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).

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:
Parking distance control computer Left-hand outer sensor
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.
