Adaptive Front Lighting System (AFS) Control Module/Auto Leveling Control Module/Turn Light Unit Removal/Installation

NOTE:

The adaptive front lighting system (AFS) control module/auto leveling control module/turn light unit stores the vehicle specification information.
A new adaptive front lighting system (AFS) control module/auto leveling control module/turn light unit does not store any vehicle specification information.
When the ignition is switched ON after the adaptive front lighting system (AFS) control module/auto leveling control module/turn light unit is replaced, the adaptive front lighting system (AFS) control module/auto leveling control module/turn light unit reads the vehicle specification information sent via CAN transmission from the instrument cluster, and stores the vehicle specification information.
The adaptive front lighting system (AFS) control module/auto leveling control module/turn light unit records the vehicle attitude angle while it is unoccupied.
The new adaptive front lighting system (AFS) control module/auto leveling control module/turn light unit does not record the vehicle attitude angle while it is unoccupied.
The adaptive front lighting system (AFS) control module/auto leveling control module/turn light unit 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 adaptive front lighting system (AFS) control module/auto leveling control module/turn light unit is replaced.
Even if the battery is disconnected, the unoccupied vehicle attitude angle recorded by the adaptive front lighting system (AFS) control module/auto leveling control module/turn light unit 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 adaptive front lighting system (AFS) control module/auto leveling control module/turn light unit can be removed.

Disconnect the connector and remove the adaptive front lighting system (AFS) control module/auto leveling control module/turn light unit.
Install in the reverse order of removal.
Perform the adaptive front lighting system (AFS) control module/auto leveling control module/turn light unit automatic configuration using the following procedure.
1. Switch the ignition ON (engine off or on) and wait for 1 min or more.
2. Switch the ignition off and wait for 3 s or more.
3. Switch the ignition ON (engine off or on) and complete the adaptive front lighting system (AFS) control module/auto leveling control module/turn light unit automatic configuration.
Using the M-MDS, verify that DTCs U2300:54, U2300:55, or U2300:56 is not displayed.
- If DTC U2300:54, U2300:55, or U2300:56 is displayed, go to the DTC troubleshooting procedure. (See DTC U2300:54 [AFS/ALM] .) (See DTC U2300:55 [AFS/ALM] .) (See DTC U2300:56 [AFS/ALM] .)
If the adaptive front lighting system (AFS) control module/auto leveling control module/turn light unit is replaced with a new one, perform the headlight auto leveling system initialization. (See HEADLIGHT AUTO LEVELING SYSTEM INITIALIZATION .)
