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:

Check that the parking distance control system is switched on using status ET003
"Parking distance control function" (parking distance control switch warning light
goes out). If the status displays “suspended” or “deactivated”, restart the system by
pressing for 1 or 3 seconds, consult the interpretation of status ET003 “Parking
distance control function”.
Check that the parking distance control configuration is correct for the vehicle on
which it is fitted (LC005 Vehicle identification). If necessary, reconfigure the
computer using command CF005 Vehicle identification.
Check, when the vehicle is close to an obstacle (between 20 and 150 cm), that the
distance evaluated corresponds to the distance displayed by the diagnostic tool
(PR001 to PR004).
If the distance reading does not match or the distance parameters stay at 255 cm,
contact your Techline.
Check that the buzzer volume is not at a zero setting LC001 Buzzer volume.
If the configured volume is ZERO or DEACTIVATED, reconfigure the computer using
command CF001 Buzzer volume. Select the volume required by the customer.
Switch off the ignition, and disconnect the parking distance control computer 16-track

SHORTEST DISTANCE CALCULATED
NOTESSpecial notes:
Before searching for a fault with this parameter, make sure that no fault is present or
stored. If there is a fault, apply the interpretation for the fault detected by the
diagnostic tool.
Note:
The ultrasonic sensors are very fragile. Therefore, when removing the rear bumper, be
careful not to scratch them.
This parameter is an average calculated by the computer when an obstacle is
placed between two sensors.
When below 30 cm, the estimated distance is displayed as 0 cm (critical detection
zone with constant warning sound).
Using the diagnostic tool configuration reading screen, check that the parking distance control system is configured
correctly for the body on which it is fitted LC005 Vehicle identification). If necessary, reconfigure the computer
using command CF005 Vehicle identification.
With the vehicle close to an obstacle (between 0 and 150 cm), check whether the calculated distance is consistent.
If the distance is inconsistent or if the parameter remains at 255, ensure that nothing is interfering with the
measurement (sticker, mud or snow, etc. on the rear bumper).
If the distance calculated is still inconsistent or if it is continuously displayed as 255, check the condition of the
sensors; the detection part (metallic outer part) must not have any scratches.
Replace the defective sensor.
If the fault is still present, apply the fault finding procedure to the sensor whose distance parameter is incorrect
(even if the diagnostic tool does not report a fault).
AFTER REPAIRRepeat the conformity check from the start.
