|
The front vehicle controller (VCFRONT) detects the electrical current flowing through the power conversion system (PCS) eFuse has equaled or exceeded 200A during the previous 10 milliseconds.
|
The PCS eFuse current value equals or exceeds 200A during the previous 10 milliseconds.
|
The eFuse circuit may open (trip), interrupting low voltage power supply to the PCS. This could make PCS functions limited or unavailable, and may interrupt precharging of the high voltage (HV) bus .
|
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

|
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

|
|
A Battery Monitoring Board (BMB) device has detected an over voltage condition
|
Any BMB device in the daisy chain detects an over voltage condition
|
May indicate the battery pack is operating under unintended conditions. This alert may result in loss of pack power

|
The eFuse circuit may open (trip), interrupting power supply to the EPAS3P and making power steering limited or unavailable.
|
No
|
|
|
The front vehicle controller (VCFRONT) detects the electrical current flowing through the secondary electronic power assisted steering (EPAS3S) eFuse has equaled or exceeded 100A during the previous 10 milliseconds.
|
The EPAS3S eFuse current value equals or exceeds 100A during the previous 10 milliseconds.
|
The eFuse circuit may open (trip), interrupting power supply to EPAS3S and making power steering limited or unavailable.
|
No
|
|
|
The front vehicle controller (VCFRONT) detects the electrical current flowing through the electromechanical brake booster (iBooster) eFuse has equaled or exceeded 100A during the previous 10 milliseconds.
|
The iBooster eFuse current value equals or exceeds 100A during the previous 10 milliseconds.
|
The eFuse circuit may open (trip), interrupting power supply to iBooster and making brake functionality limited.
|
No
|
|
|
The front vehicle controller (VCFRONT) detects the electrical current flowing through the electronic stability program (ESP) eFuse has equaled or exceeded 100A during the previous 10 milliseconds.
|
The ESP eFuse current value equals or exceeds 100A during the previous 10 milliseconds.
|
The eFuse circuit may open (trip), interrupting power supply to ESP and making vehicle stability control limited.

|
|
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
|
|
|
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
|
|
|
The vehicle controller detects output voltage from the air compressor for the air suspension system when none is expected. The vehicle controller's fused high current eFuse circuit will be used to deenergize the air compressor.
|
Air compressor output voltage is detected when the air compressor has been requested off.
|
The air compressor for the air suspension system is unavailable, making air suspension functionality limited or unavailable.
|
No
|
|
|
The front vehicle controller (VCFRONT) detects the front trunk (also known as the frunk) secondary latch is experiencing an undercurrent condition.
|
The frunk secondary latch draws less current than expected.
|
The frunk secondary latch may be disconnected.
|
No
|
|
|
The front vehicle controller (VCFRONT) detects the front trunk (also known as the frunk) secondary latch is experiencing an overcurrent condition.
|
The frunk secondary latch draws more current than expected.
|
The frunk may not open.
|
No
|
|
|
The front vehicle controller (VCFRONT) detects the front trunk (also known as the frunk) emergency release button was pressed while the frunk was closed.
|
The frunk emergency release is pressed while the frunk is closed.
|
If the vehicle is stationary, the frunk will open. If the vehicle is in motion, the frunk will release to the ajar (or secondary) position.
