Good news Brave Heart people of this forum!

After days and days of reseraches and hundreds of virus, softwares that does not work at all and many wrong information, I got the solution for that, it is the first step into deconding and finding exactly what we are looking for, remember?

We need:

#1 Coolant temperature "id code" and data for coolant temperature gauge
#2 External display temperature "id code" and data
#3 Oil life display "id code" and data.

With this video, it shows that it is possible to decode the messages sent on can bus network, from can bus signal.

Now the next step will be to find out the "id codes" to can bus logic input and the "databytes variation" that in this case will be necessary to light up the coolant temperature on bar-graph, oil life and external temperature display.

I found this software, but I believe it will have some free software in order for we decode the can bus signal in a honda s2000 2006+ can bus interface system.

Also, once based in this software I will be able to create a software that will do the exactly job we need using only our "notebook soundcard" or if it needs a high definition "sound card" then we can order a "pcmcia" high performance sound card and scan, decode the signals one by one.

I am sure it was a long road of knifes, I am still bleeding my feets, now lets move ahead next step.

I found with precision that the white black strip, "b8" is the can bus network wire!!!!

perseverance

awesome, keep up the good work!

thats unique

Eagle_Phoenix

Well, I thought also, any one here got any datalogg generated for this "ecu"? or I mean the flash eprom file or any data related to this ecu? once I got it also I can debbug the content and search for relevant information, any ideas???

Please, the canbus circuit is done, what i must discuss here is the software, the data that will be "flashed" into the k-line master!!!!

THIS IS THE DATA I NEED, BEAR IN MIND THAT THIS DATA IS ANY DATA FOUND ON INTERNET, I NEED TO FIND THE "ID CODE" AND DATA FRAME FOR COOLANT TEMP CLUSTER, OIL LIFE AND EXTERNAL TEMPERATURE.

I got some downloads here, lets see if I can get the info I am desperate looking for.

POOOWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW

NOW THAT SOME "GREEDY" PEOPLE DONT WANT TO SHARE INFORMATION REGARDING MY "SINGLE" AND SECRET PROJECT, FRIES-FRIES DOES NOT HELP, EAGLE BRING FROM HEAVENS.

HERE IS THE DIAGRAM OF ECT CONVERTER ON PREVIOUS HONDA CARS, I GOT FROM HEAVENS!!!!!

BUT STILL HAVENT FOUND .... WHAT I AM LOOKING FOR!!!!! (IT SOUNDS THAT U2 MUSIC).

KKKKKKKKKKKKKKKKKKKKKKKKKKK

I was testing the battery warning light and some other stuff and it seems that it is on "lin" tecnology .... I will test better to see if there is not any burnt bulb on cluster, but it seems that "even some lights on this cluster works on "can bus data frame id code", then it is complicating day by day more this cluster, but when Eagle Girardi sees a hole in the way, Eagle Girardi looks with anger face and the hole run away from his front!!!!

Honda Technicians used the can high to a speed of what I believe Class "C" 1mbps on CAN 2.0 and mixed the "LIN" together with some other datas on car, for exemple the "alternator overcharge", if it is not charging then the signal message will be sent to cluster to make the "battery light be lit" as there there is no charge-load on alternator.

High bean also is on "LIN" LOCAL INTERCONNECT NETWORK, on this honda s2000 2006+, everything goes into the data frames.

Maybe I may be wrong .... maybe they sold me the cluster with sockets and wires from another model!!!!! MODEL 2005 MAYBE GOSHHHHHHHH

this is ALOT of good info in here but its all way over my head.

THIS IS THE SORT OF DATA I NEED IN ORDER TO BEING MY "PIC" TRANSCEIVER IN ORDER TO COMMUNICATE WITH S2000 AP2 2007 CAN BUS CLUSTER ON FUEL GAUGE, OIL LIFE AND EXTERNAL TEMPERATURE.

REGARDING THE EXTERNAL TEMPERATURE, I' DEVELOPING A PIC CIRCUIT AS WELL THAT WILL FORWARD THE CATCH TEMPERATURE INTO THE DEFINED CODE THAT CLUSTER IS ABLE TO SHOW ON SCREEN.

THIS PART OF CIRCUIT HAS A THERMISTOR LIKE ITSELF SAY OUTSIDE CAR FAREWAY FROM HOT ENGINE ....

No one got the answers, Eagle got it!

Brute force hu? lets see what kind of signal the wire b8 white black strip has, because I dont have nothing at all to catch signals, only this cluster, but lets try all the methods possible to sniff the signal that this wire tries to send to "ECU" as I dont have the "ECU", but lets see what kind of signal this wires send and then lets decode this signal to find the "ID CODE", voltage it has .... all the possible data that can be sniffed without other parts of this circuit.

Well it seems that the sockets and wires are really from this cluster as if I check the other sockets, it does not has this wire on "B8" into the socket.

CAN Frames:

In a vehicle running a CAN bus there are a number of nodes that send and receive data to one another. These nodes are usually things like the engine computer, instrument cluster, abs computer, body control computer etc... They are much like computers on a ethernet network sending packets of data to one another via TCP. The CAN bus uses a much simpler can 11 or 29 bit data format which Wikipedia describes in detail.

Many cars I've tested with only use the earlier 11 bit format. This format consists of an 11 bit header, a 1 bit RTR flag to identify if the message is a data request and a further 4 bits to describe the length of the message data (which can be up to 8 bytes long).

The OBDLink device that I use (which uses an ELM 327 chipset from ELM electronics) does a lot of work for me. It parses the headers for can frames and returns as an integer (i.e. base 10 not hex) along with the data bytes in hex separated by spaces.

For example a frame might look like this: 201 1F 00 0F 00 FF EF A1 7F. 201 obviously being the header identifier and the following 8 bytes the data. Headers need to be turned on to get '201' at the beginning of the data line (use ATH1 for headers on, ATCAF0 to turn off CAN auto formatting and ATMA to get the CAN frames).

WHAT IS THE S2000 AP2 YEAR 2007 CAN-BUS ECT COOLANT DATA FRAME VALUE?

Eagle_Phoenix

As the more perceptive you realized, you can see here, there is no answer! it looks like nobody knows how a can bus data frame works internally and have no information at all for we finish this project, then all I must to do is to re-fresh my mind waiting relevant information, I am tired to try hundreds of things that does not work at all, all I need is the data-frame "ID CODE" for me to finish my stuff, I open hand from oil life ... if I just get what kind of sort code the "coolant temp data frame" works in this can-bus network project, then I will be very happy to finish this project.

Also, the external temperature does not work on canbus like I was thinking, after some strong test diagnoses, I found that it has a thermistor (temp sensor on s2000 2006+ front bumper) this thermistor catch the signal and send to two wires from this cluster that I am still patiently waiting to ****** this white soul.

Eagle_Phoenix

It is good to inform here that I've ordered the full manual from honda s2000 from year 2000 to 2008 "PAYING THE PRICE" and the wires on cluster is confused and does not mention nothing at all in regards what kind of data frame it needs to operate the cluster.

I see here a very "hidden" technology, hidden resources in this car projects that information should be free, only some "mafia" engineers are choosed to have those information, honda refuse to give you any information and just ignore you on every call you make to them.

HOW CAN SOME ONE TEST THIS CLUSTER WITHOUT ALL THE NECESSARY INFORMATION FOR WE DIAGNOSE A PROBLEM? HONDA CHOOSE WHAT INFO THEY WILL REVEAL FOR TECHNICIANS IN ORDER TO FORCE THE CUSTOMERS TO PAY A VERY HIGH PRICE IN THEIR WORKSHOP!!!

THIS IS THE TRUTH!

Eagle_Phoenix

Well, I really tried hundreds of things, but this cluster does not work at all!!!! the only way should be some mod on circuit inside the cluster!!!!

namewasdallas

i think thats more trouble then its worth, i would of just got a couple auto meeter gauges if all your going after is knowing the vitals on the engine. But good luck trying to figure it all out.

Eagle_Phoenix

TAAAAADDDDAAAAAAAAA!!!!!!

I am a person that does not give up easily ... but I confess this cluster was the serious threat of all my projects, because the honda (********) does not want to share the information with me that M******** B********.

I AM FULLLLLLLLLLLLLLLLLLLLLLLLLLLLL OF HATE.

INFORMATION SHOULD BE FREE!
