Work Order Description

Nominal Value

Check: Vehicle Configuration

Is the following information correct for the actual vehicle?

Check: Refrigerant Circuit

Note:

Do not check the air conditioning system in immediate vicinity of walls (Distance approximately 2 m ), in order to guarantee a sufficient air circulation at the condenser.

• Connect service station to the air conditioning system
• Engine idling
• Set desired temperature passenger compartment to COLD
  (counter-clock wise to stop)
• Blower stage 4 selected
• Air conditioning system switch ON
• Read high pressure gauge

Air conditioning system pressure is greater than 1300 kPa ( 13 bar )

Check: Adjacent System

• Is at least one cooling fan running?

.

Check: Refrigerant Circuit

Note:

Before discharging the air conditioning system, check refrigerant circuit for leakage.

Especially the connection to the expansion valve has to be checked.

• Ignition OFF
• Discharge, evacuate and fill air conditioning system with correct refrigerant charge
• After successful test/fault repair proceed to the next test step

Check: Vehicle Configuration

Is the following information correct for the actual vehicle?
