from the error code you've described, the error code list says its a network interface problem. although , its actually 0002.
error code listI don't think I've read about the 3RLOD being related to that though.
are ya sure it wasn't 0102? check it again, and if it is related to network interface problem then what you're doing(replacing clamps) isn't going to help anyways.
and, you should have posted in the hardware forum, you'd probably get more help that way.
