Recovery
- Perform a calibration check of the A/C machine. Refer to the A/C machine operator’s manual for instructions on how to perform a calibration check of the A/C machine. If the machine fails the calibration check, do not use the machine until a service representative has calibrated the A/C machine.
- Inspect the entire length of the hoses and fittings for degradation, cracks, or damage. Make sure that the condition of the hoses and fittings is such that they will not leak when in service.
- Inspect the A/C machine’s power supply cord and plug that they are not damaged and the insulation has not been compromised in any way.
- Make sure to use the appropriate type of A/C oil.
- Set up the A/C machine.
- Remove the rear underhood apron. See Underhood Apron - Rear (Remove and Replace).
- Remove the cabin intake duct. See Assembly - Fresh Air Gutter - HVAC (Remove and Replace).
- Remove the access panel. See Cover - Hood Latch (Remove and Replace).
- Remove the underhood storage unit. See Underhood Storage Unit (Remove and Replace).
- Unlock the vehicle gateway. See Gateway Unlock.
- On the touchscreen, touch Run to start the "Start Thermal Fill Drain (Refrigerant Only)" routine. and select
-
Wear appropriate personal protective
equipment.
WarningR134a and r1234yf refrigerants are dangerous liquids and can cause serious injury if handled improperly. When recycling or recharging the air conditioning system, you must wear appropriate personal protective equipment (PPE), including face shields, heat-resistant gloves, rubber boots, aprons or waterproof overalls.
- Remove the caps from the A/C high pressure and low pressure ports.
-
Connect the red high
pressure hose to the A/C high pressure port, and the blue low pressure hose
to the A/C low pressure port.
NoteThe high pressure and low pressure ports are of different sizes, and match the hose couplers accordingly.
- Follow the A/C machine instructions for recovering refrigerant and oil from the vehicle.
-
Take note of or print the
amount of refrigerant (approximately 1000 - 1040 g) and oil (approximately
8.87 ml) recovered after recovery is complete.
NoteThe A/C machine chimes when recovery is complete.
Vacuum Leak Test and Oil Injection
-
On the A/C machine, touch
ENTER, touch , set the vacuum time to 15 min, then touch ENTER, and follow the A/C
machine instructions to perform A/C vacuum leak test.
CAUTIONMake sure vacuum leak test is passed before proceeding to the next step.NoteThe A/C machine chimes when vacuum leak test is complete.
- Remove the blue low pressure hose from the A/C low pressure port.
-
Measure the quantity of oil
recovered from the vehicle's A/C system by comparing the level change in the
oil recovery tank. Refer to the table below to determine the quantity of oil
to add to the A/C system during recharge, assuming that no components are
being replaced.

Recharge
-
Touch ENTER, touch , and then follow the A/C machine instructions to perform an A/C
refrigerant recharge.
NoteEnter refrigerant account noted in the A/C recovery.NoteThe A/C machine chimes when recharge is complete.
- Remove the red high pressure hose from the A/C high pressure port, and the blue low pressure hose from the A/C low pressure port.
- Install the caps on the A/C high pressure and low pressure ports.
