Fault finding - Introduction80D
Faults
Faults are declared as either present or stored (depending on whether they appeared in a certain context and have
disappeared since, or whether they remain present but have not been diagnosed within the current context).
The present or stored status of faults should be taken into consideration when the diagnostic tool is switched on
after the + after ignition feed (without any system components being active).
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).
Conformity check
The aim of the conformity check is to check data that does not produce a fault on the diagnostic tool because the
data is inconsistent. Therefore, this stage is used to:
–run diagnostics 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 repairs.
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 OK but the customer complaint is still present, the fault should be processed by
customer complaint.
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 problems
Disconnecting the connectors and/or manipulating 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.
Ensure 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 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,
–for approval requests when replacing parts for which approval is obligatory
–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 damage or injury:
–check the battery voltage to avoid incorrect operation of computer functions,
–Use the proper tools.
Procedure for disconnecting the battery:
–switch off the ignition,
–switch off all electrical consumers,
–wait at least 1 minute for the electronic systems to switch off,
–disconnect the battery, starting with the negative terminal. IMPORTANTIMPORTANT
Any fault on a complex system requires thorough fault finding with the appropriate tools. The
FAULT FINDING LOG, which should be completed during the procedure, enables you to keep
track of the procedure which is carried out. It is an essential document when consulting the
manufacturer.
IT IS THEREFORE MANDATORY TO FILL OUT A FAULT FINDING LOG EACH TIME FAULT FINDING IS
CARRIED OUT.

Fault finding - Role of components
Side lights:
–without automatic headlighting:
The side lights are switched on directly via the passenger compartment fuse box using the horn and
lights switch.
–with ALS: when the horn and lights switch is operated, the side lights relay is activated via the UCH
which in turn switches on the side lights via the passenger compartment fuse box.
Dipped headlights:
–without automatic headlighting: the dipped headlights are switched on directly via the passenger
compartment fuse box using the horn and lights switch.
–with ALS: when the horn and lights switch is operated, the dipped headlights relay is activated via the
UCH which in turn switches on the dipped headlights via the passenger compartment fuse box.
Main beam headlights:
–without ALS: the main beam headlights are switched on directly via the passenger compartment fuse
box using the horn and lights switch.
–with ALS: when the horn and lights switch is operated, the main beam headlights relay is activated via
the UCH which in turn switches on the main beam headlights via the passenger compartment fuse box.
Rear fog lights:
–without ALS: the rear fog lights are switched on directly via the passenger compartment fuse box using
the horn and lights switch.
–with ALS: when the horn and lights switch is operated, the rear fog lights relay is activated via the UCH
which switches on the rear fog lights.
Front fog lights:
–without ALS: the front fog relay is activated when the horn and lights switch is operated and the front fog
lights are switched on.
–with ALS: when the horn and lights switch is operated, the front fog lights relay is activated via the UCH
which switches on the front fog lights.
Hazard warning lights:
–the hazard warning lights are switched on using the door locking/warning switch via the UCH and the
passenger compartment fuse box.
