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

REPLACING THE COMPUTER
If Techline approves the computer replacement, proceed as follows:
–Note the gearbox oil condition meter code in the Identification menu: ID018 Oil condition meter and the
date of the last gearbox oil service ID017 Gearbox oil service date.
–Switch off the ignition.
–Replace the computer.
–If necessary, change the computer configuration in the Enter configuration menu.
–Enter the VIN into the computer with diagnostic tool command VP001 Enter VIN.
–Enter the oil condition meter code from the old automatic transmission computer (found in the Identification
menu) using command VP015 Transfer oil condition meter.
–Enter the gearbox oil service date with command VP016 Enter gearbox oil service date.
–Enter the After-Sales service date with diagnostic tool command VP009 Enter last After-Sales service
date.
–Carry out a check with the diagnostic tool, on the Identification screen.
–Switch off the ignition.
REPLACING AN AUTOMATIC TRANSMISSION COMPONENT
To replace other components of the automatic transmission, (see MR 364 Mechanical, 23A, Automatic
transmission (for MEGANE II) and see MR 370 Mechanical, 23A, Automatic transmission (for SCENIC II)).
After replacing one or more automatic transmission components, or after reprogramming, auto-program the solenoid
valves using command RZ005 "Auto-adaptives" (see Dealing with command modes).IT IS ESSENTIAL TO CONTACT YOUR TECHLINE BEFORE REPLACING AN AUTOMATIC TRANSMISSION
COMPUTER.

Fault finding - Configurations and programming
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.
