CONTROL MODULE FAULT & CONDITION SELF-ANALYSIS
0 14.6 14.6.1 System Health
The climate control system has a 'self-test' facility, accessible from the control panel. The self test sequence has two
basic modes:
0 System error information is stored in the A/CCM up to a maximum of five faults. Should a fault occur there will
be an audible 'beep' and the message 'Er' will be displayed on the control panel LCD for approximately five (5)
seconds after ignition on. Please note that this will happen only once in any ignition switch cycle. The error
source may be accessed by the procedure described in 'Self Test System Diagnosis', this section.
0 Panel communication check may be initiated by following the instruction in 'Self Test System Diagnosis', this
section.
Nsfe: Displayed error codes are NOT directly related to Jaguar Diagnostic Equipment (JDE) but more detailed fault
related information may be accessed using Portable Diagnostic Unit (PDU).
14.6.2 System Protection
Power to the compressor clutch may be cut should either the engine management or air conditioning control systems
detect certain conditions; these conditions may be caused by Fault or Demand and can be classified thus:
0 Engine coolant overheat,
0 Refrigerant excessive pressure.
0 Refrigerant, insufficient pressure or low charge weight.
0 Speed differential between compressor and crankshaft caused by belt slippage or compressor seizure (indi-
cated by A/C state lamp flashing once per second) - 12 cylinder engine only. This feature, 'lock sensing' is fully
explained
in the EDM.
Demand
0 Engine maximum power requirement
0 Electrical system drain at engine idle.

15.1.6 Fire Hazard Infonnath
Thermal decomposition or combustion may produce dense smoke and other dangerous fumes which in fire situations
form
a highly toxic explosive.
In the event of fire the surrounding area must be evacuated and
all personnel kept well upwind of the area.
Full fire fighting protective gear and
a self contained breathing apparatus operating in the positive pressure mode must
be worn for combating fire. Material near fires must be cooled with water spray to prevent ignition.
Fires should be allowed to burn themselves
out if not threatening to life or property. If fire is threatening to life or prop- erty use copious quantities of water to extinguish.
15.1.7 Ventilath
Local exhaust ventilation designed by a professional engineer should be provided if vapours, fumes, or dusts are gen- erated whilst working with airbag module.
The latest issue of the manual for recommended practices on 'Industrial Ventilation' is available from the
ACGIH Com- mittee on Industrial Ventilation, PO Box 16153, Lansing, MI 48910, USA.
The need for local exhaust ventilation should be evaluated by a professional industrial hygienist.
15.1.8 Respiratory Precauth
To prevent the inhalation of dangerous fumes and dusts, an approved mask should be worn.
15.1.9 Eye Protection
Chemical protective goggles are recommended where there is a possibility of eye contact with the propellant.
Safety glasses with side shields are recommended for
all other operations.
15.1. I0 Protective Clothing
Approved protective gloves, overalls and shoes / boots should be worn.
15.1.1 1 Handling and Storage Precautions
Do not store airbag module near live electrical equipment or circuitry. Store in a dry environment at ambient tempera-
tures.
Good housekeeping and engineering practices should be employed to prevent the generation and accumulation of
dusts. Store in compliance with
all local state and federal regulations.
15.1.12 Driver And Passenger Airbag Modules Assembly / Removal / Service Instructions
Before starting work, ensure ignition switch is in 'IocK position, key is removed and negative terminal cable
is disconnected from the battery.
As the airbag is equipped with a back up power source and due to the risk of airbag being inadvertently
deployed, wait one minute or longer before starting work.
0 Disconnecting the battery cancels the memory for clock, radio, seats, mirrors, steering column and any other
components using battery power. Reset memory after work is completed.
0 Never use airbags from other vehicles, always use new parts.
0 After work is completed, reconnect battery and perform warning light check see diagnostic manual.
0 Never use electrical probes to check voltage or electrical resistance.
0 Disconnect the airbag before carrying out any work on, or in the vicinity of module, or when using electric weld- ing equipment.
0 Always ensure that battery negative has been disconnected for one minute or longer before commencing any
removal procedure.

A5.3.2 Security system
Base system
Provides standard vehicle arming, ie door ajar, actuator lockstatus, trunk lid or hood ajar and passenger door unlock- ing, does not include inclination or
Intrusion sensing
Detection of intrusion into the passenger compartment by removal or breakage of any glazed area, entry via any pro- tected enclosure and unauthorized door opening detection.
Inclination (tilt) sensing
Detection of unauthorized jacking /towing.
Passive arming
Arming of the security system, excluding intrusion sensors, without audible confirmation.
Audible tones
Audible indication of driver error when attempting to arm the system, or on initiation of deadlocking.
Engine immobilization
Automatic immobilization of the engine crank facility whenever the ignition key is turned to position 0.
A5.3.3 Convenience
All close
Automatic closure of open windows and sliding roof by prolonged action of key, or remote fob transmitter after door
locking.
Headlamp convenience
Automatic illumination of headlamps for driver convenience on operation of key fob button after locking sequence
completed.
Remote trunk lid release
Automatic release of the trunk lid lock on operation of the smaller key fob button after door unlocking.
Trunk valet isolate
Independent locking of the trunk lid to eliminate unauthorized entry to the luggage compartment.
Driver seat memory select
Automatic recall of a memorized driving position on operation of the smaller key fob button.
Intrusion sensing override
Allows intrusion sensing to be disabled until the next disarm action.
A5.3.4 Alarms
There are eight possible alarm activation modes; driver's door, hood, ignition key in (ignition auxiliary position, ignition ON), inclination, inner door handle action (causing actuator status switches to operate), intrusion, passenger door and
trunk.
Any of the above conditions occurring after the vehicle is fully armed will cause full alarm state.
Any of the above conditions, except door opening, occurring
after the vehicle is fully armed and active disarming is
selected will cause full alarm state. Door opening after active disarming selection will give a 30 second audible tick
period before full alarm is entered.
Any of the above conditions occurring
after the vehicle has been passively armed will give a 30 second audible tick
period before full alarm is entered.
Activation of full alarm state causes sidelights, direction indicators, interior lights or headlamps to flash (dependant
upon market variations), the security sounder to operate and the vehicle horns to operate
(if programmed to do so).
An error tone is generated if active arming is selected with either hood or trunk open, or the transmitter is pressed with
ignition key in auxiliary position.
