correctly.
Non regulated air conditioning.
With the air conditioning and ventilation on
maximum and the engine running at idle,
check that the compressor operates.
Does the compressor operate?
Connect the XR25 and enter G21*
(direct compressor control).
Does the compressor operate?
Check the pressure of the coolant circuit.
The compressor should cut in for:
- low pressure≥ 2 bars,
- high pressure≤ 28 bars.
Is this correct?
Check the wiring between
the heating and ventilation computer
and the compressor clutch.
Repair if necessary.
Check that the components which were removed are connected correctly.
Check that the system operates correctly.
