Service Function: Reset CBS Condition Based Service
The scope of maintenance work can be reset with the "Reset CBS Condition Based Service" service function. Even when the availability is above 80 %. The reset via the BMW diagnosis system has the advantage that the on-board date is corrected automatically.
The individual maintenance scopes are displayed in the BMW diagnosis system with service counter and availability.
- The service counter is increased by one count on resetting. In new vehicles all service counters are set to "1".
The service counters are used in the Service Acceptance Module (SAM) to control the additional work for specific maintenance operations.
- On resetting the availability is set at 100%. The percentage availability is the wear value for the maintenance operation.
The greater the availability, the further away the next service.
0% means that the maintenance measure must be carried out.
