SOURCE: where is the tcu in a 2002 honda accord

it is the Transmission Control Unit. you have to find the reason why the TCU is flashing the D4 fault code. not replace the unit. have your vehicle scanned for another code. your transmission or transaxle is giving you a warning that something is wrong .

SOURCE: car will not start when hot, D4 light is flashing, car will start

I had a '91 Accord. When the car would get hot, i.e., sitting closed up in the hot sun, the car would not start. Not even turn over. I don't know what the D4 light is. I called John Eagle in Houston where I bought it brand new. The service supervisor said it was probably the main fuel relay. I think that's what he called it (it's been a few years). This relay shuts the gasoline off to the engine when the car gets too hot. It is a safey thing so that the car won't catch on fire, like in the case of an accident. He said to open all the doors and raise the hood so the car can cool off. Sure enough, after about 15 minutes or so, the car would start right up. If I remember correctly, I think the relay is located under the carpet on/near the firewall on the driver's side. Seems like the Honda OEM part was about $80.00. Don't know if this helps or not, but I thought I would throw in my two cent's. Good luck.

SOURCE: d4 light flashing and car wont start 92 honda accord

You more than likely have a problem with the TCU (transmission control unit). It may also be other things. You need to seek professional help before spending money on a TCU that may or may not be the problem. It takes an expert to diagnose this problem.

My 2008 Honda Odyssey's turn signals are not flashing. Can anyone please assist?


The four way flashers and signals are two separate systems and have their own flashers, most are located in or near the fuse or power distribution box

1995 honda accord with sport shift the sport shift light keeps flashing on the dash and when does the car shifts to a lower gear, and when i come to a stop it does not shift down


This is usually fixed by replacing the TCM (transmission control module). This is a very common problem with Hondas and replacing this part almost always fixes this problem.

Transmission screwed??


You will have to give a little bit of time on this one. The over heating coming up through the vents, sounds like your heater core. Now the temp gauge not working may be a sending unit (which one I am not sure there is three of them). The sports light I have never heard of that before. Now the car stalling and not turning back on could be a few things like, clogged or catalitic converter, or crank shaft sensor just to name a couple. The speedometer working only part of the time is usually the speedometer gauge in the dash but if it don't work at all it's probably a snapped speedometer cable or even a loose one.

do you plug it in at night and in cold weather? Sounds like a fuel problem. Check your fuel filter and add conditioner to your fuel. Hope this helps.

1991 HONDA ACCORD 178000 MILES RUNS GREAT LOOKS GOOD. wILL NOT COME OUT OF SPORTS MODE AND CHECK ENGIEN LIGHT WILL NOT GO OFF.. CAN YOU HELP


maybe computer under the passenger side floor board. If the sport light is flashing, then it could be the speed sensor. This link can show you how to check the check engine light on this car: http://troublecodes.net/honda/ You need to find the blue plug and insert a jumper wire, then you need to count the blinks in the led lights, and then compare it to the trouble codes. Carefully pay attention to the blinks, some will be short and others long. Long I think are 10s and shorts are ones. Once you get the code, then scroll to the bottom of the page and you will see the OBD1 codes, that is the one you need. Hope this helps somebody.
