Check the insulation, continuity and the absence of interference resistance on the following connections:
●Connection code 8A between components 231 and 209.
●Connection code BP16 between components 231 and 1016.
●Connection code MAM between components 231 and earth MAM.
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 the insulation, continuity and the absence of interference resistance on the following connections:
●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, the earth and the connections are correct, replace the horn and lights switch.
If the fault is still present, contact the Techline.

NOTESOnly check this customer complaint after performing a complete check with the
diagnostic tool.
Check, as a priority, the operation of status ET115 "Request to switch on the lights
via the light sensor" and commands AC054 Dipped headlights and AC055 Side
lights in the UCH.
Note:
For the lights to switch off automatically after driving, the following conditions must all be met:
–engine stopped,
–ignition: 0 (inactive),
–vehicle speed > 0 mph (0 km/h),
–driver's door: closed.
Carry out a multiplex network test. If the multiplex
network contains faults (see 88B, Multiplexing).
Check the operation of status ET142 "Engine
operating phase".
Is the status functioning correctly?
YES
Make sure that status ET239 Ignition switch
position is working.
Is the status functioning correctly?
YES
NOApply the procedure for processing status
ET142.

ALP 10 Lights not switching on at night
NOTESOnly check this customer complaint after performing a complete check with the
diagnostic tool.
The engine must be running in order for the automatic lighting function to operate and
the system must be equipped with a rain/light sensor.
Check, as a priority, the operation of status ET115 "Request to switch on the lights
via the light sensor" in the UCH. Check that the following faults are not present:
–DF011 "Rain/light sensor circuit",
–DF135 "Rain sensor",
–DF136 "Light sensor".
Deal with the above faults if they are present.
Note:
The sensor requests the lights to be switched on when there is poor light intensity (at night, in a tunnel, etc.).
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.
Activate the automatic lighting function by switching
the side lights on and off twice in succession:
a beep will sound to confirm this.
Did a beep sound?
YES
NORefer to the interpretation of status ET081
"Lighting stalk position".
