CO.0 : Open circuit or short circuit to earth
1.DEF : Internal electronic fault
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 Right-hand inner sensor
Track 9 Track 1
Track 13 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.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault reappears present or stored after its has been cleared, the ignition is switched
on and off again and reverse gear is selected.
Special notes:
The sensors are directly supplied with + 12 V by the computer.
Computer with 1 connector:
With the parking distance control computer 16-track connector connected and with the ignition on, measure the
sensor power supply coming from the computer. The voltage should be equal to the battery voltage (± 0.5 V)
when measured across track 9 (+ 12 V) and track 10 (earth).
If there is not a + 12 V power supply between the tracks specified above, remove the rear bumper to access the
sensors.
Computer with 2 connectors:
With the parking distance control computer 12-track connector connected and with the ignition on, measure the
sensor power supply from the computer outlet. The voltage should be equal to the battery voltage (± 0.5 V) when
measured across track 11 (+ 12 V) and track 8 (earth).
If there is not a + 12 V power supply between the tracks specified above, remove the rear bumper to access the
sensors.
Switch off the ignition, and disconnect the parking distance control computer connector to check the insulation
and continuity and the absence of interference resistance on the following connections:
1 connector:
Parking proximity sensor computer connector Sensors
Track 9 Track 1 of the four sensors
Track 10 Track 3 of the four sensors
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.

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).
AFTER REPAIRCheck that the system is operating correctly.
