Note. When an automatic transmission computer is replaced, it is necessary to memorize the new computer with the value of the gearbox oil life stored in the memory of the replaced computer.
Note. Proceed as follows: read the oil life data from the ECU to be replaced using parameter PR133 «Odometer until next oil change» and write them down.
Replace ECU.
Enter the oil life data into the memory of the new ECU using the command: CF320 «Transferring odometer data until the next oil change».
Check data entry by parameter output «Odometer until next oil change».
Enter after-sales service date with command: CF320 «Post-sales date record».
Carry out a road test to memorize the entered parameters with the new ECU.
