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

WARNING: This page is about a different car, the 2017 Mazda CX-9. However, it is still accessible from the selected car via links, so may be relevant.

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.
The AFS 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 AFS control module is replaced.

Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .)
Remove the front scuff plate (LH). (See FRONT SCUFF PLATE REMOVAL/INSTALLATION .)
Remove the front side trim (LH). (See FRONT SIDE TRIM REMOVAL/INSTALLATION .)
Disconnect the connector.
