The older panasonic decks in the integras and cls will display different error messages than a newer pioneer like the one in your civic. Look in your owners manual to see what your error message means, it could actually be something as simple as it needing to be cleaned.

In the Integras, the spindle motor gets weak and cannot start the cd anymore, so it displays the "PE-0" error message and acura dosent do a damn thing about it, they'll just tell you they cant replicate the problem.
