|
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 specified device may not work as expected.
|
Current device configuration doesn't match the desired configuration.
|
The specified device may not work as expected. A reset will clear the fault and correctly configure the device.
|
|
|

|
|
|
Chiller coolant pumps will not operate while restarting.
|
Chiller coolant pumps have recovered from a fault, and is restarting
|
Powertrain performance will be limited, coolant flow will be reduced.
|
|
|
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.
|
|
|
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.
|
|
|
One or more of the messages the vehicle controller receives periodically from the front passenger seat controller (VCSEATP) is not received, indicating the VCSEATP may be unavailable (MIA).
|
One or more of the expected messages from the VCSEATP is not received.
|
Front passenger seat features depending on VCSEATP functionality, including seat buckle and heating pad, may be limited or unavailable.
|
|
|
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.
|
|
|
A fault has been detected with the right tail light.
|
The right tail light driver has reported a fault.
|
The right tail light may not be working.
|
|
|
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.
