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
For the replacement of the other components which make up 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 the replacement of one or more gearbox components, or after reprogramming, auto-program the solenoid
valves using command RZ005: Self-adapting programs (see Dealing with command modes). IT IS ESSENTIAL TO CONTACT YOUR TECHLINE BEFORE REPLACING AN AUTOMATIC TRANSMISSION
COMPUTER.

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.

Reading automatic transmission configuration
The read-configuration commands (LCXXX) are used to display the current computer configuration in relation to the
equipment installed in the vehicle.
Writing automatic transmission configuration
The write-configuration commands (CFXXX) are used to configure the computer for the equipment installed in the
vehicle.
These three settings are important because they optimise transmission operation for the vehicle. If they are not
entered properly, automatic transmission operation may be impaired.Configuration reading Configuration

CONFIGURATIONS OF THE AUTOMATIC TRANSMISSION COMPUTER CF322: ENGINE TORQUE CONTROL
FUNCTION
–This function reduces engine torque when shifting gears.
–To apply this configuration, the vehicle must have the ignition on, engine stopped and gear lever in position P
or N.
–This function tells the computer what torque to apply to the engine when changing gears.
–Select configuration CF322 "Engine torque control function".
–Configure the computer WITH or WITHOUT.
–Exit fault finding mode.
–Switch off the ignition.
–Wait 15 seconds for the power-latch to end.
–re-read the configuration for confirmation.
CF314 "ELECTRONIC STABILITY PROGRAM (ESP)"
–This function limits over- or under-steering by braking certain wheels and controlling engine torque.
–To apply this configuration, the vehicle must have the ignition on, engine stopped and gear lever in position P
or N.
–This function lets the automatic transmission computer downshift for ESP adjustments.
–Select configuration CF314 "Electronic stability program (ESP)".
–Configure the computer WITH or WITHOUT.
–Exit fault finding mode.
–Switch off the ignition.
–Wait 15 seconds for the power-latch to end.
–re-read the configuration for confirmation.
CF325 "SHIFT LOCK CONNECTION FAULT FINDING"
–To apply this configuration, the vehicle must have the ignition on, engine stopped and gear lever in position P
or N.
–Select configuration CF325 "Shift lock connection fault finding".
–Configure the computer WITH or WITHOUT.
–Exit fault finding mode.
–Switch off the ignition.
–Wait 15 seconds for the power-latch to end.
–re-read the configuration for confirmation.
