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
ET085 Hazard warning lights button
ET111 Front fog lights request
ET082 Rear fog lights request
ET083 Left hand indicator request
ET084 Right hand indicator request
ET463 Door(s) or tailgate

Check for + 12 V (when there is a main beam headlights request) on connection RPD of component 226 and
connection RPG on component 227. Check for an earth on connection MAR of component 226 and on
connection MAS of component 227.
Main beam headlights check:
Check the insulation, continuity and the absence of interference resistance on the following connections:
Front right-hand main beam headlight:
●Connection code RPD between components 226 and 1016.
●Connection code MAR between component 226 and earth MAR.
Front left-hand main beam headlight:
●Connection code RPG between components 227 and 1016.
●Connection code MAS between component 227 and earth MAS.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check for + 12 V on connections BP59 and BP11 of component 209. Check for earth on connection MAN (for
right-hand drive vehicles) or MAM (for left-hand drive vehicles) of component 209.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check between the horn and lights switch and the passenger compartment fuse and relay box:
Check the insulation, continuity and the absence of interference resistance on the following connections:
●Connection code R between components 209 and 1016.
●Connection code BP59 between components 209 and 1016.
●Connection code BP11 between components 209 and 1016.
●Connection code MAN or MAM between components 209 and earth MAN or earth MAM (depending on the
driving layout, right- or left hand drive).
Check between the engine relay/fuse box (component 597) and the Passenger compartment fuse and relay
box (component 1016):
●Connection code BP11 between components 597 and 1016.
●Connection code BP13 between components 597 and 1016.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the supplies, earth and connections are correct, replace the horn and lights switch.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a complete check with the diagnostic tool.

ALP 11 No See-me-home lighting
NOTESOnly check this customer complaint after performing a complete check with the
diagnostic tool.
Check whether the vehicle has a rain/light sensor. If the vehicle does not have a rain/light sensor, explain to the
customer that this is normal, and that the vehicle does not have this feature.
Check that LC025 "See-me-home lighting" is "With", otherwise use CF032 "See-me-home lighting".
Check that the ignition is switched off.
Flash the headlights one or more times (as required) to activate the See-me-home lighting function.
Check that the horn and lights switch is operating correctly using status ET081 "Lighting stalk position". In the
event of a fault with the horn and lights switch, refer to the interpretation of status ET081 "Lighting stalk
position".
Use the following commands to check that the side lights, dipped headlights and main beam headlights are
operating correctly.
–AC055 "Side lights",
–AC054 "Dipped headlights",
–AC062 "Main beam headlights".
In the event of a fault, refer to the interpretation of the following faults:
–DF087 "Side lights relay control circuit",
–DF088 "Dipped headlights relay control circuit",
–DF098 "Main beam headlights relay control circuit".
If the fault is still present, contact Techline.
AFTER REPAIRCarry out a complete check with the diagnostic tool.
