• Perform headlight auto leveling system initialization if any of the following services is performed.
-
― Auto leveling control module/AFS control module replacement
― Auto leveling sensor replacement or removal/installation
― Any service which changes vehicle height, such as suspension replacement or removal/installation
• Two different procedures are available for the headlight auto leveling system initialization; 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 spare tire, jack and vehicle tools.
2. Adjust the tire pressure to the specification. (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 headlight auto-leveling malfunction indicator light/AFS OFF indicator light continues flashing during the first initialization, however, continue the work because it does not indicate an improper procedure.
6. After vehicle identification, the following can be selected from the M-MDS initial screen.
- (1) "Electrical"
