AUTO LEVELING SYSTEM INITIALIZATION
CAUTION:
- Perform with the vehicle in an unloaded condition (no occupants; spare tire, jack and tools are in designated positions.)
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.
- 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.
- 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.
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 Testing and Inspection
- AFS control module malfunction
- Instrument cluster malfunction Component Tests and General Diagnostics
- 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.
Without DRL or with DRL lamp bulb
- Switch the ignition to off.
- Set a jumper wire to the DLC-2 B terminal.
- Turn off the headlights.
- Switch the ignition to ON.
- Verify that the AFS OFF light flashes.
- Connect terminal B (INIT) of the DLC-2 to terminal J (GND) using a jumper wire.
- The headlight switch switches in the following order: OFF->ON->OFF->ON->OFF->ON->OFF
- 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 Testing and Inspection
- Instrument cluster malfunction Component Tests and General Diagnostics
- AFS control module malfunction
- Malfunction in the related wiring harnesses
- Pull out the jumper wire from DLC-2.
- Verify that the AFS OFF light is not illuminated.
Without DRL lamp bulb
- Switch the ignition to off.
- Set a jumper wire to the DLC-2 B terminal.
- Turn on the headlights TNS position.
- Switch the ignition to ON.
- Verify that the AFS OFF light flashes.
- Connect terminal B (INIT) of the DLC-2 to terminal J (GND) using a jumper wire.
- The headlight switch switches in the following order: TNS->ON->OFF->ON->OFF->ON->OFF
- 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.

- 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".
2 Select "Auto Leveling Sensor Re-zero Procedure".
3 Perform the procedure according to the directions on the screen.
