Resetting Condition Based Service

Bavarian Technic

Using Bavarian Technic, simply click on the CBS button and you will see the following screen:

This display shows the service item followed by the number of times the item was serviced shown in parentheses.

For example:
Condition Engine Oil (1) 86% would mean the oil has been changed 1 time and there is 86% time and distance remaining.

If CBS is not reset at the time the service is done, the CBS values may need to be adjusted accordingly.

CBS values can be adjusted using Bavarian Technic. To adjust values, click on the adjust value button. You can enter in the service number and the remaining percentage.

The vehicle displays both time and distance until the next service for each component. Though internally these values are stored as a simple percentage, when adjusting values consideration of both time and distance should be taken into account.
