1999 Honda Accord 4 cyl Automatic 100000 miles

I just bought a 1999 Honda Accord and its in great condition. It has 100,000 miles on it and it had one owner. The car fax shows the car was always brought to a honda dealer for all maintenance for the entire 10 years. The first day I got the car after driving for a few miles the D4 light starting flashing and there was a clicking noise that sounded like the signal. Also at the same time I had the heat on and that light was flashing as well. And the rpm arrow. It shut off then happened again after a few minutes. I looked in the manual and it said when the D4 light flashes its a transmission problem. The car drives perfectly fine though. I brought it to get a diagonistics check and no codes came up. I went twice and no codes. The past two days I have driven the car there was nothing flashing and nothing happened at all out of the ordinary. I dont know what to do! I only have a 30 day warranty on the engine and transmission. It took me a while to save for this car. Ugh I cant believe this is happening, any advice would be great :(

Hi ammre513,

You are correct about the D4 flashing indicating some fault however if the codes are not stored, then it would be almost impossible to diagnose the problem.

I would suggest testing the computer memory to see if it works correctly, just so that if the problem happens again, it would be recorded. Check the backup fuse.

There was a recall for the ignition switch which could cause power supply faults and it might be related to the problems described. Check out with the dealer if your vehicle ignition swith had been replaced and if the TSB is applicable for your vehicle.
