DESCRIPTION

The headlight ECU sub-assembly LH sends automatic headlight beam level control signals to each headlight swivel and leveling motor via LIN communication.

Each headlight ECU sub-assembly and headlight swivel and leveling motor communicate via LIN communication.

The headlight swivel and leveling motor operates according to power supplied and automatic headlight beam level control signals from its respective headlight ECU sub-assembly and sends its operating state to the headlight ECU sub-assembly.

The headlight ECU sub-assembly LH stores a DTC if it detects that a headlight swivel and leveling motor is malfunctioning.
