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): CLIO III, Laguna II ph 1 and 2
Vel-Satis ph1 and 2,
Espace IV ph1 and 2,
Mégane II, Scénic II, Modus ph2Computer name: Parking distance control
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 a Renault card,
with the vehicle card in the card reader,
press and hold start button (longer than 5 seconds) with start-up conditions not fulfilled,
connect the diagnostic tool and perform the required operations.
For vehicles with key/radiofrequency remote control, use the key to switch off the ignition.
For vehicles with a Renault card,
press the Start button twice briefly (less than 3 seconds),
ensure that the + after ignition feed has been cut off by checking that the computer indicator lights on the
instrument panel have gone out.

5. FAULT FINDING LOG
You will always be asked for this log:
●when requesting technical assistance from Techline,
●for approval requests when replacing parts for which approval is mandatory,
●to be attached to monitored parts for which reimbursement is requested. The log is needed for warranty
reimbursement, and enables better analysis of the parts removed.
6. SAFETY ADVICE
Safety rules must be observed during any work on a component to prevent any damage or injury:
–check the battery voltage to avoid incorrect operation of computer functions,
–use the appropriate tools,
–do not touch the xenon bulbs, and do not work on the COSLAD system when it is in operation, as the voltage can
be above 20,000 V. IMPORTANTIMPORTANT
Any fault on a complex system requires thorough fault finding with the appropriate tools. The
FAULT FINDING LOG, which should be completed during the procedure, enables you to keep
track of the procedure which is carried out. It is an essential document when consulting the
manufacturer.
IT IS THEREFORE ESSENTIAL THAT THE FAULT FINDING LOG IS FILLED OUT EVERY TIME IT IS
REQUESTED BY TECHLINE OR THE WARRANT RETURNS DEPARTMENT.

Fault finding - System operation
Description of operation
The system consists of four sensors built into the rear bumper, a computer and a buzzer.
The system assists the driver during parking manoeuvres by warning of any obstacles to the rear of the vehicle.
–The sensors and the computer calculate the distance between the vehicle and any obstacles. The sensors operate
over a distance range from 20 - 30 cm minimum to 150 cm maximum.
–The driver is informed of the distances by a buzzer.
–The system only works when the vehicle is in reverse gear. Activation is indicated by a brief 0.5 second
activation sound.
The buzzer is activated when the vehicle is 150 cm from the obstacle. As the distance diminishes, the frequency of
the buzzer increases. When the distance reaches 20 - 30 cm, the buzzer becomes continuous.
–The system can only be activated in + after ignition feed.
DEACTIVATING THE SYSTEM:
–The parking distance control can be deactivated in two ways:
–Temporary deactivation: briefly pressing (1 second) the parking distance control switch on the dashboard
deactivates the system (the red warning light on the switch comes on). The function can be switched on again by
pressing briefly for a second time (the red indicator light on the switch goes out) or by switching the ignition off and
back on.
–Permanent deactivation: the parking distance control system can be deactivated for a longer period by pressing
and holding (for approximately 3 seconds) the parking distance control switch on the dashboard (the red warning
light on the switch comes on). The function can be switched on again only by pressing and holding the switch
again (the red warning light on the switch goes out).
Fault finding:
A low pitched, 5-second continuous warning sound upon switching on the ignition informs the driver that a
system fault has occurred.Note:
Using the diagnostic tool statuses, it is possible to find out the function status (ready, detecting, suspended or
disabled) by using status ET003 Parking distance control function (see conformity check or the relevant
status interpretation).
