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 used following
the + after ignition supply being switched on (without operating 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 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 data that does not produce a fault on the diagnostic tool because 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 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 complaints.
A synopsis of the general 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.
Tactile 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 to another wire.
If a fault is detected, repair or replace the wiring harness.

Check that the parking distance control system is activated using status ET003
“Parking distance control” function (parking distance control switch indicator light
off) and check that status ET001 “Reverse gear engaged” shows “YES”.
If the status displays “suspended” or “deactivated”, restart the system by pressing
for 1 or 3 seconds, consult the interpretation of status ET003 “Parking distance
control function”.
Check, when the vehicle is close to an obstacle (between 26 and 150 cm), that the
distance evaluated corresponds to the distance displayed by the diagnostic tool
(PR001 to PR004).
If the distance is inconsistent or if the distance parameters remain at 0 cm, consult
the interpretation of faults DF002 “Left-hand outer sensor”, DF003 “Left-hand
inner sensor”, DF004 “Right-hand outer sensor”, DF005 “Right-hand inner
sensor”.
Check that status ET001 “Reverse gear engaged” is “YES”. Check that the buzzer
volume is not at a zero setting (LC001: ZERO).
If the configured volume is ZERO, reconfigure the computer using command CF001
Buzzer volume. Select the volume setting preferred by the customer (ZERO, MINIMUM,
VERY LOW, LOW, MEDIUM, HIGH, MAXIMUM).
Switch off the ignition, and disconnect the parking distance control computer to check
the insulation and continuity and the absence of interference resistance on the
following connections:
Connection code 151R,
Connection code 151S.
Between components 1222 and 1016.
If the connection or connections are faulty and if there is a repair procedure (see
Technical Note 6015A, Electrical wiring repair, Wiring: Precautions for repair),
repair the wiring or replace it.
Check the condition of the buzzer and that it is operating correctly.
Measure the resistance between the buzzer's two tracks.
Replace the buzzer if its resistance is not approximately 48 ΩΩ Ω Ω
.
If the fault is still present, replace the buzzer.
AFTER REPAIRRepeat the conformity check from the start.

NOTESSpecial notes:
Before searching for a fault with these parameters, make sure no fault is present or
stored. If there is a fault, apply the interpretation for the fault detected by the
diagnostic tool.
Note:
The ultrasonic sensors are very fragile. Therefore, when removing the rear bumper,
be careful not to scratch them.
If the distance displayed equals 0 cm, there are two possible reasons:
1no obstacle has been detected (therefore this is the default value)
2The sensor is malfunctioning, check that there are none of the following faults:
DF002 “LEFT-HAND OUTER SENSOR”, DF003 “LEFT-HAND INNER SENSOR”,
DF004 “RIGHT-HAND OUTER SENSOR”, DF005 '“RIGHT-HAND INNER
SENSOR” and apply the relevant fault finding procedure
Wen the vehicle is close to an obstacle (between 26 and 150 cm), check that the distance evaluated corresponds
to the distance displayed by the diagnostic tool (PR001 to PR004).
If the distance is inconsistent when there is an obstacle present, check that there is nothing interfering with the
measurement (sticker, mud, snow on the rear bumper, etc.).
If the distances displayed by the sensors are inconsistent, check the condition of the sensor(s), check the condition
of the button using status ET003 “Parking distance control function” and ET004 “Parking distance control
switch”. There must be no scratches on the detection component (outer metal section) of the sensors.
Replace the defective sensor.
If the fault is still present, apply the fault finding procedure to the sensor whose distance parameter is incorrect
(even if the diagnostic tool does not report a fault).
AFTER REPAIRRepeat the conformity check from the start.
