I really do not understand your question. Are you referring to radio codes, or are you referring to OBD codes? Please clarify.
I have a 92 Honda accord with anti theft radio that needs a code when battery is disconnected. My code is 34444 if you have tried several codes that did not work you might need to disconnect your battery and reconnect battery again then try the code.
Push the power button on the stereo then enter the code

There are only 6 service codes for the Honda Accord. Never heard of service code 7.
Disconnect your battery cable for a bit and then reconnect.
Try disconnecting the battery for 20 minutes then reconnect.
Remove the negative battery terminal (-) for about 15 minutes and most codes will reset.
Disconnect the negative battery cable for five minutes and this should clear the codes. If not, you will need an OBD 2 scanner to reset the code.
