I drive a 2002 HONDA ACCORD EX. I needed a new battery. The car mechanic replaced my battery with a new battery. B/c of this, the sound system (radio and 6-CD changer) stopped working. There was some error code in the display (I am pretty sure it said "CODE"). It took me several weeks to find my note where I wrote down what the PIN for the sound system is. In the meanwhile, the error code changed from "CODE" to "ErrE" in the display. Okay now I enter the PIN which I finally found. No result. Sound system is still dead and display shows "ErrE". No info about this in the manual, which I consulted. Please help!!! How can I get the sound system working again? I love my Honda but I would be happy if I could listen to music again. Thank you.

 

Take your negative battery cable off for a minute or so, and then put it back on and tighten it up. That should return the radio display to "Code," allowing you to enter the code. If the code is wrong, you're on your way back to ErrE.
