Which ELM327 tool will work best with these 850's?

[Ben850]

Has anyone successfully used a Wifi ELM327 device? I have this one http://www.obdinnovations.com/elm327-wi ... e-android/ and so far haven't been ale to get it to work. I have tried changing the scanner type to OBDlink in the .html for volvo850 diag, but I still can't get anything to happen when I hit the Start Realterm button. My PC shows I am connected to the ELM327 but I am not getting any flashing lights on the ELM327 like I do when it is connected to my Ipod. It does show that bytes have been sent and received.

My main goal right now is to be able to pull the mileage on my '97 855R.

I have exactly that unit. I also have its partner unit that is a direct OBD II connection.

They will never retrieve original miles.

Try one of these, for what it is worth.

The original schematic, not my Foo-Foo.
Either way, look up the codes, and pin positions to find mileage as you would from an OBD I port.
I have not even checked the mileage on my '96, But have used it to find fault, and erase codes in My ECC, as well as reset CEL and SEL.
Using the under hood OBD I in my '93, I was able to do all the above.
Lucky to find the odometer had broken only 20,000 miles from the reading.
Enjoy.

I'm definitely not an expert in this sort of thing so please bear with me.

Q1. What is the COM port # that the wireless ELM327 clone uses?

The technical specs say Port 3500. I'm not sure if that is what you are asking or not.
http://www.obdinnovations.com/elm327-wi ... cal-specs/

Q2. What speed is used between the ELM327 and the PC? 38400 (like typical ELM327 clones and the official ELM327 chip)? Or 115200 (like typical ScanTool.net OBDLink devices)? Or something else?

150 Mbps?

Q3. How are inferring that your PC showed you are connected to your ELM327?

When I click on the bar icon to show wireless connections it says connected next to this network.

Q4. Have you used STNterm to verify a successful connection with your car and a retrieval of at least some info -- ie, to perform some easy tests to make sure you can both talk with the ELM327 and send at least one request to the car and get the responses back?

Not yet. I'll have to try that

Q4. Did you follow the steps in volvo850diag's "Installation and Setup of volvo850diag" section?

I thought I did, but definitely may have made an error.

Q5. What step are you getting stuck on in volvo850diag's "First Time Use of volvo850diag and Realterm" section?

When I click on Start Realterm, the paragraphs pop up, but Realterm never starts. If I click Start Realterm again nothing changes.

Q6. Have you allowed ActiveX and Javascript?

I am using IE11. I didn't see the popup box at the top, but two windows opened up asking to run ActiveX and something else I forgot and I clicked yes on both.

Also, you might have a permission problem like Mike91 encountered, involving having to click the Unblock button in the Properties box for each unzipped file.

I briefly checked this, but didn't see anything that indicated to me that files were locked.

I bet I know what's happened!!! You've followed the instructions I listed earlier in this thread that started with

I've been trying to follow instructions on the jonesrh pages and haven't been paying too much attention to what is in this thread.

This is what the top of IE looks like. I am not sure where the box is that I should be clicking on.


I found these activeX options going through the settings and security menu





Not sure if this is relevant

[esl_97_850_T5]

pappatho,

Excellent, excellent debugging input.

I have to go do an errand now, but the two important things that I think you've probably answered for me.

1. Your statement of "two windows opened up asking to run ActiveX and something else I forgot and I clicked yes on both" very likely says you're already gotten past the permissions problem. Good.

2. Your statement of "When I click on Start Realterm, the paragraphs pop up, but Realterm never starts." tells me something did happen, not what you originally said "but I still can't get anything to happen when I hit the Start Realterm button". If several paragraphs appear between the "Start Realterm" button and the "Read All DTCs" button, then you'll have to figure out what the HTML or Javascript error is. On my WinXP IE8, I simply click the left corner of the Status bar, since it has an exclamation mark there. The resultant box explains where the error occurred. In IE11, you'll need to locate the option relating to enabling Script Logging or Javascript Logging or something like that. It will open up a new window, then you perform the action which causes those paragraphs to pop up. If you're reading this after the paragraphs have appeared, then I would press F5 to re-display the page, reanswer how ever many of the ActiveX, etc dialog boxes that allow permission (probably only 1 will appear this time), make sure you have that Script Logging window open, then press Start Realterm, when the paragraphs appear between the Start Realterm buttona and the Read All DTCs button, the Script Logging window will likely have 1 or more errors in it. Make a snapshot of that Script Logging window and post it here.

Let's see if that gets us a step further.

Also, it would still be advisable to test with STNterm. When you do that and you click on the pulldown to see the list of possible COM port values, either make a screen snapshot and post here or write them down and post here. Also, when you click on the pulldown for the speeds, list everything you see from 38400 up to 150000 or the first speed above that.

pappatho,

1. I've had time to review your response more thoroughly. I've also spent some time installing the CP210x drivers for my ELM327 USB clone cable, Realterm, and volvo850diag to 64-bit system that I had recently clean installed with Win7-Pro and which has IE11. Few changes have been made to that system so most things are in their default state. I've duplicated the situation of having an invalid port name in volvo850diag -- what I think is happening with you case now -- to see how it would appear to you on your Win7 with IE11 and can more accurately explain to you what to do about it.

2. The "Security Settings - Interzone Zone" snapshots you included at the end of your previous post have no bearing on IE running volvo850diag, since volvo850diag is run from a local file on your local machine. If anything, the "Security Settings - Local intranet" would apply. But you don't need to waste any more time with the stuff on the Internet Options / Security tab, because you've already clicked those 2 things passed the ActiveX safeguards (by clicking those 2 things after you displayed volvo850diag.html).

All the other stuff in your previous post was quite helpful in understanding what's going on.

3. I'm brand new to the OBDII via WiFi world and my ignorance shows in my earlier post today!

I've done some research at ScanTool.net to see how they verify connections with their OBDLink MX WiFi devices. In all that I've read so far, there has not been a single reference to COM ports, and there has not been a single reference to using STNterm to verify the PC to ELM327 connection or ELM327 to car connection. They seem to be relying on wifi-oriented or network tools.

More importantly, I finally found one of the very first posts in their Hardware / OBDLink MX WiFi forum which helped me to understand the communication mechanism:

http://www.scantool.net/forum/index.php?topic=9266.0

Reading all of Chris Fincher's responses in that post helped me a lot.

The IP address/port mentioned in Chris's responses (192.168.0.10:35000) is the same as the
the IP address//port mentioned in the obdinnovations.com spec that you linked to (IP: 192.168.0.10, Subnet: 255.255.255.0, Port: 35000). Chris didn't mention what the OBDLink MX WiFi subnet address was, but he did mention that the OBDLink MX WiFi, by default, was in SoftAP mode (instead of infrastructure mode), and that the OBDLink MX WiFi will continuously broadcast a UDP hello/heartbeat packet on socket 255.255.255.255:55011. I have no idea from the obdinnovations.com spec if your WiFi ELM327 clone does the same, but it probably does something the same or somewhat similar.

Now I understand why you included the snapshots of the Wireless Network Connection Status and why you referred to an IP address / port. You can tell I seldom ever use wifi . I had just assumed there would be some sort of "wireless to virtual COM port driver", like there is for the ELM327 USB devices. Apparently, such is not the case for the wifi ELM327 devices.

Unless you open up STNterm (if you do) and find something in the COM Port Number pulldown list which you can correlate with your WiFi ELM327 clone, then it seems for the wifi devices, we can forget about COM ports (like COM2, COM4, COM7, COM 26, etc), and we can forget about using STNterm for a wifi ELM327.

4. The following instructions will hopefully be somewhat similar to your case since they were derived from my Win7-Pro system using IE11, volvo850diag, Realterm. I just can't duplicate your WiFi ELM327 clone...

To use volvo850diag, you'll first have to solve any HTML and Javascript errors you have. Like I mentioned earlier today (but used different labeling because I couldn't remember the proper names, and didn't have time to look them up before getting out the door), with Win7 IE11 to find those IE errors:

- Click Tools / Internet Options / Advanced.
- In the Browsing group, check the item "Display a notification about every script error".
- Click Apply.
- Click OK. [Since I do NOT use IE as my default browser, I find it convenient to leave it set this way always, so I'll always see a dialog box when HTML and Javascript errors occur in volvo850diag. But that's your choice.]
- Press F5 to refresh the page.
- Click "Start Realterm" button.

If there's an HTML or Javascript error, the extra paragraphs appear in the volvo850diag window between the "Start Realterm" and "Read All DTCs" buttons to help in debugging, *and* now an IE "Webpage Error" dialog box appears saying:

"Do you want to debug this webpage?
This webpage contains errors that might prevent it from displaying or working correctly. If you are not testing this webpage, click No."

- Look in the scrollable region of that dialog box and locate the first error that occurred.
- Record what line the error occurred on.
- Record what the error is: "Error: Automation server can't create object", "Error: ie_BadId - Specified comport doesn't exist", or whatever it may be.

You might want to copy the line # and error to the Notepad or a file to save them. Then:

- Leave the "Do not show this message again" unchecked.
- Click No. [If you answer Yes to that question, the F12 Developer Tools will run. I think that's overkill for what we're debugging. And it's too complicated for me to explain. But it's your choice on this question if you answer No or Yes. I suggest answering No, then using a text editor like you've already done to edit volvo850diag.html (and, if necessary, the .js file) any further.]

I'm presuming I can help you with the errors that appear in the "Webpage Error" dialog boxes if you include snapshots of them here or in PMs. I just won't be able to help you with the wifi debugging. I'm close to clueless in that arena.

As far as volvo850diag edits go, I would first suggest this:

- Change your scanner_type edit from "OBDLink" back to "ELM327", since a scanner_type value of "OBDLink" will cause OBDLink specific commands to be issued and may also screw up some timing which has been optimized for OBDLink devices. So start with the volvo850diag.html as it was distributed. Then press F5 to refresh the volvo850diag display, and answer Yes to the ActiveX permission prompt.

Then do the following:

- Check if the Start Realterm button is followed by the text <<< Need to "Start Realterm".
- If yes, press Start Realterm.
- If the Realterm window appears, is titled "Realterm for Volvo 850 SVC70 Diagnostics via ELM327", has a totally black Terminal pane without any yellow text in it, then check to see if IE's "Webpage Error" dialog box has an error "ie_BadId - Specified comport doesn't exist".

If the "ie_BadId - Specified comport doesn't exist" error appears, then let's see if we can specify the Wifi ELM327's IP address and port to Realterm, since Realterm *is* supposed to be able to handle IP addresses/ports as an alternative to COM ports. What we're doing in the next several lines is a temporary check to see if we can get the IP address / port to work. Later, we'll hardcode it into volvo850diag.html.

While the extra debugging paragraphs are still visible in volvo850diag under the Start Realterm button:

- Ensure your WiFi ELM327 clone device is plugged in to the car's OBDII port.
- Verify the same way you did before that you are getting 2-way comm between the PC and ELM327.
- Position your IE (volvo850diag) window and your Realterm window so you can see both simultaneously (and preferably in their entirety).

Then In the Realterm window:

- Click Realterm's Port tab, click the downarrow of the Port field, click (double click to scan ports).
- You should then see the phrase "(double click to scan ports)" in the Port box.
- Double-click that box.
- (optionally) make a snapshot of the expanded, newly reevaluated Port list and post here.

Did you have an entry for 192.168.0.10:35000? I have no idea if Realterm has the intelligence to automatically detect the wireless access point, or if this is something that Windows automatically does as part of its stack of network protocols. You can research that yourself, if desired. Click in the Realterm Terminal pane, then press F1. You can also use Start / All Programs / Realterm to get to the Readme, web site, and Change Log. And rather than beating your head against the wall too long, you can just e-mail the author of Realterm to see if it has an ability to talk over a wifi connection to ELM327 WiFi clone rather than how a COM port is used by volvo850diag to access an ELM327 USB clone.

I'll continue with the instructions, assuming that 192.168.0.10:35000 did *NOT* appear in the list.

- In the Port box, replace the "(double click to scan ports)" text with "192.168.0.10:35000" without the quotes.
- Click Open, and observe how the lower right corner of the Port tab changes to a different Port value besides "Port: Closed". [At least, hopefully it changes that way, similar to how it changed today for me when I had edited a wrong value for the port in volvo850diag.html in order to force me having to go to the Port tab, selecting (double click to scan ports), then double-clicking the (double click to scan ports) in the Port block, then clicked Open, and saw the "Port: Closed" change to "Port: 7 38400 8N1 None".

Please click in a free space of the Port tab, make a snapshot of the Port tab, then post here.

Even though you've clicked Open, nothing much (if anything) has happened in the volvo850diag window. What you now need to do is return to the volvo850diag window and press "Start Realterm". Hopefully, the several paragraphs of debugging aids between the Start Realterm button and the Read All DTCs button will disappear, be replaced with "Startup in progress...", then yellow ELM327 commands and responses (along with some comments) will begin appearing in the Realterm window, and the volvo850diag window will finally have several of the buttons shaded to indicate they are now clickable and the Start Realterm button is followed by "Realterm is ready".

If you did not get that far. That is, when you pressed Start Realterm (after having edited the Port to be the proper IP/port), then maybe Realterm just can't handle the wifi connection. But maybe the Baud box on the Port tab needs to be changed. Click its downarray, make a snapshot and post it here. I wouldn't try anything slower than 38400. I have no idea what to suggest as an upper limit. You'll have to research what to change it to, if anything. If I were you, I wouldn't change that unless I had to, since I've seen no documentation on what it should be. I'd try the standard 38400 of typical ELM327 clones, if possible.

In actuality, you might eventually find that you don't even need to press Open after you change a port in the Port box of the Port tab. If you just change to the correct Port, or type the correct Port, then re-press the Start Realterm button on the volvo850diag display, it will most likely connect **IF** you have the correct port and speed.

If you get the debugging paragraphs again after the "Start Realterm" button, then you now know what to do: look at the "Webpage Error". Look at the lines surrounding the line specified by the line #. See if there's anything that might cause the reported error. If you ever get a line # that is past the end of the file, it very likely means you have mismatched parenthesis, brackets, or curly braces.

If you get that far successfully, then there are several different ways to read the mileage with volvo850diag. Two of the ways are to press one of these buttons: Quick Scan All ECUs or Full Scan All ECUs. Two more ways involve pressing: ATZ Setup of ECUs 51/58/01/6E/2E/2F..., then ECU 51 Setup, then ECU 51 Read DTCs, then either ECU 51 Full Scan or ECU 51 Quick Scan. Finally, both Read All DTCs and My Extra Scans will presently read the mileage. You can explore further, or just click Cleanup and follow those instructions.

If you by some chance got the wifi ELM327 operational with volvo850diag, you'll probably want to make the following edit so volvo850diag.html will always try to connect to port 192.168.0.10:35000, so you'll not have to type the IP address / port # again on the Port tab.

- Search for the line that contains the comment "Force Port # here", and change the value of port from "" to "192.168.0.10:35000".
- Save the edit.
- Press F5 to refresh the page.
- Allow ActiveX.
- Click "Start Realterm".

After making the change to volvo850diag.html to hardcode the corrrect port (using the IP/port that just worked for you), once you click Start Realterm, hopefully you'll immediately see it connect and all the yellow text appearing in the Realterm window and the "Realterm is ready" appearing a few seconds later on the volvo850diag display. That's the way it'll behave in the future.

If you find that you have to up the speed on the Realterm Port tab above 38400, then the way to hardcode that in volvo850diag without changing the scanner_type is to add a line in volvo850diag.html that defines RT.baud after all the other lines that define it and set it to whatever value you've chosen.

5. Oh. By the way, in my Win7 IE11, I also did *not* see the box at the top of the IE window (ie, like it appears in WinXP IE8). I saw some such window at the bottom of the IE11 window. I didn't read it carefully to see if it was worded exactly like the IE8 window at the top or not (and/or if it was essentially the contents of the 1st ActiveX oriented dialog box in IE8). Plus, I didn't have 2 dialog boxes to answer Yes to after that one at the bottom, I only had 1 dialog box. I think that's the scenario that you encountered.

Good luck.

6. I will say that, after my research on Sunday, I no longer have confidence that an ELM327 WiFi clone or a OBDLink WiFi clone can work with volvo850diag / Realterm. I will go ahead and buy one like you bought so I can verify myself if they can be used with volvo850diag or not.

And I will go ahead and buy one of the cheap Bluetooth ELM327 clones that mika bought and one like hauf???? from Austria (in the 2nd post) bought in order to verify for myself if the Bluetooth devices can be used with volvo850diag or not. It'll be interesting to get those questions resolved.

quick update


There was not really gibberish from the ELM327, like I mentioned previously. The only error was that when typing the hex data into the kwpd3b0_interpreter I had typed an O (letter) instead of the 0 (zero). I typed:

85 13 51 F9 03 B8 43 EO

but I should have typed:

85 13 51 F9 03 B8 43 E0

just like the ELM327 had responded with.

So, there is a code you can use for an 97 850, and a different one that works for the s/v/c 70 1998. Look on jonesrh.info. There is also a condensed code version, shorthand.

type in code into ELM, type it into interpreter box on jonesrh.info, and voila you just figured out some valuable information. If you get an error with the confirmed working codes, chances are you screwed something simple up. dont fret, easy fix.

When using the interpretor, type in some info like "Johns V70" with your code you want to translate, so if you run into problems, esl_97 can help you, he gets a log on his website of all the requests

I will write my response as a new user that had a fresh experience around all that.

I am a student, so budget is really low. I had trouble around different matters to get connected to my obd2. Eventually, it got solved. now.

I had bought the cheapest elm327 bluetooth obd2 adapter from china. around 5 bucks I think, free shipping, arrived in 2-3 weeks.

I downloaded (not paid, and I am not suggesting you do that) Torque Pro Android app.

It successfully connected, gave me real time data, and read trouble codes ( as far the app can reach ).

I downloaded the free app, Elm327 OBD Terminal -> https://play.google.com/store/apps/deta ... inal&hl=en

Following esl's command list from his jonesrh.info



then saved the log on my phone, transferred it to my computer, and pasted to his interpreter and got the info. link -> http://jonesrh.info/volvo850/kwpd3b0_interpreter.html

The gleanings will show all the info you need.

In his website there is a write up about how to set/reset the service light, that I did not study, but it should be easy as well.

I know he has already posted all that, I just thought I would share my version of tracking the mileage on the cheap. A huge thanks from me!

[rspi]

First off, I apologize for my lack of involvement in this thread. As I have been reading it, trying to absorb the information, I'm struggling with making it work as simply as I'd like.

In the meantime I ordered and received a cheap tool from China that is suppose to reset the service and SRS lights from many auto brands. A recently acquired 2 '96 850's, both having a service light on. The tool DID reset the service light in one car, have not tried the other.

Both cars have broken odometers and I had a local indi shop read the mileage from the clusters through the OBD2 port. One car showed 173,998 miles but actually had 260,5xx stored in the cluster. The other shows 216,xxx and has 227,4xx on it. Thus my desire to be able to read this info...on the "fly".

When I repair one of these odometers, I'm going to set off a SRS light so I can test the tool to reset the code.

Sad thing is, I believe that my ScanGauge 2 can do the features I want, I just don't see where anyone else has tried to use the program features of the ScanGauge 2 to figure it out.

[esl_97_850_T5]

I has a little time today to work with this. I made it to the "- Click "Start Realterm" button." and nothing happened today. The paragraphs didn't come up as I had previously seen. I think I may just buy a bluetooth ELM327 or a cable one and try that way.

pappatho,

I suggest the ELM327 clone USB cable as picture on the http://www.totalcardiagnostics.com/supp ... 2-software page. Make sure you get one that is CP210x based. That's the simplest way to get volvo850diag going.

esl_97_850_T5

[esl_97_850_T5]

... I had a local indi shop read the mileage from the clusters through the OBD2 port. ...

...Sad thing is, I believe that my ScanGauge 2 can do the features I want, I just see where no one else has tried to use the program features of the ScanGauge 2 to figure it out.

Robert,

1. How much does the indy shop charge you (if anything) to read the mileage?

2. Since you are the one that wants to use the ScanGauge 2 to read the mileage (or do whatever), you are elected to be the one to figure it out. Necessity (and desire) is the mother of invention.

But I wouldn't waste my time on it. I don't think the ScanGauge 2 has the capacity to perform a non-OBDII emission diagnostic, KWPD3B0 targeted, ISO 9141-2 based connection, allowing you to control all the commands that are issued to it, both before and after the connection (like you can do in a terminal emulator). It seems to me the ScanGauge 2's programming capability is primarily limited to deciding which OBDII emission diagnostic oriented PID to use.
