HEIGHT CONTROL SENSOR SIGNAL INITIALIZATION

NOTICE:
  1. Initialize the height control sensor signal after the vehicle height changes due to replacement of the suspension or after performing such operations as removal and reinstallation or replacement of the rear height control sensor sub-assembly.
  2. When the headlight beam level control ECU is replaced, the initialization is also necessary.
  3. Adjust the headlight aim after initializing the headlight beam level control ECU (Click here).
  1. When a malfunction is detected in the headlight beam level control system, the height control sensor signal initialization is impossible. Perform troubleshooting before initialization.


1.PREPARE VEHICLE FOR INITIALIZATION

  1. Make sure for approximately 10 liters of fuel in the tank.

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

  3. Check that there are no passengers in the vehicle.

  4. Turn off the headlights.

2.CHECK WARNING LIGHT


    E121524E01

  1. Turn the ignition switch to the ON position, and check the headlight beam level control system warning light.

    OK:
    Condition
    		Specified Condition
    The headlight beam level control ECU is replaced with a new one.
    		Warning light continuously blinks twice at 2 Hz as shown in the illustration.
    Removal and reinstallation of the headlight beam level control ECU, replacement of the rear height control sensor sub-assembly, removal and reinstallation of the rear height control sensor sub-assembly, or replacement of the suspension, etc.
    		Warning light comes on for approximately 3 seconds, and then goes off (bulb check function).

    HINT:
    1. If the warning light does not come on when turning the ignition switch to the ON position, inspect and repair according to "PROBLEM SYMPTOMS TABLE" (Click here).
    2. If there is a problem with initialized data memorized in the headlight beam level control ECU, the warning light blinks twice at 2 Hz as shown in the illustration when the ignition switch is turned to the ON position.

3.INITIALIZATION


    E106867E12

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

    2. SST
    09843-18040  

  2. Flash the low beam headlights 3 times by turning the light control switch within 20 seconds after connecting the terminals.

    NOTICE:
    1. Turn the low beam headlights on or off at approximately 1-second intervals.
    2. Be sure to operate the light control switch from the outside of the vehicle.


    3. E121525E01

  3. Check the warning light.

    OK:
    Condition
    		Specified Condition
    The headlight beam level control ECU is replaced with a new one.
    		Blinks twice at 2 Hz → Blinks 3 times at 2 Hz, and then goes off (refer to illustration 1).
    Removal and reinstallation of the headlight beam level control ECU, replacement of the rear height control sensor sub-assembly, removal and reinstallation of the rear height control sensor sub-assembly, or replacement of the suspension, etc.
    		Off → Blinks 3 times at 2 Hz, and then goes off (refer to illustration 2).

    HINT:
    1. If calculated vehicle height is not between full-bound and full-rebound, the height control sensor initialization will end as abnormal termination, and the warning indicator will blink twice at 2 Hz continuously as shown in illustration 3. Disconnect the SST from the DLC3 and turn the ignition switch off. Then, restart from procedure 2.
    2. If initialization cannot be finished normally, check the LVL terminal circuit (Click here), or inspect and repair according to "PROBLEM SYMPTOMS TABLE" (Click here).
