HEADLIGHT AUTO LEVELING SYSTEM INITIALIZATION [(E)]

id0918008122x2

Note

•  The auto leveling control module/adaptive front lighting system (AFS) control module/adaptive LED headlights control module records the vehicle height in unoccupied condition by performing the headlight auto leveling system initialization.

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

―  Auto leveling control module/adaptive front lighting system (AFS) control module/adaptive LED headlights control module replacement

―  Any service which changes vehicle height, such as suspension replacement or removal/installation

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

Procedure Using M-MDS

1.  Empty the vehicle except for the spare tire, jack and vehicle tools.

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

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

4.  Move the vehicle to level ground.

5.  Connect the M-MDS.

6.  Switch the ignition ON (engine 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 ignition OFF and press [Next].

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

Procedure Not Using M-MDS

Caution

•  Perform Steps 4 and 5 within 30 s.

1.  Empty the vehicle except for the spare tire, jack and vehicle tools.

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

3.  Move the vehicle to level ground.

4.  Switch the ignition ON (engine off or on).

Note

•  The LED headlight warning light continues flashing during the first initialization, 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 a jumper wire, connect DLC-2 terminals B and J (ground) three times at 0.5—1.5 s intervals as shown in the figure.

6.  Verify the LED headlight warning light.

•  The initialization is completed if the LED headlight warning light flashes three times every 0.25 s and turns off. Go to the next step.

•  If the LED headlight warning light flashes at 0.25 s intervals, the procedure may have been performed incorrectly. Repeat the procedure from Step 4.

•  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.  Adjust the headlight aiming. (See HEADLIGHT AIMING [(E)].)
