Adaptive Front Lighting System (AFS) Control Module Removal/Installation

NOTE:
  • The AFS control module stores the vehicle specification information.
  • A new AFS control module does not store any vehicle specification information.
  • When the ignition is switched ON after the AFS control module is replaced, the AFS control module reads the vehicle specification information sent via CAN transmission from the instrument cluster, and stores the vehicle specification information.
  • The AFS control module records the vehicle height while it is unoccupied.
  • Even if the battery is disconnected, the unoccupied vehicle height recorded by the AFS control module is not erased.
  • The new AFS control module does not record the vehicle height while it is unoccupied.
  • When the headlight auto leveling system initialization is performed after the AFS control module is replaced, the AFS control module inputs the vehicle height from the auto leveling sensor and records the vehicle height in unloaded condition.
