1.DEF: Voltage outside permitted range of values
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after several starting attempts, or with the engine
running.
Special notes:
Computer operating voltage: 9 V < PR071 < 16 V.
Battery voltage that is too low can cause the level 1 fault warning light to come on
thereby causing other faults to appear.
Use bornier Elé.1681 or Elé.1590 for any operation on the injection computer
connectors.
Check the continuity and absence of interference resistance of the following connections:
– connection code AP15 between components 120 and 1337 (Scénic II et Mégane II).
– connection code AP29 between components 120 and 597 (Laguna II).
If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the condition of the injection control unit supply relay (50A) located on a relay plate in the engine
compartment connection unit (no false contact or oxidation on the relay mounting clips).
Repair if necessary.
If the fault does not reappear, start the engine and wait 1 minute.
Carry out a road test and check the system faults.
If there are no faults, fault finding is complete.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
