superlock motor...

Direction Indicator/Hazard Warning Lamps
If the anti-theft alarm is triggered, the CCU (C0593) provides an earth path for the hazard 
warning relay coil. The energised hazard warning relay provides a feed to the following:
zThe LH rear direction indicator lamp (C0121) on a GR wire
zThe RH rear direction indicator lamp (C0125) on a GW wire
zThe LH front direction indicator lamp (C0009) on a GR wire
zThe RH front direction indicator lamp (C0011) on a GW wire...

ENGINE IMMOBILISATION
DESCRIPTION
General
The function of the engine immobilisation system is to prevent unauthorised starting of the 
vehicle. The system is controlled by the immobilisation ECU, which is located behind the 
centre of the fascia. Re-mobilisation is achieved via a transponder in the vehicle key, which 
is read by a transponder coil when the ignition switch is turned to the auxiliary position. The 
transponder coil is mounted around the...

Transponder Coil
The transponder coil (C0049) mounted around the ignition barrel, and is connected to the 
engine immobilisation ECU (C0059) by KB and KG wires. Both connections between the 
immobilisation ECU and the transponder coil switch between both inputs and outputs. The 
transponder coil reads the vehicle identification information contained within the key 
transponder and relays it to the immobilisation ECU. The immobilisation ECU (C0059) then...

DESCRIPTION AND OPERATION
FREELANDER 03MY 4.11
Starter Relay
If the vehicle has been successfully re-mobilised, the immobilisation ECU (C0059) provides 
a feed to the starter relay coil (C0576) on an RW wire. The relay coil (C0576) is earthed on 
a B wire. The energised relay allows a feed from fusible link 7 to flow across the relay switch 
contacts (C0572) to the starter motor (C0179) on an NR wire (NR then B on Td4 vehicles). 
For more details of starter motor operation, refer to the  Charging and...

WINDOWS
DESCRIPTION
Door Windows
The front and rear electrically operated windows are opened and closed by using the 
appropriate non-latching switch mounted on the centre console. Rear window switches (if 
fitted) are also located on the rear door trim casings. Rear window operation can be 
controlled by the driver by pressing the rear window inhibit switch, which is also mounted on 
the centre console.
The window lift system is controlled by the window lift...

DESCRIPTION AND OPERATION
FREELANDER 03MY 4.13
If the rear wiper is operational, the tail door window will not lower until the wiper is on a 
downward stroke. When the window is in the lowered position, wiper operation will be 
suspended. The tail door window will be disabled if any of the following occur:
zThe soft back is lowered.
zThe soft back is removed.
zThe hard back is removed.
Tail Door Window Calibration
When the CCU is changed from transit mode to a valid market mode, and after the vehicle...

Window Lift Relay
The earth path for the window lift relay coil is controlled by the CCU (C0593). When the CCU 
(C0593) receives an ignition on feed from fuse 8 of the passenger compartment fuse box, 
it will energise the window lift relay. The energised window lift relay provides a feed to fuse 
33 and fuse 34, which are also located in the passenger compartment fuse box.

Fuse 33 of the passenger compartment fuse box (C0586)...

DESCRIPTION AND OPERATION
FREELANDER 03MY 4.15
The driver door window switch (C0242) is earthed on a B wire. The window will now move 
to the fully lowered position.
When the driver door window switch is pressed to raise the window, current flows across the 
switch (C0242) to the window lift ECU (C0341) on an OY wire. The window lift ECU (C0341) 
now provides a feed to the driver door window lift motor (C0326) on a U then OU wire. 
Current flows across the motor (C0326) back to the window lift ECU...
