Resetting adaptation and the fluid quality counter





Resetting adaptation

Resetting adaptation and counter for "Transmission oil, changing"

Hint: The transmission has torque-controlled, adaptive pressure control. The pressure control means that the transmission itself controls the pressure during each shift sequence in order to avoid harsh shifting. Each shift is assessed by the transmission control module (TCM) and is stored in the internal memory, which results in compensation for wear in the transmission and clutch. In order for the transmission to function correctly after repair, it is important to reset the adaptation in the memory. Since the oil is changed during the repair, the counter for "Transmission oil, change" shall also be reset. If the counter is not reset when draining/changing oil, there is a risk that a diagnostic trouble code may be generated under incorrect conditions.

Note! This applies only if the transmission or one of the components in the transmission have been replaced.




- Ignition on
Activate reset of the adaptation and the counter by clicking on the symbol for VCT2000.

Hint: Select Diagnostics/car communication.

- Start the engine.
Test drive the vehicle following: Test drive schedule, description Test Drive Schedule, Description
Check that the transmission does not display any obvious function faults.

Note! When test driving, the oil temperature must be above 20 °C.
