Use Wiring Diagrams Technical Note for Mégane II or
Scénic II.
Check that the UPC fuse F21 (15A) is correct.
Check the insulation, continuity and the absence of interference resistance on the following connections:
–39A, between components 1337 and 219,
–39C, between components 1337 and 219.
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 fault is still present, contact the Techline.
AFTER REPAIRRun command AC016 Electrical supply circuits test.
Clear the computer fault memory, switch the + after ignition supply off and back on, and
run another check with the diagnostic tool.
