13.7 Testing the air conditioning system without refrigerant service
Note The air conditioning system can only be tested on vehicles with a low pressure port and a high
pressure port or with a low pressure port only.
If you only test the function of a vehicle air conditioning system without drawing off and recycling the refrigerant,
the vehicle air conditioning system would lack the refrigerant remaining in the service hoses of the air conditioner
after the test. The A/C system test menu item has been added to compensate for this loss.
The existing standard function processes Short selection and Free selection already have a compensation
function for service hoses, which means the final air conditioning function test can be carried out in the usual man-
ner (the service hoses are drained by the A/C service unit).
1. First, fit the connections of the A/C service unit to the vehicle air conditioning system and open them.
2. Start the vehicle's engine and switch on the air conditioning system.
