4FUNCTION: LIGHTING
4.1 Sub-function: LIGHTING CONTROL
The UCH receives the request from the driver, from the lighting stalk, from the hazard warning lights button and, if
fitted to the vehicle, from the light detector.
The UCH requests the Protection and Switching Unit, via the multiplex network, to provide power to the side lights,
dipped headlights, main beam headlights and fog lights (front).
If a request to activate the lighting is made, the UPC provides power to the xenon bulb computers.
The dipped headlights are still supplied when the main beam headlights are activated.
The following statuses can be displayed:
ET081 Lighting stalk position.
ET082 Rear fog lights request.
ET085 Hazard warning lights switch.
ET083 Left-hand direction indicator request.
ET084 Right-hand indicator request.
If the UCH cannot determine the position of the control stalk, or inform the Protection and Switching Unit of the
control stalk's position, the Protection and Switching Unit will activate the dipped headlights.
4.2 Sub-function: LIGHTING POWER
The UCH controls the power supply for the rear fog light (a single one), direction indicators and interior lighting (roof
lights and footwell/floor lights).
The interior lighting request can be displayed using the ET112 Interior lighting control status.
Operation of the lights powered by the UCH can be checked using the actuator commands AC009 Rear fog lights,
AC022 Left-hand direction indicator, AC023 Right-hand direction indicator, AC021 Interior lights and AC027
Footwell/floor lighting.
