What triggers it
The vehicle detects at least two of the following: low flow index at high subcool on either Chiller Only or Evap Only modes or abnormally low suction superheat.
When it clears
The alert will clear once the vehicle wakes from Sleep mode or when low flow index is no longer observed at high subcool and suction superheat is no longer abnormally low.
Potential impact
The thermal system may not perform as expected and the electronic expansion valves (EXV) will open wider to accommodate the air bubbles in the system.
