B2424 Headlight Leveling Motor LH Communication Malfunction
B2425 Headlight Leveling Motor RH Communication Malfunction
B2440 Lost Communication with AHS EDU LH Module
B2441 Lost Communication with AHS EDU RH Module

DESCRIPTION

The headlight ECU sub-assembly sends auto leveling control signals to the headlight leveling motor via LIN communication.

The headlight leveling motor operates according to the power supply and control signals from the headlight ECU sub-assembly and sends its operation status to the headlight ECU sub-assembly via LIN communication.

The headlight ECU sub-assembly sends AHS control signals to the light control LED ECU via LIN communication.

The light control LED ECU receives power and control signals from the headlight ECU sub-assembly, controls the additional LEDs and additional fans, and sends its operation status to the headlight ECU sub-assembly via LIN communication.
