Instrumentation Bus (I-Bus)

Instrumentation bus (I-bus)
The instrumentation bus (I-bus) is one of three information links (data link/serial) via a data link to other control units. The instrument bus is monitored by the instrument cluster electronics ( IKE ). The IKE also sets up the interconnection of the bus systems:
- I-bus (instrumentation bus)
- K-bus (body bus)
- Diagnosis bus (link to diagnostic socket),
- CAN bus (instrument cluster-integrated version phased-in as from 5/97) (gateway function).
