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.

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.

PARKING PROXIMITY SENSOR FUNCTION
NOTESSpecial notes:
If the parking proximity sensor system is suspended or deactivated, the parking
proximity sensor switch indicator light comes on.
This status indicates whether the parking distance control system is on or off:
ET003: READY This means that, when reversing, the parking distance control detects
obstacles and the buzzer sounds (the parking distance control switch
indicator light goes out).
ET003: DETECTING This information is displayed when reverse gear is engaged.
This status indicates that the parking distance control system has
detected an obstacle.
ET003: SUSPENDED This means the parking distance control system is switched off
(no detection possible). The suspension is temporary because the
parking distance control system will come back on after the ignition
is switched off and on. Briefly pressing the parking distance control
switch enables the system to be suspended or reactivated manually.
ET003: DEACTIVATED This means the parking distance control system is switched off
(no detection possible). This suspension is permanent (switching
the + after ignition off and on again will not reactivate the system).
Pressing and holding (3 seconds) the parking distance control
switch enables the system to be deactivated or reactivated.
Check the condition of the fuses F6 (15A), F42 (10A), and replace them if necessary.
If the status does not function as described, check the + 12 V supply on connection LPD between components
1440 and 1016. Check for earth on connection MAN of the connector of component 1440.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check for a + 12 V supply on connection AP3. Check for an earth on connection MG of the connector of component
1222.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
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.

SHORTEST DISTANCE CALCULATED
NOTESSpecial notes:
Before searching for a fault with this parameter, make sure that 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.
This parameter is an average calculated by the computer when an obstacle is
placed between two sensors.
When below 30 cm, the estimated distance is displayed as 0 cm (critical detection
zone with constant warning sound).
With the vehicle close to an obstacle (between 0 and 150 cm), check whether the calculated distance is consistent.
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 distance calculated is still inconsistent or if it is continuously displayed as 255 cm, check the condition of the
sensors; the detection part (metallic outer part) must not have any scratches.
Replace the defective sensor.
If the fault is still present, apply the fault finding procedure to the sensor with the inconsistent distance parameter
(even if the diagnostic tool does not detect a fault), consult interpretation of faults, DF002 “Left-hand outer
sensor”, DF003 “Left-hand inner sensor”, DF004 “Right-hand outer sensor”, DF005 “Right-hand inner
sensor”.
AFTER REPAIRRepeat the conformity check from the start.

ALP3 Buzzer sounds continuously (no obstacle detected)
NOTESOnly investigate this customer complaint after a full check using the diagnostic tool
(there must be no present or stored faults).
With no obstacle in front of the rear bumper (less than 150 cm away), check that the distance parameters on the
diagnostic tool display 0 cm for the “out of detection range” (PR001 “Left-hand outer sensor distance”, PR002
“Left-hand inner sensor distance”, PR003 “Right-hand outer sensor distance”, PR004 “Right-hand inner
sensor distance”).
If the parameters display a setting even though there is no obstacle in front of the rear bumper, make sure nothing
is interfering with the reading (sticker, mud, snow etc. on the rear bumper).
Repair if necessary.
WARNING
If heavy rain falls directly on to the head of the sensor (membrane), or if the sensor encounters certain noises
(pneumatic drill/hammer), the sensor may pick up these vibrations/waves and this may lead to random beeps. Do
not replace the sensor but inform the customer.
Switch off the ignition, and disconnect the parking proximity sensor
computer connector to check the insulation and continuity and ensure
the absence of interference resistance on the following connections:
Connection code 151R,
Connection code 151S.
Between components 1222 and 1223.
If the connection or connections are faulty and there is a repair procedure
(see Technical Note 6015A, Electrical wiring repair, Wiring:
Precautions for repair), repair the wiring, otherwise replace it.
Note:
The line coming from connection 151R of the computer must be insulated
against + 12 V and the line coming from connection 151S of the computer
must be insulated against the earth.
Repair if necessary (see vehicle wiring diagram).
Is the fault still present?
YES
End of fault finding procedure.
NOEnd of fault finding
procedure.
