94-97 Honda Accord Computer Removal: ECU/TCU

- เผยแพร่เมื่อ 21 ส.ค. 2024
- NOTE: Some 96-97 Accords may have ECU/TCU combined in a single unit instead of separate units as shown in video.. How to remove/replace ECU (engine control unit) and TCU (transmission control unit) in a 1995 Honda Accord.. Should apply to all 5th generation Accords (94-97).. I personally don't disconnect the battery when removing/installing the ECU and I've never had a problem.. But it's probably a smart thing to do.. That way you fully restore power to the ECU all at once instead of partially restoring as you connect each of the 3 harnesses..

Clear and to the point! This is how all instructional videos should be. Excellent!
Dude this video is great. I saw your comment about putting the ECU in the freezer to diagnose it and that helped immensely. I don’t recall if it was also said in the video, if it is I apologize, but the comment mentioning putting the ECU in the freezer should be put up in the description and be screamed from the rooftops. After days of researching about crank no start issue, that was the first I saw of testing the ECU by putting it in the freezer. Thanks again dude 👊🏼👊🏼👊🏼
Glad the video helped.. I have a separate video related to the freezer no start tip:

I have the factory service manual for my 96 Accord with 4cyl sohc automatic. I couldn't find anything about where the damned computer was located, so mucho gracias for your explanatory video! One big difference is that my car did not come with the transmission control unit, so hopefully the tranny problem is in the computer. I went for the computer after going through a bunch of reman alternators having similar failure issues after 20-50 miles.
Clear & concise. Thank you. 💪
You're welcome.. Glad to have helped..
good video guy keep doing what u do u explained everything very well
Thanks.. Hope it helped..
Awesome Video. Why are u called the peanut butter man.
1984.. i was a brand new rookie fireman.. money was tight.. always had peanut butter and a loaf of white bread in my kitchen locker.. someone called me PBM one day and that was it.. name stuck for 35yrs..
@@tongo117 I fuckin love it haha
Thanks dude. Your vid helps me. 95 accord ex no start in damp conditions.
Glad to help.. Thanks for reply..
Hello,
What a great video. You get straight to the point of rem. rpl of the TCM. My 1996 Honda Accord had a ABS light go on and stay on.
Shortly there after the Check engine light came on. Diagnosed to the TCM.
Do you happen to know if the TCM is connected to the ABS system?
Haven't had a moment to remove the carpet underneath the passenger side to look to see if the ECU/ECM and the TCU/TCM were placed into a single unit.
If this is the situation for my Honda, what are your recommendations of purchasing a new single unit? Where would you recommend I purchase one from?
I'm not opposed to purchasing a refurbished one.
Thank-you
Up to this point I've gotten by with junkyard ECU/ECM's for my 95 but good ones are getting harder to find.. I've had this site saved for several years in the event I need a refurbished one.. Free shipping, lifetime warranty.. No idea if they are good/bad..store.allcomputerresources.com/searchresults.html?query=1996+Honda+Accord

Hello,
I was able to open up the passenger side compartment and confirm that I just have the one ECU/ECM and the TCU/TCM single unit.
The single unit has a date - March 26, 1997. The bar code reads - 37820-P0H-L52 887-344355 IPT.
Do you still recommend I order an ECU/ECM from the link you provided which are primarily a 1996 unit?
Thank-you
If you click that link there's a toll free number on the top right corner of that page.. I would call them first and tell them your situation before ordering anything.. They will want the bar code number so have that ready.. Good Luck!!
@@tongo117 Will do!! Thanks for all of your help.
Hello,
Called All Computer Resources, they asked for my VIN number as well as the ECU number and was able to place an order for a new computer.
Really great resource for sure.
Many thanks for your expertise on your video. Was quoted an estimate from a Transmission company near me at $1240.00 to replace the TCM.
Saving all sorts of money!
Thanks this was super helpful!
Glad to help.. Thanks for reply..
Thanks amego grengo
Thanks for the video! Wondering if you had issues with your ECM ? I have a 96 Accord DX with the F22B2. That keeps stalling randomly. The main relay had been replaced, as well as the ignition switch in the last year. I have spark, and fuel pressure when this happens. I suspect no injector pulse is causing the problem. However it always restarts eventually. Usually 10-20 minutes after. I looked at the solder joints in the ECM and they all look good. Not sure if you've seen something similar ? Though mine is OBDII, not sure if yours is OBD I do to the year difference.
Thanks
No issues with the ECM at this time.. I had a front passenger water leak and took everything out to dry out carpet.. I have had 2 ECM issues in the past though.. Both solved with ECM (salvage yard) replacements.. First was no start when interior of car was hot.. To diagnose, I took ECM out of hot car (heat expands solder joints to expose cracks) and placed it in fridge for 1 hour.. Plugged the cold ECM back in (same hot interior) and engine started/ran fine.. Second issue initially led me to believe I had a transmission problem.. RPM's would surge and transmission felt as though it was slipping.. I had stockpiled a few ECM's at that point and swapped one out just to see if that was the problem.. Problem went away.. Put the old ECM back in to confirm issue, problem returned.. Faulty barometric pressure sensor in ECM?? Don't really know.. I keep an eye on two salvage yards where I live for automatic 94-97 Accords with non Vtec engines.. Specifically to check for ECM's that match mine.. I like having spare(s).. Good Luck with your issues..
Clean ur egr port and the intake ports they full of carbon easy by removing the fuel injector rail
Thank you!!!
Disculpe tengo un honda accord 97 y la trae abajo del aciento una nadamas no trae otra por otra parte?
Is mine under the radio? Or is it the o e under the radio on the hump against the firewall IN THE CENTER OF THE CAR NOT THE PASSENGER SIDE
On the 1995 Accord, do you have to reprogram the replacement ecu or is it p&p?
Just plug it in.. No need to reprogram.. At least for mine.. Not sure if that's true for all 95's..
How do you thread the black and yellow wires of the ecu back through the firewall to the intake manifold? I had to cut them to get the intake off and rebuild the engine?
not sure.. never had that issue..
@@tongo117 Nuts! Thanks anyway, man. Guess I'll just have to tear the dash apart to get to it. Such is life.
On 1994-1995 Honda Accords does the A01 or A02 on the end of the TCM number mean anything significant or is it just a revision number? I'm wanting to check before I get a transmission for my 1994 Honda Accord LX wagon so I can make sure I get the right TCM or can reuse the one already installed.
Got this info from a site explaining ECM numbers.. Not sure if it applies to TCM's also..
"The last 3 characters are broken down into 3 parts. "A" generally is used for US ECUs. "G" is European, and "J" is Japanese. There are other versions of this, but you get the idea. The second digit "0" typically means manual transmission, where a "5" means automatic transmission, and the last digit "1" is the version number."

Please help me, my ECU finish in Y02, can I use another that finish in A02? Cause I think only changes the country where it was make, based on the information you put below
Based on the information on that site you may be correct.. But I don't know for sure..
My tcm is not located there and i have a 96 accord 😢
On my 1996 there was only 1 unit which comparing it to yours looks like the ECU/ECM and had 4 plugs instead of 3. For the 1996 were the ECU/ECM and the TCU/TCM put into a single unit?
I guess I need to change the title of video cause yes, it appears your 96 has a single unit.. Research found this info.. "The stock 96-97 Accord with automatic transmission uses a single PCM/ECU to control both the engine and auto transmission"
@@tongo117 yeah I found this out a bit after I left the comment.
Where is the ECU for a 91-92 Accord??
I need a new ECU on my 94 5 speed. Can i use a ECU that came off a Automatic transmission? Or i need to find one that come off a Manual Transmission?
The computer ID numbers have to match old vs new.. Automatic will have different computer.. Gotta find a 5 speed manual and match the numbers.. This may help:

Excuse me sir i was wondering if you had to disconnect the battery and let it sit for 15 min before installing the new ECU
Good question.. I personally don't disconnect the battery when removing/installing the ECU and I've never had a problem.. But it's probably a smart thing to do.. That way you fully restore power to the ECU all at once instead of partially restoring as you connect each of the 3 harnesses..
@@tongo117 ok i was justcwondering because i seen a different video and it said u may have to flash it or calibrate it but my friend said i can just do the replacement without that
1:23 "fold it down". I've got this far, and it's not folding down. Something is pulling and straining and feels like it will break if I force it down anymore. Any tricks for this part?
after removing the four 10mm nuts that hold the kick-plate down you have to pull it towards you a little until it clears the four threaded studs.. once you do that, you should be able to pull the top towards you and lay it down flat like i do in the vid.. the top may catch on the bottom of the glove box but you just work it past that.. then the only thing(s) attached should be the wiring harnesses..
@@tongo117 the problem was I didn't pull the carpet back far enough and it was getting caught on it. Just fixed it now
Is it possible to gearbox remap a '00 Accord?
Changed the air intake and exhaust system, now the rpm's running too high on me
I have no idea, sorry
Do you know if the Automatic Transmission Control Unit needs to be programmed or is it plug and play?
on my 95 Accord it's plug and play.. not sure about newer models..
@@tongo117 Okay good. Mines a 95 too.
Will this tcu work on a 92 accord?
ok!
if you have a manual do you still have a TSU?
I don't think so cause you don't have an automatic transmission.. And your ECU may only have 2 harnesses that snap into it instead of 3 like mine.. No communication needed between ECU/TCU on yours so fewer wires.. honda-tech.com/forums/honda-accord-1990-2002-2/tcu-ecu-3209015/
can u help with a 94 Honda accord automatic engine computer unit
help you how?
Can you send me an 96 vtec 2.2 ecu
don't have one.. my accord is a 95 non vtec
What numbers do I have to match on the replacement ecu?
The numbers shown at 4:49 (top) and 4:52 (side)..
My car is a 1996 Honda accord lx 2.2l non vtech with automatic transmission any idea wich ECU should I get?
You either have to get the numbers off the ECU that you have now or a Honda dealership may be able to tell you which ECU you need if you call and give them your VIN..
What about a 98 where is it located
I don't know from experience but apparently you should find yours behind the center of the dash below the radio.. www.2carpros.com/questions/honda-accord-1998-honda-accord-ecu
I have a 1999 honda accord v6 3.0l with a B7XA trans and guess what that is NOT where the cpu is located wish TH-cam allowed pics instead of text comments
I don't know from experience but based on the info in this link yours is located behind the radio.. Shown at the ;57 mark in the video.. www.pullapart.com/video-library/videos/how-to-pull-a-honda-computer-honda-accord-1997-2002/
Where is the srs unit located?!
I've never had an issue with SRS so I don't know where sensor unit is located.. But there's a diagram in this repair forum thread that may help.. Scroll down a little to a post by redbull 1.. He has a thumbnail attached with diagram..www.hondaaccordforum.com/forum/general-tech-help-7/srs-cel-obd-1-stuff-any-thoughts-suggestions-50285/
red bull 1's second post has the SRS diagram..
What about for 99 Honda accord ex
I believe yours is located behind/below the center of the dash.. Not on floorboard like my 95 accord.. There's a diagram in this link.. www.2carpros.com/questions/honda-accord-1999-honda-accord-location-of-ecu
I switch it but now it only cranks but doesn’t start
Can i put one from an automatic honda mine is manual?
I doubt that would work.. The part number on the new ECU needs to match the part number on the old ECU.. www.hondata.com/tech-ecu-identification
