id091800805500

Note

•  The auto leveling control module stores the vehicle specification information.

•  A new auto leveling control module does not store any vehicle specification information.

•  When the ignition is switched ON after the auto leveling control module is replaced, the auto leveling control module reads the vehicle specification information sent via CAN transmission from the instrument cluster, and stores the vehicle specification information.

•  The auto leveling control module records the vehicle height while it is unoccupied.

•  Even if the battery is disconnected, the unoccupied vehicle height recorded by the auto leveling control module is not erased.

•  The new auto leveling control module does not record the vehicle height while it is unoccupied.

•  The auto leveling control module reads the vehicle height information and records the vehicle height while it is unoccupied when the headlight auto leveling system initial setting is performed after the auto leveling control module is replaced.
