67 Pipework
The suction hose and liquid line are a one-piece
assembly. A single screw connects them to the air
conditioning unit manifold at the bulkhead. A
further screw fixing and push-in clip secures them
at the side of the engine bay. The liquid line fixed
to the cooling module then joins with a block
fitting and the suction hose connects with a quick
connect fitting and routes across the underneath
of the cooling module to the compressor. The
compressor suction and discharge hoses are also a
one piece assembly.
A pressure transducer is fitted to the discharge
hose as it connects to the rear of the condenser.
The high side charge port is situated on the
manifold connecting to the receiver drier whilst
the low side is adjacent to the compressor behind
the LH front wheel.
The compressor is a 9Occ scroll, which is variable
from 100% to 30%. Compressor is standard
specification to all vehicles although package
makes them unique to V6 and V8.

There are no panel diagnostics but PDU facility is
available with extensive capability, similar to
current XJ and XK Series.
System refrigerant is R134a. Vehicle charge weight
is 800 gms and charging is through the high side
charge port only.
Oil type is WSH-MIC231-B and refill quantity is
180 cc -220 cc.
Special tools are hose clamp pliers and air-
conditioning hoses spring lock de-coupler.
General information
Ensure that the grille at the base of the windshield
is kept clear of leaves, snow or other obstructions.
A solar sensor is mounted on top of the fascia, in
the centre of the defrost grille, and this should not
be covered.
The air conditioning system should be run briefly
at least once each week with a cold setting to
prevent the seals from drying out with subsequent
refrigerant leaks.
When the engine and vehicle interior are cold the
fan speed may be low until the engine has warmed
up, this avoids excessively cold air being blown
into the cabin.

68Heated wiper park or (where optionally fitted)
heated front screen.
With the engine running, due to the high current
draw, press to switch on the heated wiper park to
defrost the wiper park area, or where fitted, press
to switch on the heated front screen for rapid
defrost/demist.
Heated wiper park automatically operates in cold
weather, and may stay on continuously. It is
automatically switched on when ÔDEFROSTÕ is
selected. If manually selected, the heated wiper
park will automatically switch off after 10
minutes.
Heated front screen is automatically switched on
when ÔDEFROSTÕ is selected. It will automatically
switch off after 4 minutes. The heaters will switch
off, or not operate, if low battery voltage is
detected.
Heated Rear Screen
With the engine running due to the high current
draw, press to switch on the heated rear screen
for rapid defrost/demist. The rear screen heater
will be automatically switched off after 10
minutes.
In cold conditions, the heated rear screen
operates automatically. Selecting ÔDEFROSTÕ will
also turn the heated rear screen ON. The heaters
will switch off, or not operate, if low battery
voltage is detected.
Air Distribution
Air distribution is automatically controlled when
ÔAUTOÕ is selected. Manual control can be
achieved using the air distribution buttons.
Heat at Rest Feature (V8 engine vehicles
only)
Interior heating may be continued after the
engine has been switched off by turning the
ignition to position ÔIIÕ. The climate control system
will continue to provide heat to the vehicle
interior until the engine cools down. Excessive use
will cause a low battery voltage, which may
prevent the vehicle from being started.
Voice Activated Control
Some functions of the climate control system can
be operated with the Voice Activation System
(when fitted).
A full operating description is given in the Voice
Activation Handbook included with the vehicle
literature pack.

74The SCP communication network will remain
operational even with severing of one of the bus
wires. Communications will also continue if one
of the bus wires is shorted to ground or battery
positive voltage (B+), or if some , but not all,
termination resistors are lost.
Unlike the SCP communication network, the
ISO 9141 communication network will not
function if the wire is shorted to ground or battery
positive voltage (B+). Also, if one of the modules
on the ISO 9141 network loses power or shorts
internally, communication to that module will fail.
Control Modules
The vehicle control module functions are
described briefly below (for further information
refer to the relevant sections throughout the
Guide).
Anti Lock Brake/Traction Control and
Dynamic Stability Control, Control Modules
The anti-lock brake control module is connected
to the SCP communication network. The module
comes in two forms. The first type is the standard
equipped anti-lock brake system (ABS) with
traction control (TC). It controls the brake
pressure to the four wheels to keep the vehicle
under control while braking.
The second type of ABS is optional and is called
dynamic stability control (DSC). This control
module adds yaw sensors to the package to help
in sensing a loss of vehicle control.
Audio Control Unit
The audio control unit is connected to the SCP
communication network and also to the audio
control protocol (ACP) communication network.
The audio control unit communicates with the
compact disc and the cellular phone transceiver.
Driver Door Control Module (DDCM)
DDCM is connected to the SCP communication
network. The module controls many functions
including power windows, driver mirror, power
locks, and keyless remote entry.Driver Seat Control Module (DSCM)
The DSCM is connected to the SCP
communication network. The DSCM is located
under the driver seat and controls the seat
positions. The module also communicates with the
DDCM to control the driver seat memory
functions.

Front Seat Heater Switches
The driver and front passenger have a heater. The
seat heater switches (when fitted) are located on
the center console directly below the climate
control unit. The heaters are in the seat squab
and the seat cushion. The heater will
automatically switch OFF after it has been on for
10 minutes. The heater will maintain a pre-set
temperature while it is switched on. Storage of
the vehicle in a heated garage, body heat, or
warm ambient temperatures may prevent
operation of the seat heater.
