| Signal Name | Description | Condition | Impact |
|---|---|---|---|
|
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 high.
|
The estimated refrigerant flow index is above the expected level, and the subcool is high.
|
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 the isentropic check for the refrigerant discharge temperature (TD) is unsuccessful, indicating the A/C compressor mass flow rate is below the expected level.
|
The isentropic check for the TD is unsuccessful.
|
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 that the Thermal Fill Drain service routine is being run while the vehicle is in Drive.
|
The Thermal Fill Drain service routine is run.
|
Cabin climate control system air conditioning and heating may be limited or unavailable. Powertrain performance may be limited.
|
|
|
The refrigerant system has not been commissioned or has been decommissioned by the Thermal Fill Drain service routine.
|
The Thermal Fill Drain service routine is run.
|
Powertrain and HVAC performance will be limited, the compressor will be limited to 2000rpm.
|
|
|
The vehicle controller detects a condition(s) affecting the Thermal Management System that prevents it from performing as designed.
|
The vehicle controller detects a condition(s) affecting the Thermal Management System. Alert log signal data for the cabinHVACUnavailableContext alert should provide more information on the specific condition(s) detected.
|
Cabin climate control system air conditioning may be limited or unavailable. Powertrain performance may be limited.
|
|
|
Condition(s) affecting the thermal management system have reduced cabin heating and/or cooling performance or made cabin heating and/or cooling unavailable.
|
May set due to many possible conditions affecting thermal management system functionality. Alert log signal data should provide information on specific condition(s).
|
Cabin heating and/or cooling performance may be limited, or cabin heating and/or cooling may be unavailable.
|
|
|
HV Battery Discharge routine is running with reduced power, the battery will discharge at a lower rate than expected.
|
System condition are not met for full power discharge of the HV battery.
|
Refer to HV Battery Discharge routine documentation.
|
|
|
HV Battery Discharge routine exited, the HV Battery Discharge will not run until reset conditions are met.
|
System condition for the HV Battery Discharge routine are not met and the routine is exiting.
|
Refer to HV Battery Discharge routine documentation.
|
|
|
HV Battery Discharge routine entered, expect the HV Battery Discharge routine to run.
|
System trigger condition for the HV Battery Discharge routine was met and the routine attempted to start.
|
Refer to HV Battery Discharge routine documentation.
|
|
|
The vehicle controller detects the vehicle is not factory gated or the refrigerant is not filled, causing the compressor to be unavailable and the refrigerant valves (solenoid or electronic expansion valves (EXV)) to remain open.
|
May set due to any of the following: (1) vehicle is not factory gated; (2) refrigerant is not filled; (3) refrigerant fill / drain routine is active.
|
Cabin climate control system air conditioning may be limited or unavailable. Powertrain performance may be limited.
|
|
|
Difference between the discharge pressure and liquid pressure (Pd-Pl) increased. Discharge lines or Liquid Cooled Condenser (LCC) may be blocked.
|
Pd-Pl is greater than 6 bar for 5 consecutive seconds.
|
Thermal performance is degraded.
|
|
|
The vehicle controller detects the vehicle is not factory gated or the coolant is not filled, causing the coolant pumps to turn off and the coolant valve to be in Series or No Bypass mode.
|
May set due to any of the following: (1) vehicle is not factory gated; (2) coolant is not filled; (3) coolant fill / drain routine is active.
|
Cabin climate control system air conditioning may be limited or unavailable. Powertrain performance may be limited.
|
|
|
Coolant flow is compromised and not flowing to components as expected.
|
Coolant system detects one or more conditions preventing nominal coolant flow to components.
|
Components within the coolant system are receiving significantly reduced or no coolant flow.
|
|
|
The vehicle controller detects the coolant valve actuator is clocked incorrectly on the coolant valve.
|
The coolant valve actuator is clocked incorrectly on the coolant valve.
|
Powertrain performance may be limited.
|
|
|
The vehicle controller detects the battery coolant temperature sensor is reporting an incorrect value.

|
Powertrain performance may be limited.
|
|
|
One or more expected Controller Area Network (CAN) messages from the Audio Digital Signal Processor (ADSP) electronic control unit (ECU) was not received. ADSP data from accelerometers may be unavailable.
|
One or more expected CAN messages from the ADSP is not successfully received. May be due to missing message(s), message reception rate error, or invalid checksum / counter error (message is too short / long, the checksum does not match, or unexpected sequence errors are present).
|
