The front vehicle controller (VCFRONT) detects the electrical current flowing through the power conversion system (PCS) eFuse has equaled or exceeded a current slope value (rate of change) of 120A per millisecond.
|
The PCS eFuse current slope value equals or exceeds 120A per millisecond.
|
The eFuse circuit may open (trip), interrupting low voltage power supply to the PCS. This could make PCS functions limited or unavailable, and could interrupt precharging of the high voltage (HV) bus .

No washer fluid, or insufficient washer fluid, available for use with wipers to clean the windshield.
|
No
|

System condition for the HV Battery Discharge routine are not met and the routine is exiting.
|
Refer to HV Battery Discharge routine documentation.

|
The eFuse application-specific integrated circuit (ASIC) on the vehicle controller is in an unexpected state
|
Vehicle controller eFuse ASIC is not in the requested state
|
Vehicle Controller eFuse ASIC may not turn on or off as expected
|
No
|
|
|
A pack serial number (SN) change has been detected which requires an ECU reset to re-initialize data from non-volatile memory (NVM)
|
A valid pack SN has been read with does not match the pack SN associated with the NVM data used after ECU reset
|
The NVM data used during initialization may not match with the swapped pack. Pack vitals, such as State of Charge, may be inaccurate
|
No
|
|
|
The vehicle controller detects the front trunk (also known as the frunk) sensor requires service as a condition affecting functionality has been detected on one or more of the frunk latch switches.
|
May set due to any of the following: (1) one of the switches is pressed while the other is not pressed; (2) one or more of the frunk latch switches on the frunk sensor are shorted, disconnected, or in an indeterminate voltage range.
|
The frunk may not function as expected. For example, the user interface (UI) on the center display may show the frunk as open when it is actually closed.
|
No
|
|
|
The pack serial number (SN) is invalid and is not supported for tracking in non-volatile memory (NVM)
|
An invalid pack SN has been read
|
Pack data will not be tracked in NVM. Pack vitals, such as State of Charge, may be inaccurate after ECU resets
|
No
|
|
|
An internal condition affecting left headlamp functionality has been detected - certain light functions or the headlamp fan may be degraded or disabled
|
The SSL100 pixel matrix detects non-functional pixels or has communication issues, or the voltage measured across the boost rail, Lowbeam Prefield, DRL1/2/3, or Turn LEDs is out of range, or the LED drivers in the ECU have reported status flags, or certain values programmed in the SSL100 EEPROM are out of range, or the fan current is out of range.
|
Certain light functions or the headlamp fan may be degraded or disabled. These functions will retry after the next headlamp power cycle (which occurs during sleep)
|
No
|
|
|
The front vehicle controller (VCFRONT) detects an invalid coolant pump configuration. Powertrain thermal management and performance may be limited. A VCFRONT reset will typically clear the alert by correctly configuring the pump.
|
The coolant pump configuration detected does not match the configuration expected by VCFRONT.
|
The coolant pump may not work as expected, limiting powertrain thermal management and performance.
|
No
|
|
|
A Battery Monitoring Board (BMB) device has detected an under voltage condition
|
Any BMB device in the daisy chain detects an under voltage condition
|
May indicate the battery pack is operating under unintended conditions. This alert may result in loss of pack power
|
No
|
|
|
An internal condition affecting right headlamp functionality has been detected - certain light functions or the headlamp fan may be degraded or disabled
|
The SSL100 pixel matrix detects non-functional pixels or has communication issues, or the voltage measured across the boost rail, Lowbeam Prefield, DRL1/2/3, or Turn LEDs is out of range, or the LED drivers in the ECU have reported status flags, or certain values programmed in the SSL100 EEPROM are out of range, or the fan current is out of range.
|
Certain light functions or the headlamp fan may be degraded or disabled. These functions will retry after the next headlamp power cycle (which occurs during sleep)
|
No
