I recently went through the process of installing a PA11-NIS and following installation, the CD player decided about 2 minutes later it was having an F0 error. Using guidance from another post in this thread, I elected to disconnect the battery again for 30 seconds and see what happened. Result: the changer goes through all its initialization but still generates F0.

Next, I disconnected the battery again and waited the 30 seconds. After reconnecting and having nothing to lose, I immediately turned the car to ACC mode, began smacking the sides of the player, and to my amazement, caused the error to change from F0 to F3. It did take me a couple of tries to get it to this point.

I rinsed and repeated, and lo and behold; I can play CDs again.

No more F0 or F3 errors.

"Hey Ritchie, I gotta try!"

 

I love it when sheit like that works
