Wiring check
Fault finding problems
Disconnecting 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 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 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.

Fault finding – Replacement of components13B
REPLACING THE EGR VALVE (EXHAUST GAS RECIRCULATION VALVE)
After replacing the EGR valve, the computer must store the offset of the new valve (to 0 km), as well as the offset
measured at the time of the last engine cut-off (power-latch). With these data, the computer can detect clogging or
blocking of the EGR valve.
When the valve is replaced, clear the stored offsets so that the program uses the new valve’s offset value. The data
associated with this programming is combined under the EGR programming function.
Procedure to follow after replacement of the EGR valve:
– Select the CLEAR menu.
– Run fault clearing command RZ002 EGR adaptives,
– switch off the ignition,
–wait 30 seconds (auto-supply phase of the computer),
– start the vehicle to allow programming of the EGR valve,
– view parameters PR400 New EGR valve offset and PR129 Last EGR valve offset,
– if the reinitialisation was correctly performed then 0.6 V < PR400 = PR129 < 1.9 V.
REPLACEMENT OF PUMP, INJECTORS, RAIL + RAIL PRESSURE SENSOR OR COMPONENT OF THE LOW
PRESSURE CIRCUIT (DIESEL FILTER etc.).
After replacement of one of these components, carry out clearing using RZ004 Pressure regulation adaptives.
REPLACEMENT OF THE PARTICLE FILTER (Only Vdiag 45, 49, 4D)
After replacement of the particle filter, clear the fault DF308 Clogged particle filter if it is present or stored using
command RZ001 Fault memory. IMPORTANT
It is not possible to try an injection computer coming from the Parts Department because it will no longer be
possible to use it on another vehicle.

NOTESPriorities when dealing with a number of faults:
If there are a number of faults, deal with the other system faults first.
Conditions for applying the fault finding procedure to a stored fault:
The fault is declared present after one attempt to start the engine, or with the engine
running.

IMPORTANT
This fault can result in a rapid and significant fouling of the particle filter.
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and Kangoo II Wiring
diagrams Technical Note.
Check the condition of the fuel supply pipes between the particle filter injector and the electric fuel pump.
Check that the pipes are not trapped, blocked or pierced and there that are no leaks.
Check the condition of the fuel filter and ensure that it is not clogged.
Check that the particle filter injector is not jammed closed or clogged.
(See test 8 Particle filter injector supply circuit check).

If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair) repair the connector(s); otherwise, replace the wiring.
With the ignition on, check the continuity, insulation and absence of interference resistance on the following
connections:
–3TD between components 1287 and 120,
–3XT between components 1287 and 120.
If the connection(s) are faulty and there is a repair method (see Technical Note 6015A, Repairing electrical

CRUISE CONTROL/SPEED LIMITER DEACTIVATION
STATUS DEFINITIONThis status varies according to engine specifications.
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and Kangoo II Wiring
diagrams Technical Note.
Note:
Cruise control can be activated when the vehicle speed exceeds 18 mph (30 km/h).
Status ET415 shows various reasons that cause deactivation of the cruise control/speed limiter function, which
are due to driver action or external factors (for example, STATUS 1).
IMPORTANT:
Erase the fault memory by running the command RZ001 Fault memory to reset this status to WITHOUT.
WITHOUT
This status is WITHOUT when:
– the computer has been reinitialised,
– the computer has been reprogrammed.
STATUS 1Traction control request
If the vehicle is fitted with a traction control system, the cruise control function is
deactivated every time the ABS computer calls for traction control.
Status ET415 becomes STATUS 1 when driving with the cruise control active
(ET042 Cruise control/Speed limiter: CRUISE CONTROL) and when traction control
is requested.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command
RZ001 "Fault memory".
If status ET415 becomes STATUS 1 with no traction control request (see 38C,
Anti-lock Braking System).
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
