E46 Cluster K-BUS Fault

[venceslau]

Hi all, I have E46 Cluster with KBUS fault code and KBUS functions are not working.

I tried replacing the elmos chip and compared the chip voltages at each pin from a known working unit and everything looks ok.

The cluster is from a 2003 330Ci with the revised cluster.

All help appreciated. Thanks in advance

Elmos chip I swapped in was also bad. Put third donor elmos chip in and everything is back to good working order.
