Procedure
To run fault finding on the vehicle's computers, switch on the ignition in fault finding mode (forced + after ignition
feed).
Proceed as follows:
–vehicle card in reader,

–connect the diagnostic tool and perform the required operations.
To cut off the + after ignition feed, proceed as follows:
–disconnect the diagnostic tool,
–press the Start button twice briefly (less than 3 seconds),
–check that the computer warning lights on the instrument panel have gone out to confirm that the + after ignition
feed has been cut off. Vehicle: Scenic II ph2

4. FAULT FINDING PROCEDURE (continued)
Wiring check
Fault finding problems
Disconnecting the connectors and/or handling the wiring harness may temporarily remove, the cause of a fault.
Electrical measurements of voltage, resistance and insulation are generally correct, especially if the fault is not
present when the analysis is made (stored fault).
Visual inspection
Look for damage under the bonnet and in the passenger compartment.
Carefully check the fuses, insulators and wiring harness routing.
Look for signs of oxidation.
Physical inspection
While manipulating the wiring harness, use the diagnostic tool to note any change in fault status from stored to
present.
Make sure that the connectors are properly locked.
Apply light pressure to the connectors.
Twist the wiring harness.
If there is a change in status, try to locate the source of the fault.
Inspection of each component
Disconnect the connectors and check the appearance of the clips and tabs, as well as the crimping (no crimping on
the insulating section).
Make sure that the clips and tabs are properly locked in the sockets.
Check that no clips or tabs have been dislodged during connection.
Check the clip contact pressure using an appropriate model of tab.
Resistance check
Check the continuity of entire lines, then section by section.
Look for a short circuit to earth, to + 12 V or with another wire.
If a fault is detected, repair or replace the wiring harness.

STORED FAULT
Clear the fault, switch off the ignition and disconnect the 20A computer supply fuse.
–Refit the fuse and switch the ignition back on.
–Turn on the navigation system.
If the fault reappears as stored, contact Techline.
If the fault does not reappear: operate the navigation system, including the CD multi-changer, the tuner-amplifier
and the hands-free telephone integrated control (if present on the vehicle) to check that the system is operating
correctly.
Check the conformity of the + 12 V on the BCP3 connection of the navigation computer 40-track connector
(component code 662).
Check that the earth on the MX connection of the 40-track connector of component 662 is perfect.
If any connection is faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring; otherwise, replace the wiring.
FAULT PRESENT
If the fault is present, contact the Techline.
AFTER REPAIRIf the computer was replaced (at the request of the Techline), reconfigure the computer
(see Configurations and programming).
Deal with any other faults.
