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

–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).

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.

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
