LIGHTING SYSTEM INITIALIZATION

Note:

  • Initialize the headlight swivel ECU after the headlight swivel ECU is replaced.

  • Initialize the headlight swivel ECU (set the zero point of the height control sensor in the headlight swivel ECU) after the vehicle height changes due to replacement of suspension components or after performing such operations as removal and reinstallation or replacement of the rear height control sensor sub-assembly RH.

  • Adjust the headlight aim after initializing the headlight swivel ECU (Click here).

      Removal and reinstallation of the headlight swivel ECU, replacement of the rear height control sensor sub-assembly RH, removal and reinstallation of the rear height control sensor sub-assembly RH, replacement of the suspension, etc. has been performed.

      Off → Continuously blinks N* times at 2 Hz.
      Tip:

      • *: The number of times that the indicator blinks is determined by the number of times the low beam headlights are turned on and off.
