Fault finding - Replacement of components
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.

NOTESSpecial notes:
Use bornier Elé. 1681 for all operations on the computer connectors.
Customer complaint: deterioration in gear shift strategies.
Deal first with faults: DF005 Oil pressure sensor circuit and DF023 Gearbox oil temperature sensor circuit.
Disconnect the battery.
Check the condition and cleanliness of the modular connector connections.
Disconnect the computer. Check the cleanliness and condition of the connections.
Repair if necessary.
Check the insulation, continuity and the absence of interference resistance to earth, to + 12 V of the following
connections:
●connection code 5U, between components 119 and 781,
●connection code 5V, between components 119 and 781,
●connection code 5BC, between components 119 and 754,
●connection code 5BB, between components 119 and 754.
Check the supply of the analogue sensors = 5 V.
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 the wiring.
If the problem is still present, contact the Techline.
