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.

Step 1:
Start the vehicle, check that engine coolant temperature is ≥ 20 ˚C.
If the fault is stored, deal with the other faults displayed on the diagnostic tool. In the absence of faults, end of
fault finding.
If a fault is still present, deal with it, then move on to step 2.
Step 2:
Look for any damage to the harness and check the condition and connection of the automatic transmission
computer and automatic transmission connectors.
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.
Disconnect the connector from component 119, measure the resistance of the oil temperature sensor
(on the connector of component 119) between the following connections:
●Connection code 5BZ,
●Connection code 5BY.
The resistance should be between:
–4.208 ± 0.42 kΩΩ Ω Ω
at 20 ˚C,
–1.947 ± 0.19 kΩΩ Ω Ω
at 40 ˚C,
–0.988 ± 0.09 kΩΩ Ω Ω
at 60 ˚C,
Is the resistance correct?
If YES, contact the Techline.
If NO, move on to step 3.
Stage 3:
Disconnect connector R22 and check continuity and insulation on the following connections:
●Connection code 5BZ,
●Connection code 5BY.
Between components 119 and R22.
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.
Are the continuity and insulation correct?
If YES, move on to step 4.
If NO, replace the external wiring harness on the automatic transmission.
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.

1.DEF: Open circuit or short circuit
NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present after:
–+ after ignition feed,
–with the engine running,
–vehicle speed > 24 mph (40 km/h),
–engine speed > 1500 rpm,
–turbine speed < 600 rpm and accelerator pedal > 0 %.
Effect on system:
Impossible to calculate gear.
Customer complaint:
Gear on which fault occurred is fixed. Restarting in fixed 3rd gear (no more gear
changes). Manual mode is inhibited. Fault warning light comes on.
Use the Wiring Diagrams Technical Note, SCENIC II ph2.
Look for any damage to the wiring harness, and check the condition and connection of the transmission
computer and the turbine speed sensor.
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.
Check for + after ignition feed on connection AP4 of component 1060.
Is the + after ignition feed still present?
If YES, move on to step 1.
If NO, move on to step 2.
Step 1:
Check the continuity and insulation of the following connections:
●Connection code 5HN.
●Connection code 5DA.
Between components 119 and 1060.
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.
Check the intermediate connector R22, if the fault is still present, replace component 1060.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.

LEVER POSITION SWITCH CIRCUIT
1.DEF: Open circuit or short circuit
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.
