I have the same deck, and the exact same problem.  I do have the manual, but it does not help at all.  It just says that if you get and ER2 message, check the unit power source.  But for my deck I know it is the motor, because you can hear it trying to eject...it clicks loudly a few times before it spits me back onto the radio.  It's cheaper to get a new deck, them pay someone to repair it...I'm getting it done this weekend.
