I am getting an error e code for my stereo after replacing my battery.

Here you haven't mention your model name, Go to the given link which is online store known as reliable, they have repair manuals, I am sure you will get the solution Best Manuals

Get the Code from Volvo, remove your battery cables for Half an Hour, replace cables. turn on stereo and enter the anti-theft code.

Dannielle, if the previous owner installed the radio, it must have worked. It is possible that error code may have no connection with the replaced radio which may work when connected to battery. It depends on the complexity of the new radio. If it is simple, s/b ok.

error code 12 is "communications error" Ford manual says replace radio. You may remove the radio open it and check for bulging capacitors, go directly to manufacturer webpage for a replacement capacitor.

Unfortunately 90% of the time when you get error codes from the CD player/changer it means that there is a mechanical failure in the CD player/changer unit itself and it usually requires CD player/changer rebuild or replacement...
First make sure you have entered the correct anti-theft code. If battery power has been disconnected recently than the stereo display will read CODE if the incorrect anti-theft code is entered the display will read ERR1 thru ERR3. If this is the case you'll have to get the correct anti-theft code. Note; If you enter the incorrect code three times the stereo locks up. Disconnect the battery for more than 30 seconds and then retry.
FYI;Never use adhesive labels or protective disc covers on recordable CD's. Recordable CD's are actually thicker than pre-recorded CD's. Automotive players and changers use rollers to draw the disc into the unit. The added thickness of an adhesive label or protective disc cover may cause the disc to jam. Also CD players and changers are exposed to high temperatures inside the vehicle. High temp will cause the labels adhesive to soften which may cause the labels edges to curl or cause it to bubble. Either one may cause the disc to jam and cause the player to display error codes E-01 thru E-07. If the player can not be disassembled and have the discs removed successfully than it will have to be replaced. -hope this helps.

I just changed the battery in my 08 accord same thing there is a code on the left side of glove box.type that code in using the preset numbers it will be on white sticker

Try disconnecting the battery for a few minutes. No guarantees but this might reset it. If it contunues then I really do not know what to tell you. Seems a lot of these are doing the same things. Easier to replace it with the stereo of your choice

The 4 digit code is to unlock the stereo if the stereo is asking for the code.
If your stereo is working fine then just ignore it but keep the code safe, if your battery ever gets disconected or you remove stereo and put it back in then you will need the code to unlock it again.

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.

I won a 2004 Honda Civic.
I had a bad battery and my car would not start. I had someone jump start it and it now has a new battery. The car runs fine but the stereo will not play am/fm or CD's. Regardless of what I do I get an "Error E code"

Please help.
