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 using 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 Without using M-MDS.)

―  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 has never been performed.)

―  Auto leveling sensor is removed/installed.

―  Auto leveling sensor is replaced.

―  Procedure for changing vehicle height is performed such as changing suspension.

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.

am3uuw00004333

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, the following malfunction can be considered. Repair or replace the malfunctioning area, then repeat the procedure from Step 1.

―  Auto leveling sensor malfunction (See AUTO LEVELING SENSOR INSPECTION.)

―  AFS control module malfunction

―  Instrument cluster malfunction (See INSTRUMENT CLUSTER INSPECTION.)

―  Malfunction in the related wiring harnesses

7.  Disconnect the jumper wire from DLC-2.

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

3.  Turn on the headlights TNS position.

4.  Switch the ignition to ON.

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

7.  The headlight 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, the following malfunction can be considered. Repair or replace the malfunctioning area, then repeat the procedure from Step 1.

―  Auto leveling sensor malfunction (See AUTO LEVELING SENSOR INSPECTION.)

―  Instrument cluster malfunction (See INSTRUMENT CLUSTER INSPECTION.)

―  AFS control module malfunction

―  Malfunction in the related wiring harnesses

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

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

Using 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 to the DLC-2.

2.  After the vehicle is identified, select the following items from the initial screen of the M-MDS.

•  When using the IDS (laptop PC)

1.  Select “Electrical”.

2.  Select “Exterior Lighting”.

3.  Select “Headlamp”.

4.  Select “Auto Leveling Sensor Re-zero Procedure”

•  When using the PDS (Pocket PC)

1.  Select the “All Tests and Calibrations”.
