Fault finding - Introduction
1. SCOPE OF THIS DOCUMENT
This document presents the fault finding procedure applicable to all computers with the following specifications:
2. PREREQUISITES FOR FAULT FINDING
Documentation type
Fault finding procedures (this manual):
–Assisted fault finding (integrated into the diagnostic tool), Dialogys.
Wiring Diagrams:
–Visu-Schéma (CD-ROM), paper.
Type of diagnostic tools
–CLIP + multiplex line sensor
Special tooling required
3. RECAP
To run fault finding on the vehicle computers, switch on the ignition.
Depending on the type of vehicle equipment, proceed as follows:
To cut off the + after ignition feed, proceed as follows:Vehicle(s): New Twingo
Function concerned: Parking distance controlComputer name: Parking proximity sensor
Vdiag No.: 04 08
Special tooling required
Multimeter
Elé. 1681 Universal bornier
For vehicles with radio frequency remote control/key,
switch on the ignition with the key.
For vehicles with key/radio frequency remote control,use the key to switch off the ignition.

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.
