Left and right headlamps report simultaneous matrix manager, LED, High Side Driver (HSD), or Boolean status errors indicating a condition affecting functionality of both headlamps.
|
For both headlamps, the SSL100 pixel matrix detects non-functional pixels or has communication issues, or the voltage measured across the Lowbeam Prefield, DRL segments, side marker, 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.
