Major Components
Compressor
• Engine mounted, driven by the accessory drive belt
• Variable displacement type
• High-pressure relief valve, to avoid system over-pressure
• ECU controlled clutch energised via a relay
Receiver drier
• Vertically mounted on the right-hand side of the engine bay
• The high-side charge port is installed to the high side entry pipe to the receiver drier
Condenser
• Multi-pass fin-over-tube type, mounted in front of the engine cooling pack and directly to the radiator
Trinary switch
Located in the compressor discharge pipe
• Provides a signal, via the A/C module, to the PCM, to disengage the compressor clutch should the refrigerant
pressure be less than 2 bar or greater than 30 bar
• Provides a hard-wired signal to the PCM, to switch the cooling fans to HIGH speed at 22 bar rising pressure and
to LOW speed at 17,5 bar falling pressure
• Provides a hard-wired signal to the PCM, to switch the radiator cooling fans to LOW speed at 12 bar rising
pressure and to switch the fans OFF at 8 bar falling
pressure
Expansion Valve
The expansion valve is located on the outside of the A/C unit
and comprises of a diaphragm, connected by a capillary
tube to a temperature sensing bulb, which regulates the
valve according to temperature variations at the evaporator
outlet pipe. This component is not serviceable.

Symptom (7)DescriptionPossible Cause
Air from vents not cold enough. Magnetic clutch operates but A/
C system malfunctions. • Drive belt fault
• Fault in blower unit or condenser
• Fault in Receiver / Drier or expansion valve
(valve closes too much)
• Fault in refrigerant lines
• A/C compressor system fault, insufficient compressor oil
• Over filling of compressor oil, fault in expansion valve or A/C unit air mix link system
Symptom (8)Possible Cause
No cool air. Magnetic clutch does not
operate. • Fault in PCM A/C cut control system
• Fault in A/C Module
• Fault in refrigerant pressure switch
• Fault in PCM (A/C signal)
• Fault in PCM (IG1 signal)
• Fault in A/C compressor
•Fault in A/C relay
• Fault in Evaporator Temperature Sensor
Shake the wiring harness and connectors wh ile performing the inspection to discover whether poor contact points are the
cause of any intermittent malfunctions. If there is a problem, check to make sure connectors, terminals and wiring harnesses
are connected correctly and undamaged.
Symptom (9)Possible Cause
Noise while operating A/C
system. Noise from magnetic clutch, A/C
compressor, hose or refrigerant
line. • Magnetic clutch operation noise
• A/C compressor slippage noise
• Hose or refrigerant line interference noise

Power Supply (14.00)
Alternator and Regulator System (14.02)
Description
The alternator installed to this vehicle is a Denso, SC1, 120
amp rating, with a 14.4 volt regulator.
The Alternator has an 'Altmon' signal that goes to and from
the PCM via a wire in the 3 way connector.
The ‘Altmon’ signal is monitored by the PCM which adjusts
ignition timing and fuelling if necessary to maintain idle
speed when the alternator is charging.
