Preparations prior testing the vehicle
•
The vehicle should be at operating temperature.
•
Set the air conditioning system to maximum cold.
•
Set the speed of the blower on maximum.
•
Only use vents in the centre of the car (close others).
•
The airflow should be positioned and set at face vent level. Position a temperature
probe in the centre allowing you to measure the air outlet temperature.
•
Connect a gauge or A/C service station to allow you to view the operating
low and high side system pressures.
•
Disconnect the plug on the A/C compressor control valve or control valve harness.
Connect the appropriate CLT1 Universal, VAG-group or Denso harness.
•
Connect the simulator to the disconnected control valve plug.

General Advice
The 12V battery power supply should be maintained for the protection of the test
equipment and the compressor.
