Default ECU "cannot communicate"

Hey everyone, I'm new to this hood. Got a quick question, trying to get my 99 Civic Si smogged, and I'm getting a "Cannot Communicate" error.

My ECU isn't stock.

specs: (OBD2 B 858 JDM PCT-J11 97-01 Civic EK9 CTR KS, no PA, no immo )

Laymans terms, it's a type R ECU. To my understanding there should be no conversion problems? Same harness, both OBD-II...anyone have any ideas? I'm lost, and the dudes at the smog place are clueless. Thanks ahead of time!

Change it back to the stock one or another usdm one and your set.

In Laymans terms, the take out the jdm one when you smog.

. . . Hey I got an identical problem, here goes:

First of all: Hello HONDA-DUDES ! !

I just signed up here, so I pretty much know NOTHING

about whats going on here.

I hope we can have some fun CAR FUN . . . Let the fun begin ! ! !

. . . anyway this is why I am here:

I just bought an old 1997 Honda Civic automatic

in good condition for 500 bucks.

Its not stolen, and I can register it any time, I have checked.

I want to make this baby spin for my gf, is why . . .

If it spins, she may spin too and all for me

First of all I need to get it started, I never thought that would be an issue!

It seems this 1997 old Civic got an IMMO,

damn! Well wonderful, I love teasy stuff ! ! !

The dealer offered me a key for 200 bucks,

and I said NO thanks, I said WHAT ? ? ?

200 BUCKS FOR A KEY ? ? ? ?

I did not tell him that I am an electrical engineer,

and I kind of laughed big time at him,

did not show my laff however

I just laffed cuz I think I got myself a GOOD DEAL . . mmm but did I ? !

I am not a car expert, I work with analog-2-digital converters for satellites.

I wonder how the satelitte-name came about . . . mmm

. . . Well anyway now about one day later,

I realize that this old 1997 Honda baby "PROBABLY GOT" has an IMMO,

because I cannot start it with a standard-key,

and I cannot start it either doing the basic ignition trick,

pulling out the wires and ignit it.

IF it has an IMMO, I simply want to remove the IMMO,

and put in my own "anti-theft" !

As an electrical engineer I do NOT trust old electronics NEVER EVER.

I know how badly they can fail, and the less electronics U got in UR CAR, THE BETTER ! ! !

I know how badly electronics can fail, worse scenario:

U found the love of Ur life and ur car fails to start!

Not a good start, dude

I found this link on the internet, showing what the IMMO looks like,

but I am not sure I can trust this link since its

a company in Lithuania, Eastern Europe!

The link is: http://www.codecard.lt/files/Honda%2...20emulator.pdf

Just in case u dudes dont want to click on any link from Lithuania,

I will upload the IMMO-photo

here in an album named "IMMO-Gonna CRACK U"

So what do u Honda dudes say, is that how the IMMO look ?

And how the hell do I locate it ? Where the heck is the ECU-box ?

I do not think this OLD baby has an ECU-box ? cannot find it anywhere!

Thanks in advance!

Depending what scanner they are using, it may be because they are entering the VIN for your car and it is not matching with the ECU. The Honda PGM will not 'connect' with the ECU if the VIN and the ECU don't match up...

WTF is this crap? start your own thread, single space your posts preferably. You don't have an immobilizer. No '96 - '00 US/Canadian civics did, they don't take a special key. European models did however have an immobilizer. ECU is behind the passenger's side kick panel.

Actually, I think most of 94EG8's comments are helpful.


OP, do you have a no-crank or no-start problem?

It is cranking because it does not get the signal from the chip-key to start.

I do not have the chip-key that connects with the IMMO.

And yessss its an european model . . .

Thanks in advance!

If its a Euro ECU you pretty screwed IIRC, they aren't like the USDM '00 - '01 Integra ECUs that you can simply remove the immobilizer and have the ECU work (albeit with a constant CEL) you could also solder a dummy unit into these ECUs to remove the CEL. The euro models however use a different immobilizer and I don't know of any way around it.

I hope I am not screwed ! !

A dude in another thread wrote this:

"ok well there's a big chip in the ecu that you can remove and you'll be good. it will throw a code but other than that you'll be fine. The information doesn't get tossed around much because it's obviously beating the system but a lot of people who get obd2 type r swaps want to retain the ecu and that's the only way of doing it. i believe you'll have to desolder the chip. it's a really tall one."

. . . I hope you did not forget that we are talking 1997 Honda Civic and not "Integra".

As always THANKS IN ADVANCE

No I didn't forget, my point is the Integra ECUs you can do exactly what you just said, remove the immobilizer and the ECU will work, but have a constant CEL, Euro ECUs don't work that way, without the red learning key your ECU is paperweight.

I have posted 2 photos in my gallery of the IMMO.

Is this how the BEAST LOL actually looks like ?

your pics don't work, again your ECU is a paperweight, You can however use a USDM ECU which is not immobilizer equipped, you may need to add in sensors that may or may not be missing from a European civic.


Hmm, it appears Katman is able to remove immobilizers from EDM ECUs and replace them with a dummy unit now, PM him for details.
