14.10 FAULT DIAGNOSIS
14.10.1 Introduction
It is very important to positively identifythe area of concern before starting a rectification procedure. A little time spent
with your customer to identify the conditions under which a problem occurs will be beneficial. Relevant criteria are:
Weather conditions, ambient temperature, intermittent or continuous fault, airflow fault, temperature control fault, dis
- tribution fault and air inlet problem.
14.10.2 Functional Check
This simple 'first line check' will allow you to ascertain whether the system is operating within its design parameters,
without recourse to (JDE). Please carry out the following, in order.
0 Start engine and attain normal running temperature.
0 Presss AUTO to display selected temperature and illuminate AUTO & AJC state lamps.
0 Rotate FAN to increase or decrease lower speed, verify bar graph representation.
0 Operate AJC to toggle on or off. Because the compressor can be inhibited by the engine management system,
ensure that the engine temperature is normal and that the ambient is above 5O C.
0 Operate RECIRC, state lamp should be lit and the flap behind the blower grille open.
0 Operate distribution buttons in turn, verify correct air distribution and relevant state lamp.
0 Operate DEFROST, check max fans and air to front screen.
0 Cycle TEMPERATURE to 'Hi' and 'Lo' to verify demanded variations and display operation. Note that extremes
will provide max heat or cold independent of in-car temperature.
0 Operate EX to toggle between ambient and control temperatures.
0 Operate HFS and HRW to note timer and mirror operation.
0 Initiate System Self Test to check for, and extract, stored faults should any of the above not perform as stated.
14.10.3 System symptoms
There are five basic symptoms associated with air conditioning fault diagnosis. The following conditions are not in order of priority.
No Cooling
0 Is the electrical circuit to the compressor clutch functional?
0 Is the electrical circuit to the blower motor(s) functional?
0 Slack or broken compressor drive belt.
0 Compressor partially or completely seized.
0 Compressor shaft seal leak.
0 Compressor valve or piston damage (may be indicated by small variation between HIGH &LOW side pressures
relative to engine speed).
0 Broken refrigerant pipe (causing total loss of refrigerant).
0 Leak in system (causing total loss of refrigerant) - possible code 23.
0 Blocked filter in the receiver drier.
0 Evaporator sensor disconnected - possible code 13.
0 Pressure switch faulty - possible code 23.

The vehicle closures switching system comprises the security and central locking features applicable to that vehicle
variant, as detailed in the table below. Central locking and security systems are controlled by a common electronic
module designated as the Security and Locking Control Module (SLCM). The term closures refersto items which allow
access to the vehicle interior and therefore must be closed when the vehicle is fully alarmed. these components are

A5.3 GENERAL INFORMATION
The following information detailsthe purpose and function of the system components irrespective of individual variant
features.
A5.3.1 Locking:
Central locking
A traditional central locking application, such that when the driver's / passenger's door is locked / unlocked using the
door key all four doors lock / unlock simultaneously.
1ynfe: Locking operations will only take place when all doors are completely closed.
Remote central locking
Automatic locking / unlocking, activated by the larger of the two key fob buttons.
1ynfe: Locking operations will only take place when all doors are completely closed.
Deadlocking
A means of securing door locks so that they cannot be opened using the interior release mechanism, and arming the
security sensing system, using the door key or remote transmitter
Two-otage unlocking
A key / remote operated unlocking procedure which releases driver's door and fuel filler cap locks only, initially, and
then releases all other doors and the luggage compartment locks.
Drive-away locks
Automatic locking of all doors, and luggage compartment (but not fuel filler cap), when gear selector is moved away
from 'Park' and the ignition switch is in position II, providing all doors are closed.
Central lock / unlock, all close
Automatic locking of all doors and luggage compartment by operation of the fascia mounted central locking switch.
Continued switch operation causes closure of sliding roof and open windows.
Interior trunk lid release
Trunk lid unlocking from fascia mounted switch.
Flush sill buttons / intrusion override
Sill buttons fitted flush to door trim panel to prevent unauthorized override operation, buttons are latched in position
when deadlocking is applied.

A5.7.7 Central Locking
W
With the ignition switch in either position 'I' or 'll', press the central locking switch and check that all the doors and the
luggage compartment lock, if they are unlocked.
Hold down the switch for
3 seconds and check any open windows or the sliding roof close, if open.
Check that
a further press on the central locking switch after 3 seconds will unlock the doors and the luggage compart- ment.
If the switch is pressed when ignition switch is not in position I or II, tilt and intrusion sensing will be disabled until the
next arming action. The active indicator, mounted in the switch housing, will flash to confirm this action.
To disarm
a passively armed vehicle the ignition key or key-ring transmitter can be used as follows:
Ensure
all doors
are fully closed before commencing lock operations.
0 Ignition key - Switch to position '11'.
0 Key-ring transmitter - Refer to A5.3.5 Unlocking.
A5.7.8 Passive Arming
Passive arming is a dealer option on variants 1 and 3 only.
With the ignition switch in the OFF position, check that passive arming of the vehicle takes place
30 seconds after the last closure of the doors, trunk lid, hood or sliding roof.
Ensurethat when passive arming occurs, the direction indicators flash once and the security active indicator in the cen
- tral locking switch lights for 2 seconds then flashes once when vehicle arming is complete.
W There is no audible indication when passive arming occurs.
A5.7.9 Trunk Release
Check that the the trunk lid can be released in the following ways:
0 From the vehicle interior by pressing the trunk release switch mounted on the facia.
0 By using the ignition key in the trunk lid if the vehicle is disarmed. If not disarmed the the alarm system will be
activated and can be switched off by ignition key or key-ring transmitter.
0 Remotely (as part of the unlocking procedure) by the key-ring transmitter.
A5.7.10 Trunk Valet Isolate
Check that valet switch operation prevents unauthorized entry into the luggagecompartment by inhibiting the luggage
compartment remote release switch and the green headed valet key can be used to park and lock the vehicle but does
not unlock the luggage compartment.
A5.7.11 Flush Sill Buttons
Variants 1 and 3 (except Japanese market) are fitted with flush sill buttons mounted in the door trim panel. Check but- ton operation as follows:
To lock the door from the interior press the sill button down, flush with the door trim panel. To unlock the door pull the
door lever out.
