AUTO LEVELING SYSTEM INITIALIZATION

id091800805800

Without using M-MDS

Caution

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

• Perform the procedures in Steps 1 to 4 within 30 s.

1. Switch the ignition to ON.

• If the headlight auto leveling warning light illuminates after 10 s or more have elapsed since the ignition switch was turned to the ON position, perform a DTC inspection, as it is possible that there is a malfunction with the auto leveling system. (See DTC INSPECTION [INSTRUMENT CLUSTER].) Repair or replace for the malfunction, then repeat the procedure from Step 1.

Note

• If the auto leveling control module has never been initialized, the headlight auto leveling warning light flashes 2 times at 1.25 s intervals. However, this does not indicate a procedural mistake, and continue with the procedure as it is.

2. Turn on the headlights.

3. Connect terminal B (INIT) of the DLC-2 to terminal J (GND) using a jumper wire.

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.

4. The headlight auto leveling warning light flashes 3 times at 1.25 s intervals, and then turns off. Also, verify that the headlight optical axis lowers from its current position and returns to its original position.

Caution

• If the headlight auto leveling warning light does not flash 3 times at 1.25 s intervals or the headlight optical axis does not move, perform a DTC inspection, as there could be a malfunction in the auto leveling system. (See DTC INSPECTION [INSTRUMENT CLUSTER].) Repair or replace the malfunctioning area, then repeat the procedure from Step 1.

5. Disconnect the jumper wire from DLC-2.

6. Verify that the auto leveling system warning light turns off according to the table below.
