After replacing or updating the automatic transmission or transmission control unit, old adaptation values must be deleted and a new adaptation run. After finished diagnostic function, a manual adaptation should be run.
Adaptation can only be run when the transmission has reached working temperature (65-110°C). Read off the transmission's oil temperature in data list parameter.
Test conditions:
Ignition on, engine off.
Transmission in neutral.
Transmission temperature between 65 and 110°C.
No faults in the system.
Procedure:
Start the function.
Follow the instructions in the program.
When the function is done, continue with manual adaptation:
Adaptation for shifting N-D and N-R is done with the parking brake applied. Start the car and let it idle. Shift from N to R. Leave R engaged for more than three seconds, then shift to N. Repeat this five times. Then shift to N and D in the same way as above, repeat five times.
Adaptation of upshift and downshift is done when driving on road. Engage D and accelerate to just above 50 km/h with accelerator pedal in constant position (pressed down approx. 15-20%) until fourth gear is engaged. Brake until the car stops. Acceleration up to 50 km/h must take more than 30 seconds and braking must take more than 14 seconds. Repeat the above five times.
Adaptation of manual shifting from second to first gear is done on the road. Engage M2 with the gear selector. Accelerate to 25 km/h. Engage M1 and brake smoothly until the car has stopped. Repeat this ten times.
The function is done.
If the function fails, check the test conditions and repair any faults.
