Take it to the garage or get some one with a diagnostic computer to check. Its one of the transmission pressure switch.

The D4 light blinking indicates there is a diagnostic trouble code stored.When a malfunction occurs,the vehicle computer records the code and stores it,then flashes the D4 light to let you KNOW there is a problem.On pre OBD 2 Honda vehicles,1995 and back,Hondas are manual code read,which means you do NOT hook up a scan tool as there is no scan port.The passenger side front kick panel is removed,and a blue 2 wire connector located.Use a jumper wire to short out the connector,then turn the ignition key on,with engine off,not running.This throws the computer into self diagnostic mode,and the D4 or "s" light will flash a series of flashes.The flashes have to be counted,and written down.For example,2 flashes followed by 4 flashes would be a code 24.The code is then looked up with reference material for a description and diagnostic route.Every diagnostic trouble code,has a diagnostic route,for repairing the problem.Again,this informtion,the diagnostic route,is available in reference material from pay sources like All Data Online.After the repair is made,the battery is disconnected to clear the code.Good luck.

D4 light on no matter what gear i'm in. 95 Honda Accord LX 4-cylinder. Already replaced solinoid, speedometer, fan,


The D4 light is coming on to tell you that there is one or more fault codes set in your transmission control module. The only way to retrieve codes on the 1995 models is to read "Flash Codes" output by the D4 light. (See instructions below)

RETRIEVING FLASH CODES USING THE D4 LIGHT
If fault codes are present, the D4 light will "blink" when the ignition is turned to the RUN position and will remain on at all times when the engine is running.
To retrieve the flash codes, turn the ignition switch off.
Install a jumper wire between the service check connector terminals.
The service check connector is a gray, 2-pin connector located on the PCM/TCM cover under the passenger side of the instrument panel. (See picture below)

CAUTION: DO NOT use the 3-pin located next to the service check connector.

Installing the jumper will place the PCM/TCM in diagnostic test mode.
Turn the ignition to the RUN position. Codes will be output by blinking the D4 light.
Note the number of blinks from the D4 light. A short blink indicates a single digit flash code. A long blink equals 10 short blinks. For instance one short blink indicates code 1. One long blink and four short blinks indicates code 14. If there is more than one fault code, they will be output one at a time from the lowest numbered code to the highest numbered code. It is recommended that you read the code or codes several times to make sure that you are reading it correctly.

Once you have retrieved the fault code(s) re-post your question and include the information for what codes you have and someone can then help you locate the cause of the problem.

Check engine lioght is on and d4 light is blinking n when u step on the gas on d4 it doesnt wanna go???? wats wrong wit it


There are many other things that cause the D4 to flash. The D4 light turning off is similar to the CEL turning on. Some codes cause the light to blink, some turn it off. There's an error code stored, pull it and start from there.

Check this DIY: Diagnosis: Pulling Codes

Definitely pull all the codes and let us know what you find. Once we know what the codes are then we can help you troubleshoot the issue/s. Alot owners talk about VSS (Vehicle Speed Sensor) but the VSS may or may not be part of the issue but per your description it may sound like a main relay to a tranny issue.

Keep us updated.

The D4 light keeps blinking and when this happens the trainny doesnt shift right. I have diconnected the battery, this did work, but did it again after about 3 times driving it.


When the shift lever is in Park, is the D4 light on, or blinking? If the D4 light is on steady, while the shift lever is in Park, chances are your transmission computer has taken a dump on you. If the D4 light is blinking while the shift lever is in Park, the computer has stored a code, that will give you some idea where to look for the problem. Here is a link describing how to retrieve the codes. Good luck.

92 honda accord lx D4 flashes


you have a transmission fault the D4 light blinks to tell you that there is a transmission problem when the light is blinking the transmission computer put the transmission into limp home mode so it will not shift normally and you should try not to drive it very far when it gets to this stage you need to have the transmission codes check to pin point the problem
