Auto Leveling Control Module Removal/Installation

WARNING: This page is about a different car, the 2020 Mazda MX-5 Miata. However, it is still accessible from the selected car via links, so may be relevant.
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 from the auto leveling sensor 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.
