Faults
Faults are declared as either present or stored (depending on whether they appeared in a certain context and have
disappeared since, or whether they remain present but have not been diagnosed within the current context).
The present or stored status of faults should be taken into consideration when the diagnostic tool is used following
the + after ignition supply being switched on (without operating the system components).
For a present fault, apply the procedure described in the Interpretation of faults section.
For a stored fault, note the faults displayed and apply the instructions in the Notes section.
If the fault is confirmed when the instructions in the Notes section are applied, the fault is present. Deal with the fault
If the fault is not confirmed, check:
–the electrical lines which correspond to the fault,
–the connectors for these lines (for oxidation, bent pins, etc.),
–the resistance of the component detected as faulty,
–the condition of the wires (melted or split insulation, wear).
Conformity check
The aim of the conformity check is to check data that does not produce a fault on the diagnostic tool because the
data is inconsistent. Therefore, this stage is used to:
–carry out fault finding on faults that do not have a fault display, and which may correspond to a customer
complaint.
–check that the system is operating correctly and that there is no risk of a fault recurring after repairs.
This section gives the fault finding procedures for statuses and parameters and the conditions for checking them.
If a status is not behaving normally or a parameter is outside the permitted tolerance values, consult the
corresponding fault finding page.
Customer complaints - Fault finding chart
If the test with the diagnostic tool is OK but the customer complaint is still present, the fault should be processed by
customer complaint.
A synopsis of the general procedure to follow is provided on the following page
in the form of a flow chart.

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

PARKING DISTANCE CONTROL FUNCTION
NOTESSpecial note: If the parking distance control system is suspended or deactivated, the
parking distance control switch indicator light comes on.
This status indicates whether the parking distance control system is on or off:
ET003: READY This means that, when reversing, the parking distance control detects obstacles
and the buzzer sounds (the parking distance control switch indicator light goes
out).
ET003:
DETECTINGThis information is displayed when in reverse gear and indicates that the parking
distance control has detected an obstacle.
ET003:
SUSPENDEDThis means the parking distance control system is switched off (no detection
possible). The suspension is temporary because the parking distance control
system will come back on after the ignition is switched off and on. To suspend or
reactivate the system manually, briefly press (1 second) the parking distance
control switch.
ET003:
DEACTIVATEDThis means the parking distance control system is switched off (no detection
possible). This suspension is permanent (switching the + after ignition off and on
again will not reactivate the system). To deactivate or reactivate the system
manually, press and hold (3 seconds) the parking distance control switch.
If the status is not as specified, check for an earth on track A2 of the parking distance control switch. Repair if
necessary.
With the ignition off, disconnect the parking distance control switch to check the insulation (against the earth
and + 12 V), continuity and absence of interference resistance in the following connection:

NOTESSpecial notes:
Before searching for a fault with these parameters, make sure 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.
An obstacle which is further than 150 cm away cannot be detected, the parameter
value is 255 in this case. For an obstacle which is between 20 and 150 cm away, the
parameter value is the distance to the obstacle.
For an obstacle which is closer than 20 cm away, the value of the parameters is 0.
Using the diagnostic tool configuration reading screen (repair mode menu), check that the parking distance
control system is configured correctly for the vehicle type to 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 is incorrect or if the distance parameters remain at 255, make sure nothing is interfering with the
reading (sticker, mud, snow etc. on the rear bumper).
If the distances displayed by the sensors seem incorrect or if 255 is displayed continuously, check the condition of
the sensor(s). There must be no scratches on the detection component (outer metal section) of the sensors.
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.

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.

Check the connection and condition of the connector
on the buzzer.
Replace the connector if necessary.
Using the parameter screen of the diagnostic tool
(PR001, PR002, PR003, PR004), make sure the
proximity sensors are detecting obstacles (between
20 and 150 cm).
Do the parameters specified above display
distance values (with an obstacle in front of the rear
bumper)?
YES
Place an obstacle in front of the rear bumper in order to be able to measure the distance displayed by the
diagnostic tool. During the detection process, make sure the buzzer has the correct power supply by taking a
reading between tracks 1 and 2 of the buzzer.
During this test, is the buzzer receiving power?
YES NO
NOApply the interpretation of parameters
(PR001, PR002, PR003, PR004).
