Just replaced bulb on my 2002 Accord EX. Simple to do.
1. Lift up the trim piece around clock; just slide a putty knife under and lift.
2. Take out assembly and look on underside for small gray bulb base ( about 3/16 dia.). It helps if you have the new one to compare.
3. Use small blade screwdriver in slot and rotate counterclockwise to remove. You may have to shake it to get out.
4. Examine the new bulb to find the slots that DO NOT have wires. Put bulb into socket and rotate clockwise with screwdriver in proper slot.
That's it; you now are there.

No-one is ever particularly happy to here this, but this is the way it is; we do have to keep in mind that the original idea of codes on radios was to prevent people who steal them from being able to use them.

So, if an audio unit with theft protection is disconnected from electrical power, you must enter a unique code number into the unit or it will not work. This code and the audio unit’s serial number are listed on the anti-theft ID card that comes with the vehicle. If this card is lost, you must obtain the audio unit serial number in order to get the radio code (some people say that they have found the code on a sticker inside the glove compartment, but I wouldn’t count on that). Some newer vehicles allow you to retrieve the audio unit serial number electronically from the radio. Refer to your owner’s manual for the specific procedure (the following usually will work: Turn the radio off. Push the preset 1, preset 6, and power buttons at the same time, then quickly release. The serial number will come up in two sets of numbers.)
Some older vehicles (model year 2003 and older) require a visit to the dealer in order to retrieve the audio unit serial number (or you can remove the unit and get the serial number from the back of the radio). Once you have the audio unit serial number, you can call Auto Customer Service at (800) 999-1009 or have the dealer look up the radio code.

Here is the URL for the Honda Owner page. If you register (no charge) you are able to get radio codes using the VIN number of your car, the serial number of your radio, and the Phone Number and Zip Code that you give them when you register.

Describe what do you do if your D4 light is on a 92 honda accord ex and wont let you take off fast Problem

SOURCE: check engine light is on,

Could be as simple as a loose gas cap or cap seal or a bad o2 sensor. A falty cat. converter will also cause the check engine light to come on. Either way, you need to go either to a dealer or some auto parts stores will plug in the dioegnostic sensor and can tell what is wrong. your gas milage will suffer until you get this fixed. Your engine computer uses the inputs from your o2 sensers to adjust the fuel air mixture of the engine for optimum engine performance.
