SOURCE: stereo error code
The code for the radio needs to be input.
the radio must have been disconnected from the battery.
look for the code on a card in the glove box. if no card, then u have to pull the stereo out and get the serial # to the dealership.

SOURCE: what is the code?
Most hondas have the code on the vehicle itself for resetting the code once the battery has been disconected or radio removed. Try pulling the glove box out and looking on the inside of the cavity. You should not need a code to remove the radio the alarm should not go off, it is the installation. The radio will not work with any other --vehicle without your specific code, good thieves know this and would rather steal the whole car. "Especially the Honda Accord. Have one in the garage and a 2005 Pilot.

ok your radio displays ERR , OK 3 options let it sit for an hour turned on , to reture to CODE display , or pull the radio fuse out for a minute and put it back in , returning to the CODE display , or disconnect the battery for a minute , returning to the CODE display . you got the ERR display because the code was wrong or not entered correctly , make your choice of getting the radio back to the CODE display by 1 of those 3 choices , while the radio displays CODE , use the preset buttons , if the first number of your code is 4 , then press the #1 preset button 4 time , when the first number has been input , put the 2nd number in by pressing the #2 prest button , if 2nd number of code is 8 , press the # 2 preset button 8 times till the # 8 is displayed , and so on . you see where this is giong ? when you have entered all the numbers correctly you will have you radio back . when you say you have the radio code , good luck ! were rooting for ya .

Hey I had the same code and I have a 2000 honda civic lx. My cousin
works at honda and drives a '96 honda civic and he has had that code
before on his car as well.
First thing he came up with was that the catalytic converter was cracked. We checked mines, and lo and behold, that's what it was.
Look under your hood, and there should be a catalytic converter with a sensor sticking out of it. It is connected to the exhaust manifold and the sensor sticks out of the heat shield. Around the sensor, look for a crack. If there's a crack, that's your problem.

I have an '06 Honda Civic. The most common places where the code is found is on the left side of the glove box, in the trunk somewhere along the gasket or underneath where the speakers are, under the fuse box panel, under the ashtray and sometimes under center console lid. I happen to find my in the left side of the glove compartment. The first five digits are the code and under that, you should see and 11 digit code which is your radio serial. So once you have the code if you haven't already, turn on the radio. It will ask you for the code and you punch it in using the number on the buttons you use to change your radio stations. As you punch in numbers "CODE" will start to fill in. Just like the asterisks used in passwords. If you punch it incorrectly, it will say "error 1" or something to that effect. Do not push anything else, just start over by punch in the first number of the code and then the rest. Be careful, if you attempt too many times, the radio will lock itself and you will need to leave the radio on for an hour for it to reset itself. When successful done, the radio will turn back on to the last station you were last on. Hope that helps.
