8.7 Air conditioning system test without refrigerant
service
I
NOTE
The air conditioning 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 sys-
tem would lack the refrigerant remaining in the service hoses of the air
conditioning unit after the test. The "A/C system test" menu item has
been added to compensate for this loss.
I
NOTE
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 car-
ried out in the usual manner (the service hoses are drained by the
device).
1. First, fit the connections of the AirConServiceCenter to the vehicle
air conditioning system and open them.
2. Start the vehicle's engine and switch on the air conditioning system.
