Air conditioning system test without refrigerant
service
I
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
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.
3. Press the cursor key
or
to access the basic menu.
4. In the basic menu, use the cursor keys
or
to select
“Other selections”
:
5. Press
ENTER
to confirm.
6. Use the cursor keys
or
to select
“A/C system test”
:
✓
A prompt appears asking you to check the air conditioning system:
7. Check the high and low pressure of the air conditioning system in
accordance with the manufacturer's specifications.
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.
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).
