PARKING DISTANCE CONTROL SWITCH
NOTESSpecial notes:
Only apply the interpretation of this status if the position of the parking distance control
switch is not consistent with the information supplied by status (“Brief press” or
“Released”).
There must be no present or stored faults.
Check the condition of fuses F6 (15A), F42 (10A) and replace them if necessary.
Check that there is a + 12 V supply on connection LPD between components 1140 and 1016. Check that there is
an 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 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.
With the ignition off, disconnect the parking distance control button connector to check the insulation (against
earth and + 12 V), continuity and the absence of interference resistance on the following connection:
Connection code 151W between components 1222 and 1440.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the connection just checked is OK (no open or short circuit), and there is an earth on track A2 of the switch but
the fault is still present, check the switch operation with an ohmmeter.
Switch not pressed: insulation between connections 151W and MAN.
After pressing the switch: continuity between connections 151W and MAN.
Replace the parking proximity sensor switch if it fails to function as specified.
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

hitch.
If it is incorrectly aligned, realign it or remove it.
Is the fault still present?
YES
Using the diagnostic tool, gradually increase the distance between the central sensors and the ball on the caravan
attachment centimetre by centimetre (this distance enables the threshold point to be redetermined (0 cm) from the
rear of the vehicle depending on the length of the caravan attachment) using configuration VP003 “Caravan
attachment distance” (maximum distance: 35 cm). The caravan attachment distance can be checked with
parameter PR026.
End of fault finding procedure.
