CAUTION / NOTICE / HINT
Note
The necessary procedures (adjustment, calibration, initialization or registration) that must be performed after parts are removed and installed, or replaced during No. 1 headlight ECU sub-assembly LH removal/installation are shown below.
| Performed Work or System Condition | Necessary Procedures | Proceed to |
|---|---|---|
| Replacement of the No. 1 headlight ECU sub-assembly LH | Synchronize the vehicle information | SYNCHRONIZE VEHICLE INFORMATION |
| Perform No. 1 headlight ECU sub-assembly LH initialization (w/o Air Suspension System) | No. 1 headlight ECU sub-assembly LH INITIALIZATION | |
| 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. have been performed (w/o Air Suspension System) | Perform No. 1 headlight ECU sub-assembly LH initialization | |
| Battery terminal is disconnected and connected | Steering sensor zero point calibration |
A new No. 1 headlight ECU sub-assembly LH cannot operate until vehicle information synchronization has been performed.
After replacing the No. 1 headlight ECU sub-assembly LH, it is necessary to perform vehicle information registration and initialization.
Even if the No. 1 headlight ECU sub-assembly RH is replaced with a new one, vehicle information synchronization is not necessary.
If the steering sensor zero point calibration is not performed, the cornering lights may not operate correctly.
PROCEDURE
SYNCHRONIZE VEHICLE INFORMATION
When using the GTS:
Turn the ignition switch off.
Connect the GTS to the DLC3.
Turn the ignition switch to ON and check that "HEADLIGHT SYSTEM MALFUNCTION VISIT YOUR DEALER" warning message is displayed on the multi-information display.
Enter the following menus: Body Electrical / AFS / Utility / ECU Information Sync.
Check the display on the GTS and press "Next".
Check that the "HEADLIGHT SYSTEM MALFUNCTION VISIT YOUR DEALER" warning message on the multi-information display continuously blinks 6 times at 2 Hz.
Press "Exit" and turn the ignition switch off.
Tech Tips
If the "HEADLIGHT SYSTEM MALFUNCTION VISIT YOUR DEALER" warning message on the multi-information display does not start blinking after performing step (iv), perform the procedure again.
If the "HEADLIGHT SYSTEM MALFUNCTION VISIT YOUR DEALER" warning message on the multi-information display changes from blinking to illuminated, the rear height control sensor sub-assembly LH may be malfunctioning.
When not using the GTS:
Turn the ignition switch to ON and check that "HEADLIGHT SYSTEM MALFUNCTION VISIT YOUR DEALER" warning message is displayed on the multi-information display.
Using the light control switch, turn the low beam headlights on and off 8 times within 20 seconds after turning the ignition switch to ON.
Note
Turn the low beam headlights on and off at intervals of less than 2 seconds.
Tech Tips
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.
Check that the "HEADLIGHT SYSTEM MALFUNCTION VISIT YOUR DEALER" warning message on the multi-information display continuously blinks 6 times at 2 Hz.
Tech Tips
If the "HEADLIGHT SYSTEM MALFUNCTION VISIT YOUR DEALER" warning message on the multi-information display does not start blinking after performing step (ii), 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 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.
Turn the ignition switch off.
Note
w/o Air Suspension System:After synchronizing the vehicle information, initialize the No. 1 headlight ECU sub-assembly LH.
NO. 1 HEADLIGHT ECU SUB-ASSEMBLY LH INITIALIZATION
Prepare vehicle for initialization
Unload the trunk and vehicle, ensuring that the spare tire, tools and jack are in their original positions.
Check that there are no occupants in the vehicle.
Turn off the headlights.
Stop the vehicle on a level surface and keep the vehicle height unchanged.
Check the "HEADLIGHT SYSTEM MALFUNCTION VISIT YOUR DEALER" on the multi-information display.
Turn the ignition switch to ON, and check the condition of the "HEADLIGHT SYSTEM MALFUNCTION VISIT YOUR DEALER" on the multi-information display.

*: The number of times that the "HEADLIGHT SYSTEM MALFUNCTION VISIT YOUR DEALER" on the multi-information display blink is determined by the "Position ID" selected.
If initialization does not finish normally, restart the initialization procedure from step (i).
If the "HEADLIGHT SYSTEM MALFUNCTION VISIT YOUR DEALER" warning message is displayed on the multi-information display, the No. 1 headlight ECU sub-assembly LH may be malfunctioning.
Check that initialization finishes normally and turn the ignition switch off.
Initialization (When not using the GTS)
Turn the ignition switch to ON.
| *A | for European Model |
| *B | except European Model |
Check the specified number of times to turn the low beam headlights on and off.
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 |
|---|---|
| Within A range | 1 |
| Within B range | 2 |
| Within C range | 3 |
| Within D range | 4 |
| Within E range | 5 |
