5.4.1. Overview

The Exterior Lighting Manager (ExtrLiMgr) is a software component responsible for managing the exterior lighting system of a vehicle. It controls various lighting functions such as headlights, turn signals, brake lights, and other exterior lighting sources.

5.4.2. Functions

	Title	Description
1	Headlights Control	Controls low beam and high beam headlights based on user input from stalk switch and auto low beam request from light sensor. Implements high beam flash functionality.
2	Position Lights Control	Controls front and rear position lights based on user input and lock/unlock events from central locking. Implements welcome/goodbye light effects.
3	Daytime Running Lights Control	Controls daytime running lights (DRL) based on vehicle state and user input. DRL can be automatically activated in certain vehicle states.
4	Rear Fog Lights Control	Controls rear fog lights based on user input and vehicle state. Rear fogs can only be activated if low beams or position lights are on.
5	Turn Indicators Arbitration	Arbitrates between turn indicator requests and DRL/position light requests. Indicators have priority and can override DRL/position lights.
6	Lamp Fault Detection	Detects faults of the individual lamps by monitoring their status feedback signals. Activates corresponding DTCs if faults are detected.
7	Ready To Sleep Management	Manages the Ready To Sleep signal of the component to indicate its readiness to enter low power mode, considering the activity of exterior lights.
