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.
