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.

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,
–oil temperature ≤ - 40 ˚C,
–vehicle speed > 6 mph (10 km/h).
–in the event of short circuit-:
–+ after ignition feed,
–oil temperature > 180 ˚C,
–vehicle speed > 6 mph (10 km/h).
–accelerator pedal > 12.5 % and engine speed > 305 rpm.
(detection time in the event of short circuit- is 10 minutes).
Effect on system:
–in the event of open circuit or short circuit+:
Gear change quality is reduced.
lock-up is inhibited.
–in the event of short circuit-:
The transmission operates as if the temperature had increased.
Customer complaint:
–in the event of open circuit or short circuit+:
If the fault occurs while driving, the transmission engages fixed 5th gear.
Restarting is in 3rd gear.
Gear change quality is reduced.

Use the Wiring Diagrams Technical Note, SCENIC II ph2.
Check that the coolant temperature (see 13B, Diesel injection, EDC16, CP33 M9R 721 Conformity check)
is ≥ - 40 ˚C (the transmission oil temperature sensor is within its operating range).
If the oil temperature ≤ - 40 ˚C, move on to step 1.
If the oil temperature is ≥ - 40 ˚C, deal with the fault; move on to step 2.
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.
