LIGHTING
Fault finding - Function80D
The LIGHTING function is divided into two sub-functions: Lighting command, Lighting power.
If the vehicle is equipped with a light detector, this function is controlled by the UCH.
Otherwise this function is controlled directly with no intervention from the UCH.
1. Lighting control
Operated by the driver
The UCH receives the driver's request via the steering column switches and the hazard warning lights button.
The UCH controls the supply to the side lights, dipped headlights, main beam headlights and front fog lights.
The dipped headlights are still supplied when the main beam headlights are activated.
Automatic headlighting: the automatic lighting function is activated by switching the side lights on and off twice in
succession: a beep will sound to confirm this.
Check the statuses of the following commands:
Operated by the light sensor
The rain and light sensor is a single and unique sensor fitted in the windscreen. It is linked by a single connection to
the UCH.
The light sensor enables automatic operation of the side lights and dipped headlights as soon as the vehicle is in a
dark place (tunnel, night, gloomy weather conditions, etc.).
View the sensor status using status ET115 Request to switch on lights by light sensor.
The sensor configuration can be viewed by reading configuration LC044 Rain/light sensor and can be altered using
command CF035 Rain/light sensor.
The automatic lighting function is configured using CF193 "Automatic lighting function" and can be viewed using
LC095 "Automatic lighting function". Configuration CF194 "Automatic wiper function" is also connected to the
automatic lighting function and this function can be viewed using LC096 "Automatic wiper function".
2. Lighting output
The UCH controls the interior lighting supply (courtesy lights, footwell lights, etc.), the air conditioning and central
locking indicator lights.
The UCH controls the supply to the rear lights, front lights and the indicators.
The operation of the lights supplied by the UCH can be checked using actuator commands AC009 "Rear fog
lights", AC022 "Left-hand indicator", AC023 "Right-hand indicator", AC063 "Gradual lighting and dimming
of the courtesy light", AC062 "Main beam headlights", AC054 "Dipped headlights", AC055 "Side lights" and
AC008 "Front fog lights". ET081 Lighting stalk position
