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.
