General Information

Introduction
The instrument cluster is the main Driver Information display unit. The instrument cluster is made up of the IKE and a display unit. This type of cluster is known as a "High version".




As introduced, the IKE control module was mounted on the back of the instrument cluster and was connected to the cluster with a 46 pin ribbon connector. The two additional connectors contained the D, I and K Busses and the input and output leads to the IKE.

Since 9/97 the external IKE control module was integrated into the display unit creating an integrated component. The CAN bus was also linked to the instrument cluster starting model year 98.

The IKE contains all of the processing electronics for the Instrument Cluster and On-Board Computer.

The Instrument Cluster is merely a display unit and performs no processing. On Board Computer data can be displayed in the MID/BMBT or the matrix display ill the cluster.

Signals that are intended for a component that is on the I/K-BUS must be passed on by the IKE. Also, diagnostic data must be passed through the IKE to the "I" and "K" busses as communication between DIS and control modules takes place.

The IKE incorporates an EEPROM for storing the Central Coding Key (ZCS).
