Adaptation, resetting: Adjustment

When automatic transmission, TCM or software is replaced or updated the old adaptation data must be removed and new adaptation made according to the instructions below

1. Zero the adaptation using Tech2 by going into Automatic Transmission - Activate.
2. Run the gearbox to working temperature (65 - 110°C). Read off on Tech2 as per the Menu "READ VALUES  " TCM.
   IMPORTANT: The automatic gearbox must not be warmed up by a stall test.
   NOTE: Adaptation can only be made when the gearbox has reached working temperature.
3. Adaptation for shifting N-D and N-R is made with the handbrake applied. If the procedure is carried out in the workshop, connect the exhaust evacuation system, start the car and run at idling speed. Shift from N to R. Allow R to be engaged for more than three seconds, then shift back to N. Repeat the procedure 5 times. Next shift from N to D in the same way as above, repeat 5 times.

4. Adaptation for shifting up and down is carried out by driving. Engage position D and accelerate up to just above 50 km/h with the accelerator pedal in a constant position (approx. 15 - 20% depressed) until 4th gear has been engaged. Brake until the car stops. The acceleration must take more than 30 seconds up to 50 km/h and the braking must take more than 14 seconds. Repeat the above 5 times.

5. Adaptation for manual shifting from gear 2 - 1 is carried out by driving. Engage position 3 or M2 (cars with Sentronic) using the selector lever. Accelerate up to 25 km/h. Engage position L or M1 (cars with Sentronic) and brake gently until the car stops. Repeat the procedure 10 times.

6. Check that the adaptation has taken effect and that shifting quality has improved.
