    Informational PurposesAn informational icon, calling your attention
    Note
    Close the right side regulator valve when the pressure reaches 26 psi and stabilizes. Fill time is 60 seconds.
  19. Wait 60 seconds to test pressure, and record the value of starting pressure.
  20. Wait another 4 minutes for pressure to settle, and then record the value of end pressure. Subtract the ending pressure from the starting pressure:
    • If the difference is greater than 0.200psi, check the hose, adapter, plug fittings, and check the regulator pressure, and then retest. If the difference is still greater than 0.200 psi, escalate a Toolbox session.
    • If the difference is 0.200 psi or less, continue the procedure.
  21. Disconnect the compressed air from the coolant pressure tester.
  22. Disconnect drive unit pressure test fixture from the coolant leak test adapter.

    Note
    Terminate after disabling the EPB Service Mode.
  33. On the touchscreen, touch Service Mode > Thermal > Refrigerant System > Stop Thermal Fill Drain, and allow the routine to complete.
  34. Select Cooling System > Coolant Purge, click Run, and allow the routine to complete.
    Informational PurposesAn informational icon, calling your attention
    Note
    • The routine will last for a while after the stop message displays. The coolant pumps are audible.
    • The test lasts for approximately 10 mins. Do not start another routine during this time.
    • Make sure that the vehicle is not in Drive. Putting the vehicle into Drive will stop this routine.
    • The speed in the test varies from 3500-6500 RPM (idle speed = ~1500 RPM) and the actuated valve varies between SERIES and PARALLEL.
    • If the speed hovers at 7000 RPM, it indicates the pumps are air locked. Perform the vacuum fill again. Continue to add the coolant and purge until the coolant level reaches between the NOM and MAX Lines on the bottle.
  35. Inspect the coolant level, top off as necessary, and then install the coolant bottle cap.
    Informational PurposesAn informational icon, calling your attention
    Note
    Ensure that the coolant level is at the "Max" line.
  36. On the touchscreen, touch Thermal > Actions, touch the START button next to Test Thermal Performance, click Run, and allow the routine to complete.
  37. Touch the START button next to Test HVAC Performance, click Run, and allow the routine to complete.
  38. Disable Service Mode. See Service Mode.
  39. Install the clips (x3) that secure the fresh air gutter assembly.
  40. Install the rear underhood apron. See Underhood Apron - Rear (Remove and Replace).
  41. Raise all windows and close all doors.
  42. Remove the lift arms from below the vehicle.
  43. Refer to the Alignment Requirement tables to determine whether an EPAS alignment check (EC) or four wheel alignment check (AC) is necessary. If performed, add the alignment check/adjust as a separate activity. See Alignment Requirement - Suspension.
