|
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 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.
