Switch on the forced + after ignition feed:
–with the vehicle card in the card reader,
–press and hold the Start button (longer than 5 seconds) with start-up conditions not fulfilled,
–connect the diagnostic tool and perform the required operations.
Switching off the forced + after ignition feed:
Press the Start button twice briefly (less than 3 seconds).
Ensure that the + after ignition feed has been cut off by checking that the computer warning lights on the
instrument panel have gone out.

NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present after the multimedia system has been switched on using
the on/off button.
Use the wiring diagrams Technical Note for Scénic II ph2, Espace IV ph2, Trafic II
ph2 or Kangoo 2.
Check the battery voltage,
Check the charging circuit (see Technical Note 6014A, Checking the charging circuit).
Check the condition of the multimedia network interface unit supply fuse.
If the supply fuse is correct, check for + 12 V on connection BCP4 (Kangoo 2), BCP4 (Trafic II ph2), BP3A
(Espace IV ph2) or BCP3 (Scénic II ph2).
If there is no + 12 V, check the continuity of connection BCP4 (Kangoo 2), BCP4 (Trafic II ph2),
BP3A (Espace IV ph2) or BCP3 (Scénic II ph2).
Check for earth on connection MAN (Kangoo 2), MAN (Trafic II ph2 and Scénic II ph2),
NC (Espace IV ph2).
If the connection is 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 fuse is not correct, check the insulation against earth on connection BCP4 (Kangoo 2), BCP4 (Trafic II
ph2), BP3A (Espace IV ph2) or BCP3 (Scénic II ph2).
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Replace the fuse.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other possible faults.

NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present after:
–the + after ignition feed is activated,
–the multimedia system has been switched on using the on/off button.
Use the wiring diagrams Technical Note for Scénic II ph2, Espace IV ph2, Trafic II
ph2 or Kangoo 2.
Look for any damage to the wiring harness, check the condition and connection of the connectors on
components 261, 1714 and 1127.
Manipulate the wiring harness in order to observe a change in the fault status (present → stored).
If the connector(s) is faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, W iring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the insulation, continuity and the absence of interference resistance of the following connection:
–connection code 34HU between components 261, 1714 and 1127.
If the connection is 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 REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other possible faults.
