At approximately 2 years ago I had the catalytic converter changed @ about 190000 miles. Took it to be inspected today and it failed with code p0420 & p0430 Catalyst System Efficiency Below Threshold (bank1 & bank2). Is there anything else I can do or check to fix this other than replace the converter again. Also I dont have a code but the abs lite and the brake lite illuminate together at the same time. Please help?

Are you sure your scanner can read ABS codes? If it can, check simple things such as brake fluid level, park brake switch.

As far as the converter, chances are it needs replaced again. Since it is only 2 years old and you only put 40K miles on it, it should still be under warranty. Most any converter that I have seen come with a minimum 5 year or 50K mile warranty.
