To cut off + after ignition, proceed as follows:
–Disconnect the diagnostic tool.
–Press the Start button twice briefly (less than 3 seconds).
–Ensure that the + after ignition feed has been cut off by checking that the computer indicator lights on the
instrument panel have gone out.
Faults
Faults are declared either present or stored (depending on whether they appeared in a certain context and
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 switched on
after the + after ignition feed (without any system components being active).
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. Note:
The left and right-hand xenon bulb computers are supplied when the dipped headlights are lit.
Therefore fault finding can only be carried out on them after the ignition has been switched on in fault finding mode
(forced + after ignition feed) and the dipped headlights have been switched on.
A synopsis of the general procedure to follow is provided on the following page in the form of a flow chart.

PROGRAMMING
●VP001 Enter VIN:
As it is necessary to enter the VIN each time dialogue is established with the diagnostic tool, it must be
programmed into each vehicle computer whenever a computer is replaced.
Programming procedure:
–Connect the diagnostic tool.
–Consult the fault finding procedure for the automatic transmission.
–Select configuration VP001 Enter VIN.
–Enter the VIN.
–Exit fault finding mode.
–Switch off the ignition.
–Wait for the end of Power-latch: over 10 seconds.
●VP009 Enter last After-Sales operation date:
Every time work is carried out on the automatic transmission in the workshop, enter the date of the
operation.
Select command VP009 Enter last After-Sales operation date on the diagnostic tool, then use the tool's
keypad to enter the date of the operation.
●VP015 Transfer oil condition meter:
Transfer the oil wear counter code from the old computer.
Select command VP015 Transfer oil wear counter on the diagnostic tool, then use the keypad to enter
the code found on the replaced computer.
●VP016 Enter gearbox oil service date:
Select command VP016 Enter gearbox oil service date on the diagnostic tool, then use the keypad to
enter the date found on the replaced computer.
* The immobiliser warning light will flash a few seconds after the ignition is switched off.
