CAUTION
Model
Y thermal management components operate under very
tight specifications and can malfunction if Service procedures are not carefully
followed. DO NOT rely on past
experience with other thermal management systems; read through the Service Manual and do
not deviate from the
instructions.

Remove
- Set up the AC machine.
- Remove the underhood storage unit. See Underhood Storage Unit (Remove and Replace).
- Connect to vehicle using Toolbox 3.0.
- In Toolbox, click Actions/Autodiag, and then search for "Thermal".
-
Click Thermal
Fluid Fill/Drain, and then click Run
and allow the routine to complete.
NoteSelect "X" at top right of window to close once complete, Thermal Fluid Fill/Drain routine has a 5 hour time limit, After 5 hours EXV's will close and routine must be performed again, Verify EXV positions are open VIA Garage >Thermal > Refrigerant loop EXV, Verify LCC, CC Left, Evap, CC Right, Chiller are all at ~100%. Recirc is at ~20%, LCC Solenoid is OPENED
- Disconnect 12V power. See 12V/LV Power (Disconnect and Connect).
- Remove HSD cable from Ethernet port to disconnect Toolbox 3.0 from vehicle.
-
Remove caps from low side
and high side AC ports.
-
Connect hoses to vehicle and
perform AC recovery
NoteTouch time only, Connect couplers to vehicle, Open couplers by turning clockwise, Open Machine valves, Note the amount of refrigerant and oil recovered, If drained oil level increased more than 30 mL refer to drained oil loss chart.
-
Overlap from AC refrigerant
recovery
-
Remove AC hoses from
vehicle
-
Remove the bolt that
attaches the supermanifold-to-compressor A/C line to the
supermanifold.
Tip: Use of the following tool(s) is recommended:
- 13 mm socket
- Flex head ratchet/flex head torque wrench
- 6 in extension
-
Remove the
supermanifold-to-compressor A/C line from the supermanifold, and then hang
it on the underhood storage unit support beam using an s-hook.
NoteCarefully position the line so that oil does not drip out.
-
Release the connector locks,
and then disconnect the electrical connectors leading up to the desired EXV.
Follow the disconnect order in the example image.
CAUTIONDO NOT push down on the red locking tab. Pull the tab away from the connector until the connector is unlocked, and then continue pulling to release the connector.NoteThe disconnect order is for ease of access.
-
Release the locking tab, and
then disconnect the electrical connector from the desired EXV.
CAUTIONDO NOT push down on the red locking tab. Pull the tab away from the connector until the connector is unlocked, and then continue pulling to release the connector.
- Remove the supermanifold harness from the supermanifold and rest it on the frunk support beam.
- Use a pick to pull the locking tab downward, and then pull toward the front of the vehicle to remove the EXV coil.
-
Remove the EXV valve body
from the supermanifold.
Tip: Use of the following tool(s) is recommended:
- 1588745-00-A - Expansion Valve Socket, 28mm, 1/2" Drive
- 6 in extension
- Flex head ratchet/flex head torque wrench
Install
- Lubricate the EXV threads and O-rings with the appropriate type of A/C oil. See Fluids and Capacities for A/C oil specifications. Then hand-start the valve into the supermanifold.
-
Fully torque the EXV on the
supermanifold.Tip: Use of the following tool(s) is recommended:
- 1588745-00-A - Expansion Valve Socket, 28mm, 1/2" Drive
- 6 in extension
- Flex head ratchet/flex head torque wrench
-
Install the EXV coil onto
the EXV.
NoteAlign the locking tab on the connector assembly with the recess in the EXV.
- Connect the electrical connectors that were disconnected during removal, and then engage the connector locks.
- Install new seal washers on the supermanifold side of the supermanifold-to-compressor A/C line, and then lubricate the washers with a small amount of the appropriate type of A/C oil. See Fluids and Capacities for A/C oil specifications.
- Position the supermanifold-to-compressor A/C line on the supermanifold, and then hand tighten the bolt that attaches the A/C line to the supermanifold.
-
Tighten the bolt that
attaches the A/C line to the supermanifold.Tip: Use of the following tool(s) is recommended:
- 13 mm socket
- Flex head ratchet/flex head torque wrench
- 6 in extension
-
Reconnect the AC hoses to
the vehicle.
-
Perform AC vacuum.
NoteTouch time only, 2 minute leak test, 15 minute vacuum
- Overlap from AC vacuum.
-
Remove low side AC hose from
supermanifold to HVAC AC line assembly.
-
Use oil injector to add
measured amount of oil back to the system.
NoteUse calculated oil lost measurement and add new oil of the appropriate type into the system. See Fluids and Capacities for A/C oil specifications. If more than 30 ml drained out during recovery, refer to the drained oil loss chart.
-
Install low side AC hose to
supermanifold to HVAC AC line assembly.
-
Perform AC refrigerant
refill.
NoteRecharge refrigerant to 1.02 kg (1020g). For Robinair AC machines press ESC to NOT ACCEPT the step to clear out residual oil. Once complete press next to start End of Charge process.
-
Perform step 1 for End of
Charge process.
NoteClose high and low machine valves. Press next to continue.
-
Connect first responder loop
and 12V negative terminal.
Note1x nut, 10mm, 6 Nm, 1x connector, Engage locking tab, Connect FRL first before connecting 12V to avoid damage to car computer
- Connect to vehicle using Toolbox 3.0.
- In Toolbox, click the Actions/Autodiag tab, and then search for "commissioning".
-
Click
TEST-SELF_VCFRONT_X_HEAT-PUMP-COMMISSIONINGSearch for routine in ToolboxThermal / Refrigerant System - Run Heat Pump Commissioninghv / Front Drive Inverter Replacement - Heatpump commissioning, and
then click Run and allow the routine to
complete.
NoteIf this routine is not run after entering Thermal Drain/Fill mode, the AC compressor operation will be blocked, Select ‘X’ at top right of window to close once complete.
-
Proceed with steps 2-4 for
End of Charge process and follow instructions displayed on AC Machine.
NoteTurn AC on, Temp setting LO, Panel mode on, Fresh air mode on, Blower speed set to 3, Verify Discharge pressure does not exceed 26 bar and Suction pressure is not below 1.15 bar, Turn AC OFF, allow pressures to stabilize and remove high side hose.
