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 complaints.
A synopsis of the general procedure to follow is provided on the following page in the
form of a flow chart.

PRESENT
OR
STOREDCOMPUTER FAULT
1.DEF : Internal electronic fault
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:
If the fault is present and is represented by 1.DEF or 2.DEF, the system operates in
defect mode (substitute values are used).
1.DEF
NOTES None
After following the instructions, if the fault recurs, switch off the ignition and disconnect the supply fuse from the
parking distance control computer F6 (15A).
Reconnect the fuse, switch the ignition back on, and perform a fault reading.
If the fault recurs, check the connections and condition of the parking proximity sensor computer connector (no
damage to the connections).
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
With the ignition switched off, disconnect the parking proximity sensor computer connector to check the
conformity of the feeds and to check the insulation, continuity and the absence of interference resistance
on the following connections:
Connection code AP3,
Between components 1222 and 1016.
Connection code MG.
Between component 1222 and the rear left-hand earth.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, contact the Techline.
AFTER REPAIRClear the stored faults.
Follow the instructions to confirm repair.
Deal with any other faults.
