Inspection and Verification


WARNING: Servicing must be carried out by personnel familiar with both vehicle system and the charging and testing
equipment. All operations must be carried out in a well ventilated area away from open flame and heat sources.


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.


NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
1. Verify the customer concern

3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step

4. If the cause is not visually evident, verify the symptom and refer to the Symptom Chart, alternatively check for
Diagnostic Trouble Codes (DTCs) and refer to the DTC Index

5. Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific
customer complaint and carry out the recommendations as required

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
