HEADLIGHT LEVELING ECU ASSEMBLY INITIALIZATION (USING GTS) |
- HINT:
- Initialization for the headlight leveling ECU assembly is performed based on the fuel level, which is divided into 5 levels, indicated by the needle of the fuel receiver gauge.
Check the vehicle condition.
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).
- HINT:
- If the above conditions are not met, initialization cannot be performed normally.
- Vehicle is unloaded (except spare tire and spare tire tools, etc.).
Check that the warning message "Headlight System Malfunction Visit Your Dealer" is displayed on the combination meter assembly.
Check the warning message on the combination meter assembly 6 seconds after turning the ignition switch to ON.
- Standard:
Condition Specified Condition Headlight leveling ECU assembly initialization malfunction Warning flashes 6 times at 2 Hz continuously Removal/installation or replacement of the rear height control sensor sub-assembly, replacement of the suspension, etc. Warning message is not illuminated
- HINT:
- If the warning message condition is not as specified, check the wire harness(es) and connector(s) of the headlight leveling ECU assembly.
Initialization procedure
Turn the ignition switch to ON.
Enter the following menus: Body Electrical / HL AutoLeveling / Utility / Height Sensor Initialization.
Check what is displayed on the screen of the GTS and press "Next".
The appropriate position ID is determined by the fuel level (remaining amount of fuel) of the fuel receiver gauge as shown in the chart below.

- Standard:
Condition Specified Condition Headlight leveling ECU assembly initialization malfunction Warning flashes 6 times at 2 Hz → Warning flashes N* times at 2 Hz continuously (initialization completes normally) Removal/installation or replacement of the rear height control sensor sub-assembly, replacement of the suspension, etc. Off → Warning flashes N* times at 2 Hz continuously (initialization completes normally)
- HINT:
- *: Refer to the chart above for N.
- If the warning message condition on the combination meter assembly does not change, perform the procedure from the beginning once again.
- If the warning message illuminates continuously, there may be a malfunction in the headlight leveling ECU assembly.
Check that initialization has completed normally, and then turn the ignition switch off.
