Adaptation, resetting

Adjustment
After changing or updating automatic transmission, TCM or software, the old adaptation data must be removed and a new adaptation performed as described below.

Note
Zeroing adaptation has taken place automatically if "Add" has been executed in Tech 2.

1. Reset adaptation using Tech2 by adapting the values at Automatic transmission - Adjustments Reset.
2. Operate the transmission to working temperature (65 - 110° C). Read from Tech2 menu "Read values" TCM.

Important
The automatic gearbox must not be warmed up by a stall test.

Note
Adaptation can be carried out only when the transmission has attained working temperature.

3. Adaptation for shifting N-D and N-R is carried out with the handbrake applied. If the procedure is done in the workshop, connect an exhaust ventilator, start the car and run at idling speed. Shift from N to R. Keep R engaged for more than three seconds, then shift back to N. Repeat the procedure 5 times. Then shift from N to D the same as above, repeating the steps 5 times.





4. Adaptation for shifting up and down is done by driving on a road. Engage D and accelerate up to just over 50 km/h with the accelerator pedal at a constant position (approx. 15 - 20% depressed) until 4th gear has engaged. Brake until the car is stopped. Acceleration up to 50 km/h must take more than 30 sec. and braking must take more than 14 sec. Repeat the above 5 times.





5. Adaptation for manual shifting from 2nd to 1st gear is carried out on-road. Engage M2 with the selector lever. Accelerate to 25 km/h. Engage M1 and brake smoothly until the car is stationary. Repeat this procedure 10 times.





6. Check that adaptation has had the desired effect and that shifting performance has improved.
