Faults
Faults are declared present or stored (depending on whether they appeared in a certain context and have
disappeared since, or whether they remain present but are not diagnosed within the current context).
The present or stored status of faults should be considered when using the diagnostic tool after the + after ignition
feed is switched on (without any action on 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 Notes section.
If the fault is confirmed when the instructions 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 when 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.

Wiring check
Fault finding problems
Disconnecting the connectors and/or manipulating the wiring may temporarily remove the cause of a fault.
Electrical measurements of voltage, resistance and insulation are generally correct, especially if the fault is not
present when the analysis is made (stored fault).
Visual inspection
Look for damage under the bonnet and in the passenger compartment.
Carefully check the fuses, insulators and wiring harness routing.
Look for signs of oxidation.
Physical inspection
While manipulating the wiring, use the diagnostic tool to note any change in fault status from stored to present.
Make sure that the connectors are properly locked.
Apply light pressure to the connectors.
Twist the wiring harness.
If there is a change in status, try to locate the source of the fault.
Inspection of each component
Disconnect the connectors and check the appearance of the clips and tabs, as well as the crimping (no crimping on
the insulating section).
Make sure that the clips and tabs are properly locked in the sockets.
Check that no clips or tabs have been dislodged during connection.
Check the clip contact pressure using an appropriate model of tab.
Resistance check
Check the continuity of entire lines, then section by section.
Look for a short circuit to earth, to + 12 V or with another wire.
If a fault is detected, repair or replace the wiring harness.

Replacing the transmission computer:
Remove the automatic transmission computer (see MR 370 mechanical, 23A, Automatic transmission,
Automatic transmission computer, Removal - Refitting).
Refit the automatic transmission computer (see MR 370 mechanical, 23A, Automatic transmission,
Automatic transmission computer, Removal - Refitting).
Establish dialogue with the diagnostic tool.
Use command VP001 Enter VIN.
Run command VP009 Write last After-Sales Service operation date.
Do not carry out any automatic programming if replacing the automatic transmission computer. Automatic
programming is finalised when the vehicle is driven.
In order to optimise the automatic programming before delivering the vehicle to the customer, apply the
"Programming procedure" shown below.
Replacing the hydraulic distributor:
Remove the transmission hydraulic distributor (see MR 370 mechanical, 23A, Automatic transmission,
Hydraulic distributor, Removal - Refitting).
Refit the transmission hydraulic distributor (see MR 370 Mechanical, 23A, Automatic transmission, Hydraulic
distributor, Removal - Refitting).
Replacing the automatic transmission
Remove the transmission (see MR 370,Mechanical, 23A, Automatic transmission, Removal - Refitting).
Refit the transmission (see MR 370, Mechanical, 23A, Automatic transmission, Removal - Refitting).
Establish communication with the diagnostic tool.
Initialise all the programming, use the command RZ009 Self-adapting clearing (Vdiag05 only).
Run command VP009 Write last After-Sales Service operation date.
The self-programming functions are performed when the vehicle is being driven.
In order to optimise the automatic programming before delivering the vehicle to the customer, apply the
"Programming procedure" shown below.
* APV: After-SalesPROGRAMMING PROCEDURE:
Programming conditions:
The automatic gearbox oil temperature should be between 60˚C and 100˚C.
Stationary, engine running, brake pedal depressed:
Engage neutral at least 5 times to consolidate the programming.
While driving:
Engage the same gear at least 5 times (i.e. in the same conditions) to consolidate the programming.
Note:
Gear changes are slow and harsh the first few times the vehicle is driven, until the automatic transmission computer
has carried out its automatic programming.
During upshifts and downshifts, the system analyses variations in oil pressure, components (play in the brakes and
clutches, changes to spring stiffness due to ageing) and input torque, then corrects them in order to maintain the
quality of gear changes.
The system analyses the turbine speed during the 3 phases of drag reduction (selection of Neutral when stationary,
regulation during drag reduction and deselection of Neutral) and corrects this speed by adjusting the converter
lock-up solenoid valve pressure.

NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present after:
–in the event of open circuit or short circuit-:
–+ after ignition feed and change of lever position.
–in the event of short circuit+:
–+ after ignition feed, initial lever position: Position "P", "R", "N" or "D".
Effect on system:
The lever value is held at its previous valid position until the fault is confirmed. Then
the lever position becomes DRIVE (internal software variable) irrespective of the fault.
–If the fault is present and the lever in position "P", the transmission is in "N", hydraulic
neutral.
–If the fault is present and the lever in position "R", the transmission is in "R", hydraulic
reverse.
–If the fault is present and the lever in position "N", the transmission is in "N", hydraulic
neutral.
–If the fault is present and the lever in position "D", the transmission is in "D", hydraulic
forward gear.
lock-up is inhibited.
Customer complaint:
No lever position display on the instrument panel following fault confirmation and
starting impossible.
If the engine is already running when the fault occurs, there is jolting when shifting from
"P" or "N" to "R" or "D".
Fault warning light comes on.
Use the Wiring Diagrams Technical Note, SCENIC II ph2.
Note:
It is possible to produce this fault if the driver or operator voluntarily keep the lever between two normal positions
for longer than 2 seconds.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition, wait 1 minute and carry out a road test followed by another
check with the diagnostic tool.
