Description
Low flow index has been detected at high subcool at steady state or suction superheat is found to be abnormally low, which indicates that air bubbles are circulating in the refrigerant system.
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.
Set Condition
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.
Clear Condition
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.
