Purpose of the System
The instrument cluster displays status information about different operating systems in the vehicle. The information is received using dial gauges, LCD display, warning LEDs and sound tones.
- Z8 instrument cluster is based on the E39 technology (base version). Due to the limited space available in the Z8, the indicator instruments have been separated from the electronics. The resulting indicator modules are connected with the electronic control (instrument cluster module) through a separate wiring harness.
- The instrument cluster consists of 7 modules, 4 modules with pointer instruments (stepper motor driven) and 3 modules with displays and control. The instrument cluster control module (IKE) contains the necessary electronics to control the modules.
- The IKE is connected to the vehicle wiring harness and contains the three bus interfaces - Diagnosis bus, K-bus, and Can-Bus.
