Ethernet Access: Notes

The increasing number and complexity of functions in the vehicle cause a constantly increasing rise in the number of control units and consequently the data volume in the vehicle. When these data are to be updated the vehicles must be programmed over the BMW programming system. The number of BMW vehicles that can be programmed has constantly increased since the introduction of the E65 in 2001.

The challenge facing the Service Department is the programming of ever increasing data in increasing numbers of vehicles.

In order to accelerate the programming procedure in the workshop, an Ethernet access has been integrated in the diagnostic socket of the F01/F02 in addition to the OBD access (D-CAN).

It is Fast Ethernet compliant with IEE802.3 2005 100 base TX.

This standardized interface provides a centralized, standardized access in the vehicle. This access permits IP-based communication with the vehicle.

The vehicle is therefore uniquely identifiable as a communication partner in an IP-based network, and BMW diagnosis and programming systems can be used in the workshop for the data exchange with the vehicle.

NOTE: The previously used MOST direct access is not installed in the F01/F02.
