TruClient Error Logging

How can you enable error logging when executing a TruCient script via PC?  We are executing a TruClient and when execution is done we see the number of HTTP reponse codes (20x,40x, 50x, 30x) but we can not determine the error message when we get HTTP response codes 40x, and 50x.  Is there a way to capture the exact error message and in which object it occurs if the error code was return by, lets say an image within the page that was not found?
