vag com don't work Suzuki sds! :(
Vag com= FDTI chip cina version + LM 339

well the idea above was to use something that can talk in obdII,  Not sure if that worked out

can anyone expand on the meanings of the bits in the statusOfDTC byte?

this byte follows each DTC in response to the ReadDiagnosticTroubleCodesByStatus service, and the notes in ECUeditor indicate:

 

' 0x01 bit0 = pending fault present

' bit1 = pending fault state

' bit2 = test running

' bit3 = test inhibit

' bit4 = test readiness

' 0x20 bit5 = DTC validated and stored in non volatile memory

' 0x40 bit6 = validated fault preset at time of request

' 0x80 bit7 = validated fault has been present during this driving cycle

Kashima,
Can you tell us the exact commands you use with the ELM to estabilish a connection ?
This would help people develop more sds tools, maybe on Android phones too.

Thank you very much Kashima,
very apreciated ! :)

Some of you may find also this interesting - not tested yet so may not work as its only based on reading the disassembled code. 80 12 F1 02 21 08 monitor sensor data 80 12 F1 03 14 00 00 clear dtc 80 12 F1 04 18 00 00 00 dtc monitoring 80 12 F1 01 3e keep alive not all below mentioned are tested... 80 12 F1 06 a5 01 80 00 00 00 set pair on 80 12 F1 06 a5 01 00 00 00 00 set pair off 80 12 F1 06 a5 02 not applicable 80 12 F1 06 a5 03 80 00 00 CKS set excva on 80 12 F1 06 a5 03 00 00 00 CKS set excva off 80 12 F1 06 a5 02 not applicable 80 12 F1 06 a5 05 28 RPM 00 CKS set ics rpm value, value needs to be between 54 and A0, rpm is =(HEX2DEC(RPM)*2^5)/2.56 80 12 F1 06 a5 06 80 00 00 CKS set fan on 80 12 F1 06 a5 06 00 00 00 CKS set fan off 80 12 F1 06 a5 07 80 00 00 CKS set evap on 80 12 F1 06 a5 07 00 00 00 CKS set evap off

Hi,

 

I´m about to program some kind of SDS-tool in VB. Monitoring of sensor data works fine. Logging as well.

 

I establish communication starting with wake up pattern (WuP) followed by

byte	1	2	3	4	5
wert	81	12	F1	81	5

 

Then I loop request to ECU by a timer of 150 ms

ptr	0	1	2	3	4	5	6
Len					1	2
Value	80	12	F1	2	21	8	CS

 

And read response with sensor values. That works fine. I can read the desired idle speed (seams to be that value) and the ISC-valve position.

 

Now I want to implement more SDS functionality. For example test of ISC-Valve by setting desired idle speed to different values temporarily.

 

I tried to start with the WuP followed again by

byte	1	2	3	4	5
wert	81	12	F1	81	5

 

Then I looped according to PetriKs discovery

byte	1	2	3	4	5	6	7	8	9
wert	80	12	F1	6	A5	5	28	RPM_Set	0	CS	CS is greater than &HFF!

With &H68 for RPM_Set (should be 1300 rpm), but idle stand at 1150 rpm. Dont have a clue....

In ECU-Editor data are sent by "txbyte" declared as Byte. But what if checksum is greater than &HFF? That´s the case with PAIR ON funtionality as well: cks is &H2AF. I suppose cks is not sent copletely due to declaration as byte...?

could somebody give me a hint please?

 

            with kind regards, Torsten.

I can't tell if this is old news or not so I'll throw it out on the off chance that it is of interest.

I've been studying the pds file saved by the SDS software. It seems like there's a good chance that the saved values are the same as in the K-line data stream. The relationship between those values and engineering units is as follows:

RPM = Value*100/255
Throttle position (°) = Value*125/255
Manifold pressure = (Value*5 - 153)*133/4/255
Temperature (C) = Value*160/255 - 30
Temperature (F) = Value*288/255 - 22
Voltage = Value*20/255
Secondary throttle position (%) = Value*100/255
EXCVA sensor = Value*100/255

There's a division by 255 in every relationship.

Edit : I found the problem : an option in the bios ( serial ) must be active to make the software working on windows 7 and windows XP.

-- Edited by songotag on Wednesday 1st of August 2012 08:51:32 PM

 What is this option?

---

 The option is " use serial " on my laptop. It's a HP 6710B, an there's no physical serial port on it. But if i whant he kashima's software working, i must anable this option.

 

I' interesting of programming a pic to check the sensors values ( via the ODB connector ) of the strom to display on a small LCD screen.. but i don't know how to do...

Windows xp framenetwork ??



windows xp framenetwork 3.0

Problem solved.

' 0x80 bit7 = validated fault has been present during this driving cycle

But I'd like to know the meanings of these descriptions in more detail. For example, what is the difference between bit0 and bit1 (the descriptions look almost the same to me)? 

And what do bits 2,3,4 mean? (i.e. what does test mean?)

If a particular DTC appears more than once in the response, what does that mean? (each time with a different status value) ... for example, in one response I got three successive IAPS codes:

01 05 A2

01 05 E1

01 05 A0

Unfortunately the ISO14230/KWP2000 standards are of no help here, as they simply state that "Format and length of this parameter are vehicle manufacturer specific." 

any help muchly appreciated,

cheers,

Mark

 Hello Bozo

I plan to make an OBD on the dashboard of my VSTROM 650. I saw on another forum that you made an OBD that reads information directly from the OBD connector. Is what you can give me information on your projects?

I would like to make an OBD playback to display the gear engaged, consumption, defects etc ...

thank you and see you soon

Hi,

this works for my hayabusa ...(please see image below)

Hello,

I'm working on my arduino board to read some information from the ECU of my vstrom 650 k8.
When i'm sending this comand to the ECU :

Who knows witch byte is for gears, temperature of oil....

thank you

Hello Songotag,

I also want to make an Arduino Nano board with 16x02 LCD screen communicating with my Vstrom 650 K8.

I already have an Arduino Nano R3

16x02 I2C LCD board

DHT11 sensor (for temperature an humidity)

And the diagnostics connector.

 

I use a program based on http://forum.arduino.cc/index.php?topic=236092.45

But I have not tested it yet. How do you proceed?

 

Is anybody has the formulas  for SPEED, RPM etc for VSTROM 650 k8, I tested all the formulas in this forum and there is that good engine temperature, ECT; TPS and BAT formulas for my bike.

 

Formulas OK :

 ECT = k_inByte * 160 / 255; // BillV, 

 TPS = (k_inByte * 125 / 255);  // petrik

BAT = k_inByte * 20.0 / 255;

Probably Kashima or Petrik ????

thank-you

I am not sure what exactly you are looking for, do you mean RPM?

If yes that should be it:

to_byte="x*2.56"
expression="x/2.56"

Let me know if that it all or you need more, this is Mitsu ECU or Denso?

---

 Hello Carry, RPM is Rotation Per Minute

 For Speed, i have :        SPEED = (byte24 * 2 );

for RPM :

 RPM1 = Byte25* 100;          RPM = (byte26* 100 / 255) + RPM1;

I think my ECU is a Denso, how can i be sure ???

I know that i must use two byte to calculate the RPM but my formula give me a bad number.

Thanks for your help

 

PS : You probable know how to flash a Denso ECU to remove TRE ??

-- Edited by songotag on Monday 6th of June 2016 10:16:58 AM

could you please paste the results back onto this forum? Then we can also use it.

Hello, some news for my Vstrom 650 k8:

For RPM, i've an accurate value with this : RPM = byte_25 * 1000 / 15.3;

ECT : ECT = byte_29 * 160 / 255;

IAT = (byte_30 * 0.82 - 30); // from moh

BAT = byte_32 * 20.0 / 255;

Have fun

 Thanks. I am using PuTTY (similar to Hyperterminal) and using your commands on OBD Link SX (STN chip). It works like a charm. But I have an iCar VGate device also (ELM 327 device). It doesn't work. On hitting command for show DTC (18 00 FF 00) it shows NO DATA. How is it possible? There is an app called SZ Viewer which I used with the iCar VGate device and it works. But your commands don't. Are there any more commands to be hit to configure the device? Are there any AT commands like AT SW or AT ST (timeout) etc that needs to be put before your commands?
