ET047 Undetermined with the pedal depressed.
Check the condition and connection of the brake pedal switch connector.
If the connector is faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector; otherwise, replace the wiring.
With the brake pedal switch disconnected:
Check for + 12 V on component 160 on connection SP17.
If not correct:
–Check the condition and connection of fuse 1H in the passenger compartment relay and fuse box.
–Check the condition and the connection of the passenger compartment fuse and relay box connector. If the
connector is faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector; otherwise, replace the wiring.
–Check the insulation and continuity of connection SP17 between components 160 and 260. If the connection
is 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 it is still faulty, contact Techline.
With the brake pedal switch disconnected:
Check the continuity of the following connections:
●Connection code 65A,
●Connection code SP17 of component 160 (brake pedal switch piston free).
Only replace the brake pedal switch if it is not correct.
Check the condition and connection of the UCH connector PE2.
If the connector is faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector; otherwise, replace the wiring.
With the UCH and brake pedal switch disconnected:
Check the insulation and continuity of the following connection:
●Connection code 65A between components 645 and 160.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
The line is shared with the ABS computer or the ESP relay (depending on equipment) and the brake lights. In the
event of faulty insulation, it is therefore necessary, using a wiring diagram, to check the connections between the
brake pedal switch connector and these components.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.

ET085
HAZARD WARNING LIGHTS BUTTON
NOTESNo faults should be present or stored.
Use Wiring Diagrams Technical Note for MEGANE II or SCENIC II.
ET085 is Absent with button pressed.
Check the F16 15A fuse of the passenger compartment fuse and relay box on the left-hand side of the centre
console.
Replace it if necessary.
Check the door/warning switch connector (e.g.: connector properly connected, tabs bent, broken, oxidised).
If the connector is faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector; otherwise, replace the wiring.
Check the PE2 and PE1 connectors (e.g. connector properly connected, tabs bent, broken, oxidised).
If the connector is faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector; otherwise, replace the wiring.
Check for + 12 V on connection LPG of component 1391.
If the connector is faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector; otherwise, replace the wiring.
Check the insulation and continuity of the following connections:
●Connection code 64F.
●Connection code 64Q between components 645 and 1391.
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 following connections on component 1391 (button pressed):
●Connection code 64F.
●Connection code 64Q.
If there is insulation, replace the button.
If there is continuity, contact the techline.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.

ALP39 Accessories feed not activated
NOTESCheck the voltage of the battery.
Start the fault finding procedure with the ignition off and the vehicle locked.
When the vehicle is unlocked, the instrument panel should light up for a moment.
If not, carry out fault finding on the multiplex network and instrument panel.
Use Wiring Diagrams Technical Note for MEGANE II or SCENIC II.
The vehicle should switch to timed power (approximately 20 minutes) after the driver's door is opened (ET053
Driver's door).
If the timed supply is not triggered, try by:
–pressing the Start button (ET070 Start button), or
–turning on the hazard warning lights (ET085 "Hazard warning lights button"), or
–switching on the side lights (ET081 Lighting switch position).
If correct, run status fault finding for the faulty component.
If not correct, apply ALP No dialogue with the UCH.
The vehicle goes into accessories feed mode when the Start button is pressed (timed power active).
If it does not conform, check the operation of the Start button using status ET070 Start button and apply the fault
finding procedure associated with this status if necessary.
If the Start button operates correctly, use the fault finding procedure for status ET075 + accessories feed present.
Run fault finding and check the condition of the connectors of the + battery housing (Power fuses), of the power
board (maxi fuses), of the Protection and Switching Unit (UPC), of the Passenger Compartment Fuse and
Relay Box, of the Passenger Compartment Fuse and Relay Box option, and of the relay boards.
Check the condition and connection of the connectors on the UCH and the connectors on the UPC.
Check for + 12 V on connections BTP and 13AC of component 645.
Check for earth on connections 13E and NAM of component 645.
If one of the connectors is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring
repair, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a complete check with the diagnostic tool.
