AUTOMATIC HEADLIGHT BEAM LEVEL CONTROL SYSTEM INITIALIZATION

Note


  • Synchronize the vehicle information when the headlight leveling ECU assembly is replaced with a new one.

  • Initialize the headlight leveling ECU assembly when the headlight leveling ECU assembly is replaced.

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

  • Adjust the headlight aim after initializing the headlight leveling ECU assembly.
