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.

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.
