Driver Information: Introduction
Depending on the model and equipment installed, the X5 is equipped with either the high version E38/E39 or the base version Instrument Cluster - Driver information systems. The wiring harness is similar to the E38/E39 systems with minor changes made for functional changes with control modules.
The X5 continues to make use of multi-information bus communication systems. They offer the advantages of:
- A high level of reliability
- Reduction in the size of the harnesses
- Multiple utilization of sensor and signal inputs
- Expanded functions through increased data flow
- Flexibility in configuring the systems
- Reduction in cost
- Expanded diagnostic capabilities
The CAN bus link to the Instrument Cluster provides expanded communication for all vehicle functions to share engine/drivetrain data with the body electrical systems. The cluster is an important link in the system, and vital information is updated faster to the control modules.
