Drivers Door
The BCU controls operation of the drivers door lock via the drivers door module. The drivers 
door module (C2017) is provided a constant battery feed from fuse 11 of the passenger 
compartment fuse box (C0585) on an RP wire. The module (C2017) is earthed on an N wire.
The BCU (C0660) communicates with the drivers door module (C2058) via the P-bus on a 
UR wire. If the drivers door module (C2058) receives an unlock signal from the BCU, it 
provides a...

Rear Passenger Doors
When the BCU (C0662) receives an unlock signal from the RF receiver, it provides a feed 
to the RH and LH rear (C0442) door lock motors on a pair of U wires. Current flows across 
the motors (C0442) to earth path via the BCU (C0662) on a pair of B wires.
When the BCU (C0662) receives a lock signal from the RF receiver, it provides a feed to the

ENGINE IMMOBILISATION
DESCRIPTION
General
The function of the engine immobilisation system is to prevent unauthorised starting of the 
vehicle. The system is controlled by an immobilisation ECU which is located beneath the 
centre console, adjacent to the handbrake. 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...

Transponder Coil
The transponder coil (C0049) is connected to the immobilisation ECU (C0059) by YU and 
YN wires. Both connections between the immobilisation ECU and the transponder coil 
switch between being both inputs and outputs. The transponder coil reads the vehicle 
identification information contained within the key transponder and relays it to the 
immobilisation ECU.

WINDOWS
DESCRIPTION
General
Operation of all four windows is controlled by the Body Control Unit (BCU) via the P-bus. 
The P-bus allows communication between the BCU and the drivers and passenger door 
modules. The door modules are mounted in the relevant front door. The drivers door module 
features four rocker switches, and a non-latching switch to inhibit operation of the rear 
windows. A rocker switch is also located on the front passenger door, and both...

DESCRIPTION AND OPERATION
4.14RANGE ROVER
When the drivers door switch is moved to the Down position, the feed from fuse 11 of the 
front passenger compartment fuse box (C0585) flows through the drivers door module 
(C2017) to earth on an N wire. The drivers door module (C2017) will now provide a feed to 
the window lift motor (C0740) on a BG wire. Current flows across the motor and back to the 
drivers door module (C2017) on a BS wire. The drivers door module provides an earth path 
for the motor on an...
