Vehicles WITH Adaptive System Installed


CAUTION: When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part
number 3548-1358-00
NOTES:


If a module or component is suspect, and the vehicle remains under the Manufacturers warranty, refer to the Warranty
Policy and Procedure manual (section B1.2), or determine if any prior approval programme is in operation, prior to the
installation of a new module/component.


Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan
tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give extra information read by
the manufacturer-approved diagnostic system).


When performing voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal places and
with a current calibration certificate. When testing resistance, always take the resistance of the DMM leads into account.


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.


If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals.

Flushing
General Procedures

1. WARNINGS:


Use extreme care and observe all safety precautions related to the
use of refrigerants. Due to refrigerant hazards, always wear safety
goggles and non-penetrable gloves when working on or flushing air
conditioning (A/C) systems. Failure to follow this instruction may result
in personal injury.


When flushing the A/C system, refer to the manufacturers
equipment instructions for additional information. Failure to do so may
result in system damage or personal injury.


The A/C refrigerant analyzer must be used before the recovery of
any vehicle's A/C refrigerant. Failure to do so puts shop bulk refrigerant
at risk of contamination. If the vehicle A/C refrigerant is contaminated,
refer the customer to return to the repair facility that performed the last
A/C repair. If the customer wishes to pay the additional cost, use the
A/C recovery equipment that is designated for recovering contaminated
A/C refrigerant. All contaminated A/C refrigerant must be disposed of as
hazardous waste. For additional information, refer to the manufacturers
equipment instructions. Failure to follow this instruction may result in
personal injury.


Prior to using the A/C flushing equipment for the first time, follow
the operating instructions. Failure to follow this instruction may result in
personal injury.


CAUTION: Prior to flushing, remove and discard the desiccant sack.
Depending on the equipment used, other A/C components may have to
be removed prior to flushing. For additional information, refer to the
manufacturers equipment instructions before flushing the A/C system.
Recover the refrigerant.
For additional information, refer to Air conditioning (A/C) System Recovery, Evacuation and Charging in this section.
2. Remove the desiccant sack.
For additional information, refer to Section 412-03 Air Conditioning.
3. Flush the system. For additional information, refer to the manufacturers
equipment instructions.

4. Install new refrigerant lines if blocked with debris.

5. Install a new desiccant sack.
For additional information, refer to Section 412-03 Air Conditioning.
6. Add the required amount of oil to the A/C system depending on the
repair procedure.
For additional information, refer to Refrigerant Oil Adding in this section.
7. Evacuate and charge the A/C system.
For additional information, refer to Air conditioning (A/C) System Recovery, Evacuation and Charging in this section.
8. Carry out fluorescent dye leak detection test.

Item Description 1 RH (right-hand) end tank 2 Condenser core 3 LH (left-hand) end tank 4 Mounting brackets (4 off) 5 High pressure compressor discharge line connector block 6 High pressure liquid outlet line connector block 7 Receiver/Drier outlet pipe 8 Receiver/Drier inlet pipe 9 Receiver/Drier The condenser transfers heat from the refrigerant to the surrounding air to convert the high pressure vapor from the
compressor into a liquid. The condenser is installed immediately in front of the radiator. Two brackets on each end tank attach
the condenser to the end tanks of the radiator.

The condenser is classified as a sub-cooling condenser and consists of a fin and tube heat exchanger core installed between
two end tanks. Divisions in the end tanks separate the heat exchanger into a four pass upper (condenser) section and a two
pass lower (sub-cooler) section.

The LH end tank provides the connections to the high pressure line from the A/C compressor and the high pressure liquid line to the evaporator.
The RH end tank provides the connections to the receiver drier.
Receiver Drier

The receiver drier is integrated into the RH end tank of the condenser to remove solid impurities and moisture from the refrigerant. It also provides a reservoir for liquid refrigerant to accommodate changes of heat load at the evaporator.


NOTE: The receiver drier is part of the condenser assembly and is not serviceable separately.

Refrigerant entering the receiver drier passes through a filter and a desiccant pack, then collects in the base of the unit before
flowing through the outlet pipe back to the condenser. Condenser

Thermostatic Expansion Valve



Item Description 1 Metering valve 2 Housing 3 Diaphragm 4 Temperature sensor 5 Outlet passage from evaporator 6 Inlet passage to evaporator The thermostatic expansion valve meters the flow of refrigerant into the evaporator, to match the refrigerant flow with the
heat load of the air passing through the evaporator.

The thermostatic expansion valve is a block type valve located behind the heater assembly, and attached to the inlet and
outlet ports of the evaporator. The thermostatic expansion valve consists of an aluminium housing containing inlet and outlet
passages. A ball and spring metering valve is installed in the inlet passage and a temperature sensor is installed in the outlet
passage. The temperature sensor consists of a temperature sensitive tube connected to a diaphragm. The bottom end of the
temperature sensitive tube acts on the ball of the metering valve. Pressure on top of the diaphragm is controlled by the
evaporator outlet temperature conducted through the temperature sensitive tube. The bottom of the diaphragm senses
evaporator outlet pressure.

Liquid refrigerant flows through the metering valve into the evaporator. The restriction across the metering valve reduces the
pressure and temperature of the refrigerant. The restriction also changes the liquid stream of refrigerant into a fine spray, to
improve the evaporation process. As the refrigerant passes through the evaporator, it absorbs heat from the air flowing through
the evaporator. The increase in temperature causes the refrigerant to vaporise and increase in pressure.

The temperature and pressure of the refrigerant leaving the evaporator acts on the diaphragm and temperature sensitive tube,
which regulate the metering valve opening and so control the volume of refrigerant flowing through the evaporator. The warmer
the air flowing through the evaporator, the more heat available to evaporate refrigerant and thus the greater volume of
refrigerant allowed through the metering valve. www.JagDocs.com
