- If the headlight switch signal from the column switch turns on, the front-ECU makes the headlights illuminate. Whenever the headlights illuminate, the low-beam lights illuminate due to the headlight dimmer switch automatic resetting function.
- If the SWS communication line is defective, the low-beam headlights will illuminate by using other signal line (headlight back-up circuit).
