11.DEF: Battery voltage too low
NOTESThe fault is declared present after the dipped headlights are switched on, or during
a road test.
C.O
NOTESPriority when dealing with a number of faults.
Run a fault finding procedure on the UCH (see 87B, Passenger compartment connection unit) or UPC
(for Scénic) (see 87G, Engine compartment connection unit) to check the correct operation of the stalk.
Check the condition of the contacts and make sure that the xenon bulb computer is properly connected.
Check the continuity and absence of interference resistance in the following connection:
For Scénic II:
Black 6-track connector for the Protection and switching unit connector
track 5
For Vel Satis/Espace or Laguna II:
Black, 6-track connector of the UCH track 3B2Track 6 of the xenon
bulb computer.
If the fault is still present after these checks, replace the dipped headlights control stalk.
