Initialization

LIGHTING (EXT): LIGHTING SYSTEM: INITIALIZATION

NOTICE:
* Initialize the AFS ECU (headlight swivel ECU assembly) when the AFS ECU (headlight swivel ECU assembly) is replaced.
* If the vehicle is not equipped with air suspension system, 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 such operations as removal and reinstallation or replacement of the rear height control sensor sub-assembly RH.
* If the vehicle is not equipped with air suspension system, adjust the headlight aim after initializing the AFS ECU (headlight swivel ECU assembly) (except LED Headlight).
* When a malfunction is detected in the automatic headlight beam level control system or AFS, height control sensor signal initialization is impossible. Perform troubleshooting before initialization.

1. CHECK VEHICLE CONDITION

(a) Check the vehicle condition.

Result:





B -- Go to step 7
A -- Continue to next step.

2. CHECK VEHICLE CONDITION

(a) Check the vehicle condition.

Result:





B -- Go to step 4
A -- Continue to next step.

3. SYNCHRONIZE VEHICLE INFORMATION

(a) When using the Techstream:

(1) Turn the power switch off.

(2) Connect the Techstream to the DLC3.

(3) 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: Main Body / AFS / Utility / ECU Information Sync / Next.

(5) Check what is displayed on the screen of the Techstream 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.

(b) When not using the Techstream:

(1) 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).

HINT
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.

NOTICE:
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.

NEXT -- Continue to next step.

4. PREPARE VEHICLE FOR INITIALIZATION

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

(b) Check that there are no passengers in the vehicle.

(c) Turn off the headlights.

(d) Stop the vehicle on a level surface and keep the vehicle height unchanged.

NEXT -- Continue to next step.

5. CHECK AFS OFF INDICATOR LIGHT

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

OK:





HINT
If the indicator light does not come on when turning the power switch on (IG), inspect and repair it according to Problem Symptoms Table Exterior Lighting System.

NG -- GO TO PROBLEM SYMPTOMS TABLE
OK -- Continue to next step.

6. INITIALIZATION

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





SST : 09843-18040

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





HINT
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.





NOTICE:
* Turn the low beam headlights on and off at less than 3-second intervals.
* Be sure to operate the light control switch from outside the vehicle.

(b) Check the indicator light.

OK:





HINT
* *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 cannot be finished normally, disconnect SST from the DLC3 and turn the power switch off. Then, restart from procedure 1.

NG -- GO TO PROBLEM SYMPTOMS TABLE

OK -- TURN POWER SWITCH OFF (END)

7. SYNCHRONIZE VEHICLE INFORMATION

HINT
If the AFS ECU (headlight swivel ECU assembly) is replaced with a new one, synchronize the vehicle information.

(a) When using the Techstream:

(1) Turn the power switch off.

(2) Connect the Techstream to the DLC3.

(3) 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: Main Body / AFS / Utility / ECU Information Sync / Next.

(5) Check what is displayed on the screen of the Techstream and press "Next".

(6) Press "Exit" and turn the power switch off.

(b) When not using the Techstream:

(1) 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).

HINT
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.

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

(3) Turn the power switch off.
