E46 Driver Information

Introduction

The driver information system is presented to the driver in two main areas, the instrument

cluster and the center console area. The E46 makes extensive use of bussing for commu-

nication between control modules and reduction in wiring.

The instrument cluster in the E46 is similar in design to the basic cluster installed in the E39.

It uses the pictogram display block for check control and lamp failure warnings.

The Bus links used in the E46 include:

The K-Bus: For communication between all body modules and driver information systems.

The CAN Bus: For communication between the engine management control modules and

the instrument cluster.

The D-Bus: For diagnostic communication between the vehicle and the DIS and MoDiC

testers.
