Faults
Faults are declared present or stored (depending on whether they appeared in a certain context and have
disappeared since, or whether they remain present but are not diagnosed within the current context).
The present or stored status of faults should be taken into consideration when the diagnostic tool is switched on
following + after ignition feed being activated (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 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 for these lines (for oxidation, 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 the statuses and parameters that do not produce a fault display on the
diagnostic tool when they are 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 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 treated 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 problems
Disconnecting the connectors and/or manipulating the wiring may temporarily remove the cause of a fault.
Electrical measurements of the voltage, resistance and insulation are generally correct, especially if the fault is not
present when analysing (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, 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 their 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.

Defect modes
Motorised throttle valve
In defect mode, the motorised throttle valve can have 6 different statuses.
Type 1
The throttle opening is less than the Safe mode position. The throttle is no longer activated and is
automatically in Safe mode. The ESP, distance control and cruise control/speed limiter systems are
disabled. The automatic transmission is in "Safe mode".
Type 2
The throttle opening is no longer actuated. The engine speed is limited by injection cut-off.
Type 3
Defect mode is associated with restructuring of the pedal setpoints (constant pedal setpoint for each gear).
Type 4
The associated defect mode restricts the throttle opening. The maximum throttle valve opening threshold
results in a speed below 54 mph (90 km/h).
Type 5
The computer no longer processes torque changes requested by the ESP, distance control, cruise control/
speed limiter and automatic gearbox systems.
This defect mode results from a computer malfunction, or a fault with the manifold or turbocharging
pressure sensor.
The system then only uses the accelerator pedal signal.
The ESP, distance control and cruise control/speed limiter systems are disabled. The automatic
transmission system is in Safe mode.
Type 6
The turbocharging valve no longer works.
