AFS (ADAPTIVE FRONT-LIGHTING SYSTEM) INITIALIZATION

Note


  • Synchronize the vehicle information when the AFS ECU (headlight swivel ECU assembly) is replaced with a new one.

  • Initialize the AFS ECU (headlight swivel ECU assembly) when the AFS ECU (headlight swivel ECU assembly) is replaced.

  • Initialize the AFS ECU (headlight swivel ECU assembly) (set the zero point of the height control sensor in the AFS ECU (headlight swivel 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 AFS ECU (headlight swivel ECU assembly).

  • When a malfunction is detected in the AFS (Adaptive Front-lighting System), height control sensor signal initialization is impossible. Perform troubleshooting before initialization.


  1. SYNCHRONIZE VEHICLE INFORMATION


    1. When using the GTS:


      1. Turn the power switch off.

      2. Connect the GTS to the DLC3.

      3. A01KRI4C02
        *1 AFS OFF Indicator Light

        Turn the power switch on (IG), and check that the AFS OFF indicator light continuously blinks at 0.5 Hz.

      4. Enter the following menus: Body Electrical / AFS / Utility / ECU Information Sync.


        Body Electrical > AFS > Utility
        Tester Display
        ECU Information Sync

      5. Check what is displayed on the screen of the GTS and press "Next".

      6. Check that the AFS OFF indicator light continuously blinks 6 times at 2 Hz.

      7. Press "Exit" and turn the power switch off.

        Note

        After synchronizing vehicle information, initialize the AFS ECU (headlight swivel ECU assembly).

    2. When not using the GTS:


      1. A01KRI4C02
        *1 AFS OFF Indicator Light

        Turn the power switch on (IG), and check that the AFS OFF indicator light continuously blinks at 0.5 Hz.

      2. Turn the low beam headlights on and off 8 times using the light control switch within 20 seconds after turning the power switch on (IG).

        Tech Tips

        If the light control switch operation cannot be finished within 20 seconds, turn the power switch off. Then, turn the power switch on (IG) and restart again.

        Note

        Turn the low beam headlights on and off at less than 2-second intervals.

      3. Check that the AFS OFF indicator light continuously blinks 6 times at 2 Hz.

      4. Turn the power switch off.

        Note

        After synchronizing vehicle information, initialize the AFS ECU (headlight swivel ECU assembly).

  2. AFS ECU (HEADLIGHT SWIVEL ECU ASSEMBLY) INITIALIZATION PROCEDURE


    1. Prepare vehicle for initialization


      1. Unload the trunk and vehicle, ensuring that the spare tire, tools and jack are in their original positions.

      2. Check that there are no occupants in the vehicle.

      3. Turn off the headlights.

      4. Stop the vehicle on a level surface and keep the vehicle height unchanged.

    2. A01KRI4C02
      *1 AFS OFF Indicator Light

      Check AFS OFF indicator light


      1. Turn the power switch on (IG), and check the indicator light.

        Tech Tips

        If the indicator light does not come on when turning the power switch on (IG), perform troubleshooting according to Problem Symptoms Table.

      2. Initialization


        1. A01KSMME45

          Connect SST to terminals 4 (CG) and 8 (LVL) of the DLC3.

          SST
          09843-18040
        2. A01KRGTC02
        3. *1 Fuel Receiver Gauge

Turn the low beam headlights on and off using the light control switch within 20 seconds after connecting the terminals.

Tech Tips

The number of times the low beam headlights need to be turned on and off is determined by the present fuel level as shown below.

Fuel Level Number of Times to Turn Low Beam Headlights On and Off
Fuel level is within A range. 1
Fuel level is within B range. 2
Fuel level is within C range. 3
Fuel level is within D range. 4
Fuel level is within E range. 5

Note


  • Check the indicator light.

    Tech Tips


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

    • If initialization does not finish normally, disconnect SST from the DLC3 and turn the power switch off. Then, restart initialization from procedure (a).

  • Check initialization finishes normally and turn the power switch off.
