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).

Fault finding - Configurations and programming
CONFIGURATION AFTER REPLACING THE COMPUTER
After replacing the computer, configure the parking distance control computer with the vehicle type using
configuration CF005 Vehicle identification (repair mode menu, diagnostic tool configuration function). The
configuration adapts the sensors' detection field to the type of body.
Depending on a vehicle's gearbox type (automatic or manual), the parking distance control can be delayed from
working. Activation of the parking distance control is indicated by a brief 0.5 second activation sound (vehicle in
reverse gear). On vehicles with an automatic transmission, the 3-second delay prevents the activation noise from
sounding every time the driver shifts from Park to Drive.
After having configured the computer, check that the configuration has taken effect by reading the configuration
LC005 Vehicle identification.
Special note (Vdiag 08 only):
If a vehicle is fitted with a caravan towbar and if there is a continuous beeping noise, take the towbar out of the
detection field for the rear sensors, run the command for parameter VP003 Caravan towbar distance, then increase
the detection area centimetre by centimetre. To avoid impairing the detection, the parameter PR026 Caravan towbar
distance must not exceed 40 cm.
SETTING OPTIONS
The volume and the tone of the buzzer can be changed if the customer desires.
Configuration CF001 Buzzer volume is used to adjust the volume of the buzzer.
Configuration function CF006 Pitch adjustment is used to adjust the pitch of the buzzer.
After configuring the computer, check that the configurations have been registered correctly using configuration
readings LC001 Buzzer volume and LC006 Tone adjustment.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present following selection of reverse gear if the parking distance
control function is ACTIVE (READY): the parking distance control warning light is not
lit, see the interpretation of status ET003 Parking distance control function.
Special notes:
This fault is indicated by the buzzer (a 5 second warning sound) and the system shuts
down.
If a combination of faults are present on the sensors:
Check the connection and condition of the intermediate connectors (the sensors up to the computer). Repair if
necessary.
Check for + 12 V, after ignition, between tracks 1 and 3 of all the sensors.
Computer with 1 connector:
Check the insulation, continuity and the absence of interference resistance of the supply for each sensor
(between Tracks 1 and 3) and for the computer (between tracks 9 and 10).
Computer with 2 connectors:
Check the insulation, continuity and absence of interference resistance of the supply between tracks 1 and 3
for each sensor and between tracks 8 and 11 of the computer 12-track connector.
In the case where only one sensor is faulty:
Swap the defective sensor with a non-defective sensor.
Check for faults:
If the sensor is no longer faulty, replace the defective sensor.
If the fault is still present, with the ignition off, disconnect the parking distance control computer connector to
check the insulation, continuity and the absence of interference resistance on the following connections:
1 connector:

Track 9 Track 1
Track 15 Track 2
Track 10 Track 3
Repair if necessary (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for repair),
repair the wiring, otherwise replace the wiring.
AFTER REPAIRClear the stored faults.
Follow the instructions to confirm repair.
Deal with any faults.
