HEADLIGHT AUTO LEVELING SYSTEM INITIALIZATION

id091800702400

Note

•  The auto leveling control module/adaptive LED headlight control module stores the vehicle attitude angle by performing the headlight auto leveling system initial setting.

•  Perform headlight auto leveling system initial setting if any of the following services is performed.

―  Auto leveling control module/adaptive LED headlight control module replacement

―  Any servicing which changes the vehicle attitude angle is performed, such as suspension replacement, removal, or installation

•  Two different procedures are available for the headlight auto leveling system initial setting; one which uses the M-MDS, and one which does not.

Procedure Using M-MDS

1.  Empty the vehicle except for the jack and vehicle tools.

2.  Inspect the wheel alignment. (See WHEEL ALIGNMENT PRE-INSPECTION.) (See FRONT WHEEL ALIGNMENT.) (See REAR WHEEL ALIGNMENT.)

3.  Adjust the tire pressure to the standard.(See WHEEL AND TIRE SPECIFICATION [(E)].)

4.  Move the vehicle to level ground.

5.  Connect the M-MDS to the DLC-2.

6.  Switch the main power ON (READY off or on).

7.  Activate the M-MDS and perform the following procedure.

(1)  Press [Start] to start the vehicle identification.

(2)  Press the [Toolbox] tab.

(3)  Press the [Work Support] icon.

(4)  Press [LIGHTING SYSTEMS].

(5)  Press [Run] for [Calibrating Headlight Leveling Sensor].

(6)  Confirm the Calibrating Headlight Leveling Sensor procedure from Step (7) to Step (10), and press [Next].

(7)  Verify that the following conditions/operations are met/completed and then press [Next].

•  Wheel alignment and tire pressure are inspected

•  Vehicle is moved to level ground

•  Vehicle is not shaken up/down, left/right

•  Worker is out of vehicle

(8)  When the M-MDS processing is completed, press [Next].

(9)  Press [Next] to complete [Calibrating Headlight Leveling Sensor].

(10)  Switch the main power OFF and press [Next].

8.  Perform the headlight aiming adjustment.(See HEADLIGHT AIMING [(E)].)

Procedure Not Using M-MDS

Caution

•  Perform Steps 4—5 within 30 s.

1.  Empty the vehicle except for the jack and vehicle tools.

2.  Adjust the tire pressure to the standard.(See WHEEL AND TIRE SPECIFICATION [(E)].)

3.  Move the vehicle to level ground.

4.  Switch the main power ON (READY off or on).

Note

•  The LED headlight warning light continues flashing during the first initial setting, however, continue the work because it does not indicate an improper procedure.

Caution

•  If the terminals are mistakenly connected, vehicle damage or fire could occur. When connecting with the jumper wire, thoroughly verify what terminals are being connected to prevent a miss-connection.

5.  Using jumper wires, connect terminal B and terminal J (GND) of DLC-2 three times at 0.5—1.5 s intervals as shown in the figure.

6.  Verify the LED headlight warning light.

•  If the LED headlight warning light flashes three times at 0.25 s intervals and turns off as shown in the figure, it indicates that the headlight auto leveling system initialization is complete. Go to the next step.

•  If the LED headlight warning light flashes at intervals of 0.25 s, the servicing may not have completed normally, so start over from Step 5.

•  If the LED headlight warning light turns on, the headlight auto leveling system may have a malfunction. Perform DTC inspection. (See DTC INSPECTION.)

―  Repair or replace the malfunctioning location, then repeat the procedure from Step 4.

7.  Perform the headlight aiming adjustment.(See HEADLIGHT AIMING [(E)].)
