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 (C0583) 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.

The CCU (C0429) also provides a gain setting signal to the volumetric sensor (C0358 on 3 
door vehicles, C1896 on 5 door vehicles) on an SW wire. This enables the volumetric sensor 
to determine if it is looking at the interior of a 3 door vehicle or a 5 door vehicle and adjust 
its sensitivity accordingly.
The volumetric sensor (C0358 on 3 door vehicles, C1896 on 5 door vehicles) is earthed on 
a B wire.

Passenger Door
To lock the passenger door, the CCU (C0430) provides a feed to the passenger 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 passenger door, the CCU (C0430) provides a feed to the passenger door lock 
motor (C0441) on an O wire. The motor (C0441) is provided an earth path via the CCU 
(C0430) on a K...

Superlocking
Superlocking inhibits the use of the interior door handles in addition to driving the door lock 
motors to the lock position. When the CCU receives a request to superlock the doors, it 
supplies the following outputs in addition to those detailed above in the  Door Lock Motors  
description.
NOTE: The vehicle will not start if the vehicle is superlocked. For more information, refer to 
the Engine Immobilisation section of this manual.

RH Rear Door
To superlock the RH rear door, the CCU (C0430) provides a feed to the RH 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 RH rear door from the superlock condition, the CCU (C0430) provides a feed 
to the RH rear door lock motor and the superlock motor...

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 ignition...

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...
