id091800812200

Note

•  The auto leveling control module/adaptive front lighting system (AFS) 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 front lighting system (AFS) 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

Caution

•  Perform Steps 5 and 6 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.)

3.  Move the vehicle to level ground.

4.  Connect the M-MDS to the DLC-2.

5.  Switch the ignition ON (engine 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.

6.  After vehicle identification is completed, select the following from the M-MDS initial screen.

(1)  Electrical components

(2)  Exterior lighting

(3)  Headlights

(4)  Auto leveling sensor

(5)  Auto leveling sensor initialization

7.  Verify the LED headlight warning light.

•  The initial setting is completed if the LED headlight warning light flashes 3 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 5.

•  If the LED headlight warning light turns on, the headlight auto leveling system may have a malfunction. Perform DTC inspection. (See DTC INSPECTION [AUTO LEVELING CONTROL MODULE].)(See DTC INSPECTION [ADAPTIVE FRONT LIGHTING SYSTEM (AFS) CONTROL MODULE].)(See DTC INSPECTION [ADAPTIVE LED HEADLIGHTS CONTROL MODULE].)

8.  Adjust the headlight aiming. (See HEADLIGHT AIMING.)

Procedure Not Using M-MDS

Caution

•  Perform Steps 4 and 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.)

3.  Move the vehicle to level ground.

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

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) 3 times at 0.5—1.5 s intervals as shown in the figure.
