Ок, не буду спорить  я сильно тоже не вникал - исхожу во многом из обще-инженерных представлений |
Вот и я так же. Просто есть некий страх перед нежданчиком в разных ситуациях. Вот кстати отыскал в одном из доков BMW, но опять же это ни о чем не говорит, кроме того что IKE являеться шлюзом:

Bus Gateway
BMW uses the Instrument Cluster or the Instrument Cluster module (IKE) as the connection or bus
gateway between the following four buses.
• D Bus (RXD/TXD)
• I Bus
• K Bus
• CAN bus
NOTE: i Note the following regarding the IKE gateway:
• The IKE control module is mounted on the back of the instrument cluster and is connected to
the cluster with two additional connectors containing the D, I and K buses.
• The IKE holds the processing electronics for the Instrument Cluster and onboard computer.
• Signals sent to a component that is on the I Bus must be passed on by the IKE.
• Diagnostic data must be passed through the IKE to the I and K buses as communication
between a scan tool and I and K control modules takes place.
• The IKE stores the central coding key.
NOTE: i Because of the Instrument Cluster role as the gateway, always check complete Instrument Cluster
warning lights and display messages as well as all gauges for functionality as indicators of proper
bus operation.
z To check bus gateway (IKE) operation:
1. Perform a full instrument check (all gauges, lights, tachometer, and speedometer operation).
2. Connect a scan tool and check for any I, K, or CAN bus faults stored in the IKE.
