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.
Air Distribution
Air distribution is as follows:
¥ Defrost duct integral with the fascia.
¥ Face vents, plenum, manifold, centre face
duct, side face duct, side window demist duct
are all sub-assembled into the fascia.
¥ Driver and front seat passenger foot ducts are
installed in the fascia after it has been fitted
to the vehicle.
¥ Rear foot ducts are fitted to the underframe.
¥ Rear face duct fitted to transmission tunnel.
¥ Rear face vent fitted to console.
¥ Extractor boxes fitted in rear quarter panels.
All flaps are electric servo controlled and
comprise:
¥ Fresh/recirculation - heater/evaporator unit.
¥ Cold air bypass - heater/evaporator unit.
¥ Foot flap - mounted on plenum.
¥ Defrost flap - mounted on plenum.
¥ Face flap - mounted on plenum.
Sensors, for operation of the system, are:
¥ Ambient temperature sensor - located behind
the lower front grille.
¥ Solar sensor - fitted to the top centre of the
fascia at the defrost grille
¥ In-car sensor - aspirated from the plenum
venturi sensor mounted inboard of the
steering column.¥ Two heater air outlet sensors
¥ One evaporator air outlet sensor
Servicing
Routine servicing consists of particle filter
replacement.
Replaceable items on the climate control system
are:
¥ Servo complete with linkages
¥ Sensors
¥ Evaporator and seals
¥ Heater core and seals
¥ Blower motor
¥ Impeller/blower motor wheel
¥ Hoses
¥ Registers/vents
¥ Ducts, except the defrost
¥ Defrost and side window demist grilles
¥ Control unit
¥ Compressor
¥ Water pump
¥ Water valve
¥ Receiver/drier
¥ Condenser
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.

also controls the passive anti-theft system (PATS).
General Electronic Control Module (GECM)
The GECM is connected to the SCP
communication network. This module is located
behind the LH ÔAÕ post trim panel below the
fascia. The GECM controls many of the bodysystems, being directly linked to the interior
lighting, wiper and security systems. It is a support
module for other systems including exterior
lighting, locking, remote entry, mirrors
(passenger), seat/mirror/steering column memory
recall and windows.
Rear Electronic Control Module (RECM)

Various languages can be selected for message
display.
For the message center to operate the ignition
must be switched ON (position ÔIIÕ).
The message center displays:
The total distance covered by the vehicle.
Trip computer information.
Warning messages if system faults are detected.
Status messages to indicate changes in state of
certain vehicle functions.
Audio system information when steering wheel
switches are used (when fitted).
Messages
Most messages, when displayed, have an
associated warning light, red or amber, at the side
of the display which will come on to indicate the
message priority.
If more than one message is active, each is
displayed in turn for two seconds in order of
priority.
Messages take priority over the odometer reading

GARAGE DOOR OPENER SWITCHESGarage Door Opener (GDO)
(NAS markets only)
The garage door opening electronic module is
fitted in the driverÕs sunvisor. This module can be
programmed to transmit the radio frequencies of
up to three of the ownerÕs current hand-held
transmitters, for the operation of garage doors,
gates, lighting or security systems, and other radio
frequency operated services.
WARNING:
1. This GDO must not be used with
installations that do not have a sensor
that will automatically ÔstopÕ and
ÔreverseÕ a closing garage door if an
object is detected in its path.
2. When programming a channel, the
system that you are programming will
be activated if it is within signal range,
therefore, make sure that people or
objects are clear of the garage doors or
gates being opened or closed.
The procedure for programming the GDO is given
in the OwnerÕs Handbook.
To operate: Simply press the appropriate button
on the sunvisor. The red light on the sunvisor
comes on when the signal is being transmitted.

System Description
The security system is controlled by a driver door
control module (DDCM). When activated
unauthorized entry in to the vehicle is detected by
the courtesy lamp switches. When the alarm is
triggered, the system flashes the turn signal lamps
and sounds the alarm system horns.
The passive anti-theft system (PATS) is a feature to
prevent the vehicle being driven away by an
unauthorized person. The PATS system consists of
electronically coded keys, a transceiver and is
controlled by the Instrument Pack. When the
ignition is switched to position ÔIIÕ, the transceiver
energises the ignition key to read its electroniccode that is transmitted back. If the read code
equals a stored code in the control module, the
steering column is unlocked and the powertrain
control module (PCM) will let the engine start.
Otherwise, starting of the engine is disabled
(through the starter disable relay and the PCM).
The security indicator LED provides the driver
with the status of the PATS or security system. If
the security system is armed the light will flash
when the ignition is switched OFF. The PATS light
will illuminate when the key is inserted into the
ignition lock and turned to position ÔIIÕ. It will stay
illuminated until the system has carried out its test
on the key. If the system detects a fault, it will
flash the LED for 1 minute, and then flash out the
corresponding 2 digit fault code.

Vehicle Locking and Unlocking
Door locks and handles
Only the driverÕs door has a key lock.
All doors and the luggage compartment can be
locked and unlocked using a key-ring transmitter.
Keys
Two black-headed keys (and one green-headed
key in the North American market) are supplied
with the vehicle. The key number is recorded on a
plastic tag which is attached to each key.
Each black-headed key will operate the ignition
switch and lock the doors, luggage compartment
and the glove box. The green-headed key is a valetkey which will not unlock a locked glove box or
locked trunk lid. The interior and exterior trunk
switches will not unlock the trunk lid when the
valet switch has been set.
An electronic device is fitted in the head of each
key which is programmed to the vehicle
electronics. When the key is placed in the ignition
switch the vehicle electronics recognize the
correct key and allow engine start. The engine
cannot be started with a key not programmed to
the vehicle electronic systems.
Up to eight keys can be used provided the Dealer
programs them all to the vehicle.
Key-ring transmitters
The security system is controlled remotely by a
radio frequency, battery-operated transmitter.
The transmitter is activated by pointing it towards
the vehicle and pressing one of the operating
buttons.
Key-ring transmitters will not operate if a key is in
the ignition switch.
Two transmitters are supplied with the vehicle, but
up to four can be used provided they are all
programmed to the vehicle by the Dealer.
