You just need some common sense and diagnosis.

Take it to a big box parts store chain, get the codes read. Get the actual code numbers, not their description or parts cannon list. Look up your own info on the code(s) you have.

THEY can't read codes either? Big problem. Read on....

If someone did a timing belt job (or any other work) and left the alternator bolts loose, that can FRY the PCM. That can cause no communication, among a host of other problems.
Look up Honda Service News, August 2004.


The radio says ERR because the wrong unlock code has been entered. Disconnect the battery and retry the correct code. Search for radio code related threads here and READ how to get your code. Don't bother begging for it.
