Using the Reset and Delete Functions window

Diagnosis provides the following delete functions:

Delete TIM data

Delete adaptation data

Delete operating data

Delete the oil ageing index after oil change

Delete trend data of the oil level check

Delete service data

Reset the shift program configuration

Clear the history storage

Clear the slip storage

For the RESET functions that are available in the individual user levels (access authorizations), please refer to: User level.

Click Service > Reset functions in the main window. All the appropriate data is read automatically from a connected transmission control unit.

You can see in the "Start Delete Job" column whether this delete function is available in your user level. Click the switch to start a delete job.

The TIM (Transmission Identification Module) is the electronic rating plate of a DIWA / NOWA transmission. It contains information on the transmission design. TIM data is essential for a correct functioning of the transmission software. This is why this data must never be deleted. The "Delete TIM data" function is therefore available only in development and production. For further information, please see: TIM.

Adaptation is the automatic (self-learning) adaptation of the shifting operations to different operating conditions. The transmission software is optimized to low wear and high shifting comfort. Deviations from setpoints for disk slip times are corrected by changing the control pressure profile. After a transmission has been overhauled or repaired (work on the disks), the adaptation data must be deleted, in order to ensure quick adaptation to the new operating conditions. For further information, please see: Adaptation data.

Operating data are measured values produced during operation that are recorded, classified and cumulated throughout the entire transmission runtime. Operating data is therefore never deleted after an oil change. The "Delete operating data" function is available only in development and production. For further information, please see: Operating data.

The oil ageing index is calculated by the transmission control unit and provides information on the current quality of the transmission oil. The oil ageing index must be deleted after every oil change to be able to calculate the current quality. For further information, please see: Oil ageing index.

The trend data of the oil level check is used to monitor the oil level throughout the entire transmission runtime. This is why this data is never deleted.

During transmission acceptance (PDI - PreDelivery Inspection), the service data must be entered by the Voith customer service. The "Delete service data" function is an option if you have to change many service data entries. For further information, please see: Service data.

The "Reset the shift program configuration" function can be used to restore the basic shift program configuration that is stored in the dataset. Resetting the shift program configuration can only be done on instruction from Voith customer service. For further information, please see: Shift program configuration.

Certain events such as performing a transmission oil change, configuring the shift programs or reprogramming actions are recorded throughout the entire transmission runtime and stored in the history storage of the transmission control unit. This is why this data is never deleted. The "Clear history storage" function is therefore available only in development and production. For further information, please see: History storage.

After a transmission has been overhauled or repaired (work on the disks), the slip storage must be deleted, to ensure proper functioning of the early-warning system.

Click the symbol to stop communication with the transmission control unit. This function is required for debugging tasks only.
