1. Connect an R-134a Recovery / Recycling / Recharging
unit to the vehicle A/C system.
2. Follow the Recovery / Recycling / Recharging unit manufacturer’s instructions to evacuate the A/C system.
Evacuation
The removal of unwanted air and moisture, is critical to the
correct operation of the A/C system. Moisture in the system
can be highly destructive and may cause internal blockages
due to freezing; water suspended in the lubricating oil will
damage the compressor. Once the A/C system has been
dismantled, or the refrigerant charge recovered, all traces of
moisture must be removed before charging.
Read manufacture’s instruct ions and warnings before
completing any Recovery / Recycling / Recharging
operation.
1. Connect an R-134a Recovery / Recycling / Recharging unit to the vehicle A/C system.
2. Follow the Recovery / Recycling / Recharging unit manufacturer’s instructions to evacuate the A/C system.
Charging
Read manufacture’s instruct ions and warnings before
completing any Recovery / Recycling / Recharging
operation.
1. Connect an R-134a Recovery / Recycling / Recharging unit to the vehicle A/C system.
2. Follow the Recovery / Recycling / Recharging unit manufacturer’s instructions to charge the A/C system.
Compressor oil may be drawn ou
t during this process, take
note of the quantity recovered so that it may be replaced.
It is recommended that initiall y only the high-side valve be
opened at the start of the pr ocedure. After a short time a
small depression should be seen on the low-side, at which
point the low-side valve may be opened and the evacuation
process completed. If a vacuum is not registered on the
low-side, it may indicate that the expansion valve is
permanently closed or that th e system is blocked. This
simple check may save time and effort when the system is
recharged.
Caution
Do not exceed the specificat ion when charging the A/C
system with refrigerant. Doing so will decrease the
efficiency of the A/C unit or damage the refrigeration cycle parts.
Caution
Always start the charging of refrigerant from the high-
pressure side. If charging st arts from the low-pressure
side, vanes of the A/C compressor will not be released and abnormal noise may result.

Leaks
Faults associated with low refrigerant charge weight and low pressure may be caused by leakage. Leaks traced to
mechanical connections may be caused by torque relaxation or joint face contamination. Evidence of oil around such
areas is an indicator of leakage.
Leak Detection
Fluorescent Tracer Dye - A fluorescent tracer dye is incorporated into th e refrigeration system and can be checked for
non-apparent leaks by scanning with a high intensity ultraviolet lamp. The location of leaks can be pinpointed by the bright
yellow glow of the tracer dye.
Automatic Refrigerant Leak Detector - (various manufacturers) Hand-held, portable, battery operated leak detector.
Place in and around A/C system to detect refrigerant leaks.
System Pressure Fault Classification
This table should be used in conjunction with the graphical representations of 'High side' pressure / ambient temperature
and 'Low side' pressure / evaporator temperature. Caution
Observe ALL safety precautions associ ated with ultraviolet equipment.
If erratic or unusual gauge movements occur, check the equipment against known Recovery / Recycling / Recharging unit
gauges.

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.

Relays
Another significant component in the circuits is a relay, this
is in simple terms a switch that operates on the principal of
electromagnetism. Below is the circuit symbol for a typical
relay. The relay shown below is a normally open relay in its
inoperative state i.e The arm is in the open position.
Relays can have either 4 or 5 terminals on the base. The
circuit of the relay is shown on the base or the side of the
housing. There are 2 types of numbering convention for the
relay terminals, both of which are shown below.
Below is a circuit diagram to show the function and
operation of a relay in a simple circuit.
The current from a battery for example flows through the
wires to the high power normally open switch (The arm
between pins 30 & 87A) and the low power coil (The box
between pins 85 & 86). As you can see in the example above
the lamp is in not illuminated, because the switch is open.
For the relay to operate there needs to be current flow
through the low power coil i.e Current in to the coil then
through to an earth. The current passes through the relay coil
and creates a magnetic field, this magnetic field is strong
enough to ‘grab’ the high power normally open switch.
The magnetic field pulls the switch from it’s normally open
contact to a normally closed contact. The normally closed
contact has a path to an earth, in this case it goes through a
lamp. The high power current then flows through the high power
normally open switch through the lamp and then to an earth.
This can be seen more clearly in the diagram below.Lamp
Illuminates
Busbars
A busbar is where a electrical
supply is fed into a conductive
bar, wire or pcb track and various modules or components
‘tap’ into this busbar to draw their required power. The
Central Electronic Module has 4 of these busbars internally,
each of which is supplied from an external power supply,
that supply can be a battery feed, ignition feed or a switched
supply.
The symbol shown below is the symbol used on the circuits
for a busbar, the number inside the box refers to the busbar
number in the Central Electronic Module.
Fuses
A fuse is a device used to protect a module or component
from excessive electrical current which can cause damage or
destroy that module or component. In practice the fuse is
placed in between the power source and the module or
component that is being protected.
The size or ‘Rating’ of the fuse in amps is calculated
according to the power requirements of the module or
component it is protecting with other factors being taken
into consideration. If the rating has been calculated correctly
then the fuse will ‘blow’ when excessive current passes
through it before any harm or permanent damage occurs to
the module or component it is protecting.
