Honda Repair: honda, fuse box, blade style

Question
I have a honda accord 4 cyclinder  and I need to reset the code , this is a used car no manual help please

Answer
Vonna, not sure what code? Disconnect Negative (-) battery terminal for 30 seconds to a minute. Or under the hood, open fuse box, remove blade style fuse for hazard. Should be a red (10) amp or blue (15) amp. Leave unplugged for 30 seconds to a minute. Whichever you do should reset computer, ECU. Try the Hazard switch first just in case you have a stock stereo and that way you won't need to re-enter the code. If this doesn't fix your problem this means the ECU is recording an error that needs attention.
