D4 light flashing and car wont start 92 honda accord

This is your transmission control unit telling you there is a problem. I have another post here (http://www.fixya.com/cars/t5554380-92_honda_accord_d4_light_flashing) with details on how to diagnose. This link says "flashing D4 light" but the issues it the same. 90-91 accords have flashing S lights for TCU errors, and 92-93 have flashing D4 lights.

The Blinking D4 light means that the transmission computer needs to be diagnosed, because there is a malfunction.

Cheap fix, try Lucas transmission fix fluid. (internal rubber hardens over time)

What solenoid did you replace? Disconnecting the negative battery cable will reset the flashing light, however, if it goes back on, or fails to reset, you still have an issue to correct with the accord.

i have a 92' honda accord lx, it has a problem of the D4 light flashing and the car wouldnt start, but i could wait a few minutes and try again and it would start.

D4 is slipping and not engaging. This means you need a transmission. you're losing a gear

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

why does the light in d4 flash when drivinh???

d4 is flashing as a trouble code for the automatic transmission... i would say without research that it is a code for a transmission solenoid. maybe while washing the car some water got in and caused a short...these solenoids are usually weatherproof....you could try disconnscting the battery for 30 secs..to clear the trouble code and then start the car. remember you may lose your preset info!

on my 95 accord my d4 light used to flash after driving for for an hour or 2 then the speedo would do strange things.so i changed the speed sensor relay [located on the gearbox] and solved the problem.
