|
|
|
Radiator outlet coolant temperature is higher than the nominal expected value under similar operating conditions.
|
The difference between radiator outlet coolant temperature and the expected temperature exceeds the threshold.
|
HVAC cabin cooling (air conditioning) and powertrain performance may be limited.
|
|
|
The Etherloop Generalized Gateway Right (EGGRIGHT3) controller area network (CAN) node detects low coolant flow based on the pump's flow model using the phase current.
|
The coolant flow index is less than 40.
|
Cabin climate control system air conditioning may be limited or unavailable. Powertrain performance may be limited.
|
|
|
The Supermanifold Vehicle Controller (VCSUPER) and Etherloop Generalized Gateway Right (EGGRIGHT3) controller area network (CAN) node detects an incomplete coolant air purge due to abnormal pump current profile or terminated purge routine.
|
The pump current profile is abnormal, or the purge routine is terminated before completion.
|
Cabin climate control system air conditioning may be limited or unavailable. Powertrain performance may be limited.
|
|
|
The VCSUPER and EGGRIGHT3 controller detects an air lock in the pump due to smaller than expected pump current values.
|
The pump current is below the minimum threshold value for more than 20 seconds.
|
Cabin climate control system air conditioning may be limited or unavailable. Powertrain performance may be limited.
|
|
|
The vehicle controller detects a refrigerant condition, such as low refrigerant or a blocked refrigerator filter, which may prevent the A/C compressor from operating as expected due to high suction superheat if no other heat pump modes are available.
|
The vehicle controller detects low refrigerant, a blocked refrigerant filter, or other refrigerant related conditions on the A/C compressor.
|
Cabin climate control system air conditioning and heating may be limited or unavailable. Battery heating and cooling performance may be limited.
|
|
|
The compressor power index is lower than expected, which typically indicates a condition affecting the compressor. This can also indicate a condition affecting the discharge or suction pressure sensors. The compressor power index measures the ratio of estimated nominal compressor power consumption against electrical power the compressor actually consumes. A low index value indicates the compressor is drawing / consuming significantly more power than a nominal compressor would be expected to consume.
|
The compressor power index, which compares expected compressor power consumption against actual consumption, drops below expected levels.
|
Thermal system may show reduced effectiveness. Cabin climate control performance may be limited, with cabin heating / cooling not performing at expected levels.
|
|
|
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.
|
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.
|
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.
|
|
|
Actual compressor power is lower than expected, as measured by the compressor power index.
|
This alert is set when compressor power index is above expected levels
|
Refrigerant compressor functionality may be affected, along with general HVAC performance.
|
|
|
The vehicle controller detects the actual A/C compressor power is lower than expected.
|
The A/C compressor power index is lower than expected.
|
Cabin climate control system air conditioning and heating may be limited or unavailable. Battery heating and cooling performance may be limited.
|
|
|
The vehicle controller detects a discrepancy in the estimated refrigerant flow rates between the A/C compressor and recirculation electronic expansion valve (EXV) as the estimated refrigerant flow index is higher than expected while the subcool is low.
|
The estimated refrigerant flow index is above the expected level, and the subcool is low.
|
Cabin climate control system air conditioning and heating may be limited or unavailable. Battery heating and cooling performance may be limited.
|
|
|
The flow index value is low at high subcool. The refrigerant flow rate through the electronic expansion valves (EXV) is not meeting the expected value when compared to the compressor refrigerant flow rate.
|
The vehicle detects that refrigerant flow index is below expected levels and subcool is high.
|
The thermal system may not perform as expected.
