Auto Leveling Control Module Removal/Installation

WARNING: This page is about a different car, the 2017 Mazda CX-5. 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 attitude angle while it is unoccupied.
The new auto leveling control module does not record the vehicle attitude angle while it is unoccupied.
The auto leveling control module reads the vehicle attitude angle information and records the vehicle attitude angle while it is unoccupied when the headlight auto leveling system initial setting is performed after the auto leveling control module is replaced.
Even if the battery is disconnected, the unoccupied vehicle attitude angle recorded by the auto leveling control module is not erased.

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 connectors and set the wiring harnesses aside to the positions where the auto leveling control module can be removed.
