There are over 40 different malfunctions that can cause an error 99 on a Canon 40D. The 2 that account for over 95% of the error 99's are either a bad shutter mechanism or a bad mirror driving motor. It takes special diagnostic software to determine the exact cause. Otherwise, a repairer just has to start replacing parts until the problem goes away.
