machine will do random c9000 code turn off and on code clears, machine has been out for about a year and it has 330 c-9000 codes, any help out there? things i have changed, engine control board, dimms, scanner control board help

You hit everything except the most logical: what about the DP controller, or the harness?

there's a service bulletin for this..

u have to change 3 parts..the base of the dp,the wire interface ( wire that from dp)and the rear cover...

ok

Any chance I could get the bulletin number on this? I'm having one that's doing the same thing... Thanks!

I have a machine throwing this code constantly. I changed the DP harness, main PCB and Engine Board, still not working. I can't get QA 9119 on the Knowledge Base to open, can anyone provide the details on the fix for this issue? Thanks.

tech pete is right... ive done this about 5-6 times and the 9000 code hasn't come back on any of the machines. the service bulletin # is:
SB#8729/3K5-0009
from feb '09.

there is also a QA for this but it cover only the wire interface and not the covers...
QA8425

Thank You.
