NOTESTo display this fault as present or stored, run the command
AC016 Electrical supply circuit test.
Use Wiring Diagrams Technical Note for Mégane II or
Scénic II.
Check the conformity of the fuse F5 (20A) for the Protection and Switching Unit.
Check the insulation, continuity and the absence of interference resistance on the following connections:
–8E between components 1337 and 177,
–8F between components 1337 and 176.
If the connection or connections are faulty and if 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".
Erase the faults from the computer memory, switch the + after ignition supply off and
back on again and run another check using the diagnostic tool.
