AUTO LEVELING SYSTEM INITIALIZATION

id091800805800

Caution
•  Perform with the vehicle in an unloaded condition (no occupants; spare tire, jack and tools are in designated positions.)

With AFS (Adaptive front lighting system)


Without M-MDS

Note
•  If the following servicing is to be done, perform the procedure for the case where system initialization has never been done. (See Initialization has never been performed.)
―  AFS control module is newly replaced.
•  If the following servicing is done, perform the procedure for the case where the system is reset after initialization has already been completed. (See Initialization operation implemented and resetting to be performed.)
―  Auto leveling sensor is removed/installed.
―  Auto leveling sensor is replaced.
―  Procedure for changing vehicle height is performed such as changing suspension.
―  Initialized AFS control module is installed


Initialization has never been performed

Caution
•  Perform the procedures in Steps 2 to 5 within 30 s.

1.  Switch the ignition to off.

2.  Set a jumper wire to the DLC-2 B terminal.

3.  Switch the ignition to ON.

4.  Verify that the AFS OFF light flashes every 0.5 s.

am6zzw00006144

5.  Ground the DLC-2 B terminal 3 times or more at 1 s intervals using the jumper wire.

6.  After the AFS OFF light flashes three times at 0.5 s intervals, verify that it turns off.

•  If the AFS OFF light continues to flash at 0.5 s intervals, perform a DTC inspection, as there could be a malfunction in the auto leveling system. (See DTC INSPECTION [AFS (ADAPTIVE FRONT LIGHTING SYSTEM)].) Repair or replace the malfunctioning area, then repeat the procedure from Step 1.

7.  Verify that the motor inside the headlight leveling actuator operates and the headlight optical axis lowers from its current position and returns to its original position.

•  If the motor inside the headlight leveling actuator does not operate, the headlight optical axis may be at the bottommost position, or the procedure may have been performed incorrectly. Therefore, park the vehicle on level ground and resume the procedure from Step 1.

8.  Disconnect the jumper wire from DLC-2.

9.  Verify that the AFS OFF light is not illuminated.


Initialization operation implemented and resetting to be performed

Caution
•  Perform the procedures in Steps 4 to 7 within 30 s.
•  Perform the procedures in Steps 6 to 7 within 5 s.

1.  Switch the ignition to off.

2.  Turn on the headlights TNS position.

3.  Set a jumper wire to the DLC-2 B terminal.

4.  Switch the ignition to ON.

5.  Verify that the AFS OFF light turns off after it illuminates for approx. 3 s.

7.  The light switch switches in the following order: TNS→ON→OFF→ON→OFF→ON→OFF

8.  After the AFS OFF light flashes three times at 0.5 s intervals, verify that it turns off.

•  If the AFS OFF light continues to flash at 0.5 s intervals, perform a DTC inspection, as there could be a malfunction in the auto leveling system. (See DTC INSPECTION [AFS (ADAPTIVE FRONT LIGHTING SYSTEM)].) Repair or replace the malfunctioning area, then repeat the procedure from Step 1.

9.  Verify that the motor inside the headlight leveling actuator operates and the headlight optical axis lowers from its current position and returns to its original position.

•  If the motor inside the headlight leveling actuator does not operate, the headlight optical axis may be at the bottommost position, or the procedure may have been performed incorrectly. Therefore, park the vehicle on level ground and resume the procedure from Step 1.

10.  Pull out the jumper wire from DLC-2.

11.  Verify that the AFS OFF light is not illuminated.


With M-MDS

Caution
•  Perform with the vehicle in an unloaded condition (no occupants; spare tire, jack and tools are in designated positions).

1.  Connect the M-MDS IDS) to the DLC-2.

2.  After the vehicle is identified, select "Electrical", then "Exterior Lighting", then “Headlamp“, then “Auto Leveling Sensor Re-zero Procedure“ from the initial screen of the IDS.

3.  Perform the procedure according to the directions on the screen.
