System Description [11/2016 - ]

When the light control switch is in the AUTO position, the automatic light control system detects ambient light levels and controls the low beam headlights, parking lights, taillights and license plate lights.

The light auto turn-off system is used to prevent the exterior lights (headlights, front fog lights, taillights, parking lights, license plate lights, front side marker lights and rear side marker lights) from being accidentally left on.

• This system has the following functions.

The daytime running light system is designed to automatically illuminate the daytime running lights during the daytime to make the vehicle more visible to other vehicles.

• This system is controlled by the main body ECU (multiplex network body ECU) and semiconductor pwr integration ECU. The main body ECU (multiplex network body ECU) transmits a turn on signal to the semiconductor pwr integration ECU, which illuminates the daytime running lights (headlight assembly) *1 or low-intensity high beam headlights*2.
  • *1: for LED Type DRL
  • *2: for Bulb Type DRL
• This system is enabled when the following conditions are met:
  • The power switch is on (READY).
  • The light control switch is in the off, tail or AUTO position (and the low beam headlights are not turned on via the automatic light control system). (w/o DRL OFF Switch)
  • The light control switch is in the tail or AUTO position (and the low beam headlights are not turned on via the automatic light control system). (w/ DRL OFF Switch)
  • The parking brake switch is off.

1. General
   • The door mirror foot light system consists primarily of the fade-in/fade-out function and timer illumination function.
   • This system is controlled by the outer mirror control ECU assembly for each mirror and main body ECU (multiplex network body ECU). The main body ECU (multiplex network body ECU) sends door mirror foot light on/off demand signals to the outer mirror control ECU assembly. According to various information, the outer mirror control ECU assembly performs fade-in/fade-out control of the door mirror foot lights.
2. The door mirror foot light system has the following control functions:
