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.

NOTESOnly investigate this customer complaint after a full check using the diagnostic tool
(there must be no present or stored faults).
Using the diagnostic tool Main Data screen, check
that the parking distance control system is on.
The status ET003 Parking proximity sensor
function must be READY (and the red warning light
on the parking proximity sensor switch must be off).
Is status ET003 Parking proximity sensor
"READY"?
YES
Using the diagnostic tool's Main Data screen,
check that reverse gear is selected.
The ET001 Reverse gear selected status must be
YES.
Also ensure that the reversing lights come on when
reverse gear is selected.
Is status ET001 YES?
YES
Using the diagnostic tool configuration readings
screen, check that the buzzer volume has not been
switched off (LC001 Buzzer volume should not be
ZERO).
Is the LC001 function ZERO
NO
NOTurn on the parking proximity sensor by
pressing the switch for 1 or 3 s econds (the
red light should go out).
Note:
For more information concerning the
activation of the system, consult the
interpretation of status ET003 Parking
proximity sensor.
NOApply the interpretation of status ET001
Reverse gear engaged.
YESReconfigure the buzzer volume using the
diagnostic tool (command CF001 Buzzer
volume).
AFTER REPAIRCheck that the system is operating correctly.

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.
AFTER REPAIRCheck that the system is operating correctly.
