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.

ALP4 buzzer sounds continuously (with caravan attachment)
NOTESOnly investigate this customer complaint after a full check using the diagnostic tool
(there must be no present or stored faults).
Make sure it is a Renault caravan attachment.
Check that the cover is correctly aligned with the caravan towing
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.
NOEnd of fault finding
procedure.
AFTER REPAIRCheck that the system is operating correctly.
