AUTOMATIC HEADLIGHT BEAM LEVEL CONTROL SYSTEM INITIALIZATION

HEIGHT CONTROL SENSOR SIGNAL INITIALIZATION (for Segment Display Type)

1. PREPARE VEHICLE FOR INITIALIZATION (for Segment Display Type)

1. Unload the trunk and vehicle, and make sure 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. CHECK WARNING LIGHT (for Segment Display Type)

1. 

   *a	Headlight Beam Level Control System Warning Light

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

   OK

   Condition	Specified Condition
   The headlight leveling ECU is replaced with a new one.	Warning light continuously blinks 6 times at 2 Hz.
   Removal and reinstallation of the headlight leveling ECU, replacement of the rear height control sensor, removal and reinstallation of the rear height control sensor, replacement of the suspension, etc.	Warning light comes on for approximately 3 seconds, and then turns off (bulb check function).

   Tip:

3. INITIALIZATION (for Segment Display Type)

1. 

   *a	Front view of DLC3

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

2. 

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

   Tip:

   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 range A.	1
   Fuel level is within range B.	2
   Fuel level is within range C.	3
   Fuel level is within range D.	4
   Fuel level is within range E.	5

   Note:

   • Turn the low beam headlights on and off at approximately 3-second intervals.

   • Be sure to operate the headlight dimmer switch from the outside of the vehicle.

3. Check the warning light.

   OK

   Condition	Specified Condition
   The headlight leveling ECU is replaced with a new one.	Blinks 6 times at 2 Hz → Blinks 3 times at 2 Hz, and then turns off.
   Removal and reinstallation of the headlight leveling ECU, replacement of the rear height control sensor, removal and reinstallation of the rear height control sensor, replacement of the suspension, etc.	Off → Blinks 3 times at 2 Hz, and then turns off

   Tip:

   • If the calculated vehicle height is not within the acceptable range, the rear height control sensor initialization will end as an abnormal termination, and the warning light will blink 6 times at 2 Hz continuously. Disconnect SST from the DLC3 and turn the ignition switch off. Then restart from "Check Warning Light".

   • If initialization cannot be finished normally, check the LVL terminal circuit (Click here), or perform inspections and repairs according to "Problem Symptoms Table" (Click here).

AUTO LEVELING SYSTEM INITIALIZATION (for TFT Display Type)

1. HEADLIGHT LEVELING ECU ASSEMBLY VEHICLE INFORMATION REGISTRATION (for TFT Display Type)

1. Turn the ignition switch to ON and check that "Headlight System Malfunction Visit Your Dealer" warning message is displayed on the multi-information display.

2. Using the headlight dimmer switch, turn the low beam headlights on and off 8 times within 20 seconds after turning the ignition switch to ON.

   Note:

   If the low beam headlights illuminate when the ignition switch to ON, shine a light on the automatic light control sensor to turn the low beam headlights off before operating the headlight dimmer switch.

   Tip:

   If this step cannot be completed within 20 seconds, turn the ignition switch off. Then, turn the ignition switch to ON and restart the procedure.

3. Check that the "Headlight System Malfunction Visit Your Dealer" warning message on the multi-information display continuously blinks 6 times at 2 Hz.

   Tip:

   • If the "Headlight System Malfunction Visit Your Dealer" warning message on the multi-information display does not start blinking after performing step (b), perform the procedure again.

   • If the "Headlight System Malfunction Visit Your Dealer" warning message on the multi-information display changes from blinking to illuminated, turn the ignition switch off and then to ON. If the "Headlight System Malfunction Visit Your Dealer" warning message is displayed 5 seconds or more after the ignition switch was turned to ON, the rear height control sensor sub-assembly LH may be malfunctioning.

4. Turn the ignition switch off.

2. HEADLIGHT LEVELING ECU ASSEMBLY INITIALIZATION (for TFT Display Type)

1. Check the vehicle condition.

   1. Put the vehicle in the following condition:

      • Vehicle is unloaded (except spare tire and spare tire tools, etc.).

      • No occupants other than the driver are in the vehicle.

      • Headlights are turned off.

      • Vehicle is stopped and vehicle height remains constant (vehicle is on a level surface and stable).

      Tip:

      When the above conditions are not met, initialization cannot be performed normally.

2. Check the "Headlight System Malfunction Visit Your Dealer" warning message on the multi-information display.

   1. Turn the ignition switch to ON, and check the condition of the "Headlight System Malfunction Visit Your Dealer" warning message on the multi-information display.

      OK

      Condition	Specified Condition
      Headlight leveling ECU assembly vehicle information registration has been completed or there is an initialization malfunction	"Headlight System Malfunction Visit Your Dealer" blinks 6 times at 2 Hz.
      Removal/installation or replacement of the rear height control sensor sub-assembly LH, replacement of the suspension, etc.	"Headlight System Malfunction Visit Your Dealer" is not displayed on the multi-information display.

      Tip:

      If the condition of the headlight beam level control system warning light in the combination meter assembly is not as specified, check the wire harness(es) and connector(s) of the headlight leveling ECU assembly.
