Procedure (continued)

Espace IV Phase 2: To save energy, the UCH on the Espace IV Phase 2 cuts out the + after ignition feed after 3 minutes.To run fault finding on a computer, it is possible to force the + after ignition feed for 1 hour by applying the following procedure: Press the card unlocking button. Insert the card into the reader. Press the Start button (interrupting the timed + after ignition feed mode). Press and hold the Start button for over 5 seconds until the engine immobiliser warning light starts to flash rapidly

(4 Hz).

This forced + after ignition feed mode remains active for 1 hour.Pressing the Start button or removing the card from the card reader cuts off the + after ignition feed but does not cut off the forced after ignition feed timed mode. Until one hour has elapsed, activating the + after ignition feed will restart forced + after ignition feed for the remaining time.

Faults

Faults are displayed as present or stored (they appeared in a certain context and have since disappeared, or they are still present but cannot be diagnosed in the current context).

The present or stored status of faults should be considered when using the diagnostic tool after the + after ignition feed is switched on (without any action on the system components).

For a present fault, apply the procedure described in the Interpretation of faults section.For a stored fault, note the faults displayed and apply the instructions in the Notes section.

If the fault is confirmed when the instructions in the Notes section are applied, the fault is present. Deal with the fault.

If the fault is not confirmed, check: the electrical lines which correspond to the fault, the connectors on these lines (corrosion, bent pins, etc.), the resistance of the component detected as faulty, the condition of the wires (melted or split insulation, wear).

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.

Conformity check

The aim of the conformity check is to check data that does not produce a fault on the diagnostic tool when the data is inconsistent. Therefore, this stage is used to: carry out fault finding on faults that do not have a fault display, and which may correspond to a customer complaint. check that the system is operating correctly and that there is no risk of a fault recurring after repair.

This section gives the fault finding procedures for statuses and parameters and the conditions for checking them.

If a status is not behaving normally or a parameter is outside the permitted tolerance values, consult the corresponding fault finding page.

Customer complaints - Fault finding chart

If the test with the diagnostic tool is correct but the customer complaint is still present, the fault should be processed by customer complaints.

A summary of the overall procedure to follow is provided on the following page in the form of a flow chart

4. FAULT FINDING PROCEDURE (continued)

Wiring check

Fault finding problemsDisconnecting the connectors and/or manipulating the wiring 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 inspectionLook 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 inspectionWhile manipulating the wiring, 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 componentDisconnect 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 checkCheck the continuity of entire lines, then section by section.Look for a short circuit to earth, to +12 V or to another wire.

If a fault is detected, repair or replace the wiring harness.

5. FAULT FINDING LOG

You will always be asked for this log: when requesting technical assistance from the Techline, when requesting approval before replacing parts for which approval is compulsory, to be attached to monitored parts for which reimbursement is requested. The log is needed for warranty

reimbursement, and enables better analysis of the parts removed.

6. SAFETY INSTRUCTIONS

Safety rules must be observed during any work on a component to prevent any material damage or personal injury: check the battery voltage to avoid incorrect operation of computer functions, use the proper tools.

IMPORTANT!

IMPORTANTAll faults involving a complex system call for thorough diagnostics with the appropriate tools. The FAULT FINDING LOG, which should be completed during the fault finding procedure, ensures a record is kept of the procedure carried out. It is an essential document when consulting the manufacturer.

IT IS THEREFORE ESSENTIAL THAT THE FAULT FINDING LOG IS FILLED OUT EVERY TIME IT IS REQUESTED BY TECHLINE OR THE WARRANTY RETURNS DEPARTMENT.

NOTES



Try to establish dialogue with a computer on another vehicle to check that the diagnostic tool is not faulty. If the diagnostic tool is not causing the fault and dialogue cannot be established with any other computer on the same vehicle, it may be that a faulty computer is disrupting the fault finding line.Use a process of successive disconnections to locate this computer.Check the battery voltage, component code 107, and perform the necessary operations to obtain the correct voltage (12 V < X < 15 V).

Check the presence and condition of the computer supply fuses: for Espace IV Phase 2: F15 (30 A), for Scnic II Phase 2: SHUNT (2AA).Check the connection of the multimedia network interface unit connector, component code 1714 and the condition of its connections.If the connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.Check that the computer is correctly supplied by checking the following connections: BP3A between components 260 and 1714 (for Espace IV Phase 2), BCP3 between components 260 and 1714 (for Scnic II Phase 2), BPT between components 645 and 1714 (for Scnic II Phase 2), MAN between component 1714 and earth (for Scnic II Phase 2), NC between component 1714 and earth (for Espace IV Phase 2).If the connection(s) 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.
