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.

Check the TCU or TCM located passenger side floor area.
when you take it apart it will have bad soilder connection on the left side. It will need to be replaced.
