OPERATION
General
Feed from the positive battery terminal (C0192) is supplied to the horn relay, fuse 6, fuse 7, 
fuse 10, and fusible link 4 (C0632) on an R wire. All are located in the engine compartment 
fuse box. Fuse 10 (C0575) provides a constant battery feed to the inertia switch (C0123) on 
a G wire. Fuse 7 (C0576) provides a constant battery feed to the hazard warning relay 
located in the passenger compartment fuse box (C0580) on an NO wire. 
Fusible...

Roof On Switch (3 Door Vehicles Only)
The roof on switch (C0497) is located on the RH D post, and is provided a constant battery 
feed by fuse 14 of the passenger compartment fuse box (C0580) on a P wire. The roof on 
switch is closed when the hard back is fitted, or the soft back is in the fitted position. In this 
instance, current flows across the switch (C0497) to the CCU (C0428) on a PY wire.
If the hard back is removed (or the soft back is folded down)...

Volumetric Sensor
The CCU (C0429) provides a feed to the volumetric sensor (C0358 on 3 door vehicles, 
C1896 on 5 door vehicles) on a WB wire. When the alarm is armed, the volumetric sensor 
(C0358 on 3 door vehicles, C1896 on 5 door vehicles) returns a signal feed back to the CCU 
(C0428) on an NB wire. If the sensor detects movement within the vehicle, it withdraws the 
signal feed to the CCU. Sensing this, the CCU will sound the alarm.
The CCU (C0429) also...

Door Lock Motors
When the CCU receives a request to lock or unlock the doors, it powers the door lock motors 
as follows:
Driver Door
To lock the driver door, the CCU (C0430) provides a feed to the driver door lock motor 
(C0441) on a K wire. The motor (C0441) is provided an earth path via the CCU (C0430) on 
an O wire. This enables the motor to drive the latch to the lock position.
To unlock the driver door, the CCU (C0430) provides a feed to the driver door...

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 (C0928) on a GR wire
zThe RH rear direction indicator lamp (C0837) 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...

Immobilisation ECU Inputs/Outputs
The immobilisation ECU receives inputs and outputs from a number of different components 
to ensure the right criteria are met before it will allow the engine to be started.
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...

DESCRIPTION AND OPERATION
FREELANDER 04MY 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...
