SQL2k5 SP2 Db Integrity Maintenance Plan Fails

I created a user db integrity maintenance task. The created job runs once a week. It fails. How do you tell at what point is fails? The history log is not specific about where things go off the rails.

The job errors as follows -
Execution of job "User Integrity check subplan_1 failed. See history log for details

If I run the sql in a query window it goes right through - error free.
