Normal pressures for a correctly charged and working system are 1.0 bar to 2.0 bar (low) and 11.0 bar to 15.0 bar (high).
Normal temperature (measured at the center air vent) for a correctly charged and working system is -7°C to -2°C when
ambient temperature is 20°C. 1 Close the valves on the air conditioning station 2 Connect the air conditioning station to the vehicle charging ports 3 Open all doors and the tailgate 4 Start the engine 5 Set the temperature to the lowest setting (all zones) 6 Set the fan speed to maximum 7 Set the recirculate switch to off 8 Insert a temperature probe into the centre air vent 9 Raise engine speed to 1500rpm and maintain this speed for 5 minutes 10 Check the temperature value 11 Check the pressure values Are the pressure readings stable and in the green 'normal' region of the gauge? Yes
Air conditioning system operating normally No
Air conditioning system fault present. GO to Pinpoint Test C.

Refer to the relevant section of the workshop manual and evacuate and recharge the air conditioning
system. GO to Pinpoint Test B. No
GO to C3. C3: GAUGE TEST 3 NOTES:

This test is performed with the engine running and the air conditioning set to on.
Normal pressures for a correctly charged and working system are 1.0 bar to 2.0 bar (low) and 11.0 bar to 15.0 bar (high). 1 Check the pressure values Are the pressure gauge readings too low? Yes
GO to C4. No
GO to C6. C4: GAUGE TEST 4
NOTE: This test is performed with the engine not running. 1 Stop the engine 2 Using the manufacturer approved refrigerant leak detector, check for a refrigerant leak Was a refrigerant leak detected? Yes
Refer to the relevant section of the workshop manual and recover the refrigerant. Repair as necessary.
Evacuate and recharge the air conditioning system. GO to Pinpoint Test B. No
GO to C5. C5: GAUGE TEST 5
NOTE: This test is performed with the engine not running. 1 Refer to the relevant section of the workshop manual and recover the refrigerant Was the weight of the recovered refrigerant less than specified for the air conditioning system? Yes
Refer to the relevant section of the workshop manual and evacuate and recharge the air conditioning
system. GO to Pinpoint Test B. No
Install a new receiver drier. Refer to the relevant section of the workshop manual and evacuate and recharge the air conditioning system. GO to Pinpoint Test B. C6: GAUGE TEST 6 NOTES:

This test is performed with the engine running and the air conditioning set to on.
Normal pressures for a correctly charged and working system are 1.0 bar to 2.0 bar (low) and 11.0 bar to 15.0 bar (high).

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.
