This page contains two lists composed of a) ELM327 commands, b) OBDII emission diagnostics commands, and c) Volvo specific keyword D3 B0 protocol (KWPD3B0) commands. The OBDII and KWPD3B0 commands are both formatted for ELM327 processing -- ie, they don't contain the ISO9141-2 header or checksum, since the ELM327 will add the header and checksum when transforming the commands into requests which the Volvo can understand.
The two lists are:
elm327_volvo_850_svc70_scan_all.txt, which makes a fairly thorough scan of the '96-'97 Volvo 850 and '97-'98 Volvo S70 / V70 / XC70. This is referred to as the "full blown" or "all" scan.
elm327_volvo_850_svc70_scan_combi_and_all_dtcs.txt, which scans the basic COMBI data -- ECU 51 B9xx and A5xx values -- as well as all the DTCs of all the known ECUs. This is referred to as the "quick summary" or "quick" scan.
The following elm327_volvo_850_svc70_scan_all.txt list contains the commands to perform a fairly complete scan of your 1996-1998 Volvo 850/S70/V70/C70/XC70.
If you copy from:
-- Begin elm327_volvo_850_svc70_scan_all.txt.
to:
-- End elm327_volvo_850_svc70_scan_all.txt.
then save that into a text file on your local machine,
it can serve at the very minimum as a useful "cheat sheet" of commands.
You can manually issue the commands/requests to the ELM327 using STNterm, Hyperterminal, Realterm, Tera Term, ZTerm, PuTTY, ptelnet, ckermit, several different Android-based ELM327 terminal emulators, etc. Or you could experiment with one of the terminal emulator's Send File mechanism to try and get the scan at least somewhat automated, assuming:
So far I've experimented with Realterm and have discovered several different ways to communicate with the Volvo 850/S70 via Realterm and the ELM327. The most useful are:
The PutString mechanism in the ActiveX interface. This is the most versatile, since it sends quickly, doesn't generate any unexpected characters (ie, unexpected linefeeds), and when driven by a program that can accurately delay before issuing the next PutString, can be the workhorse of an automated Volvo 850/S70/V70/C70/XC70 scan.
The Send ASCII mechanism. This can be used from either the ActiveX interface or from a WinXP CMD batch file, as long as the "Canned" strings are loaded beforehand. This approach is useful to lessen typing, but it doesn't allow the automation of sending many commands for several minutes.
Interactive typing, just like you can do with Hyperterminal or any other terminal emulator.
The following was originally useful, but is no longer recommended, due primarily to the a) STOPPED message, and b) connection problems mentioned below:
The Send File mechanism. I originally made a lot of progress with this approach. But it's noticeably slower than the PutString method, and I haven't been able to eliminate a stray linefeed that is getting generated (apparently from Realterm) in an untimely manner to cause the ELM327 to stop its present operation and generate a STOPPED message.
I have not been successful at using Realterm's "Send File" mechanism alone to establish a connection when issuing the ATSI command to explicitly perform an ISO9141-2 Slow Init or when issuing any OBDII or KWPD3B0 command which implicitly causes the ELM327 to attempt a Slow Init (usually a 0100, AE01, or B9F0 command). However, the ATSI, 0100, etc can successfully be issued manually in Realterm's terminal pane or, better yet, can successfully be issued via Realterm's "Send ASCII" mechanism. You can even use the "Send ASCII" mechanism at a specific time during a "Send File" operation in order to force the connection to succeed.
Even though the "Send File" mechanism does lessen typing, it is vastly inferior to using a program to control the timing of sequences of PutString calls.
Do not type the comments which are included in (parentheses) on the right side of the lines with ELM327 commands or data.
You do not need to type the comments that begin the line with hyphens (----) unless you absolutely want to. Otherwise, they'll generate unsightly question marks in your log. Only include the comments if you need them for explanation, or if they are getting automatically sent when the PutString or "Send File" mechanism is being used.
The ATSI and following ATBD and ATKW commands are optional.
To make it easier on yourself, checkout volvo850diag (online docs). That page describes, volvo850diag, in which an HTML GUI, displayed by Internet Explorer and driven by Javascript (which has a timer mechanism), is controlled by you, using the volvo850diag buttons, to make Realterm send groups of ELM327 AT commands, OBDII emission diagnostic commands, and KWPD3B0 commands in a reliably throttled, well-timed manner, so that the Volvo 850 / S70 / V70 / C70 / XC70 and ELM327 have enough time to finish responding.
volvo850diag uses Realterm's PutString mechanism very heavily, preloads the most likely commands that might be used by Realterm's "Send ASCII" mechanism to send individual commands, is very compatible with interspersing interactive input in Realterm yet eliminates (almost all) of the need to type interactively, and still allows use of Realterm's "Send File" button [though the latter's use is not recommended].
volvo850diag runs on a Windows (eg, WinXP/Win7/Win10) system.
volvo850diag is free and open source. It uses a Javascript file that can be customized by Volvo owners to add, delete, or rearrange commands, even if they have no prior Javascript programming experience.
volvo850diag should be considered if you want to avoid all the interactive typing of commands, or if you want to see examples of programming automated scans of the Volvo 850/S70/V70/C70/XC70 with various combinations of ELM327 AT, OBDII, and KWPD3B0 commands, along with the delays necessary so it all flows well.

---- Initial one-time setup for an ELM327 to establish the ISO9141-2 protocol.
-------------------------------------------------------------------------------
---- This first section only needs to be done if it never once has been done
---- for your ELM327 device, or if the protocol has been changed from
---- "ISO 9141-2" while working with other vehicles or while attempting to
---- connect with an ECU which does not exist on your vehicle.
----
---- A protocol change might have been forced by you or some software which
---- you are running, or the protocol might have been automatically switched
---- by the ELM327 device itself after either a successful or a failed
---- connection.
----
---- Some of you will be able to successfully substitute ATSP 3A for the
---- ATSP 3. That's especially the case if your vehicle contains *all* the
---- ECUs whose connection is attempted. However, many of you must use the
---- more restrictive ATSP 3 command which tries only "ISO 9141-2" connections.
----
---- Hint: I strongly suggest using ATSP 3 the very first time you use your
---- ELM327 device with your Volvo 850/S70/V70/C70/XC70. That will
---- eliminate some unpredictable variables. Later, you can experiment
---- with trying ATSP 3A (to allow for greater flexibility when working
---- with additional vehicles).

The following elm327_volvo_850_svc70_scan_combi_and_all_dtcs.txt list is essentially a "quick summary scan" of a 1996-1998 Volvo 850/S70/V70/C70/XC70. It's focus is: a) the most essential COMBI data, and b) all the DTCs of all the known ECUs. This is the one to use when you want to save some time -- when you just want to know if there's any DTCs and also want to check some of the COMBI data.
If you copy from:
-- Begin elm327_volvo_850_svc70_scan_combi_and_all_dtcs.txt.
to:
-- End elm327_volvo_850_svc70_scan_combi_and_all_dtcs.txt.
then save that into a text file on your local machine,
it can serve as your "quick summary scan cheat sheet".
You can manually issue the commands/requests to the ELM327 using a terminal emulator. Or you could experiment with the terminal emulator's Send File mechanism to try and get the summary scan somewhat automated.
Do not type the comments which are included in (parentheses) on the right side of the lines with ELM327 commands or data.
You do not need to type the comments that begin the line with hyphens (----) unless you absolutely want to.
The commands have been drastically minimized in this "quick scan" in expectation that you proceed strictly sequentially thru this file, and might very well be doing so by interactively typing the commands. All ATSI, ATBD, and ATKW commands have been removed.
As mentioned previously in a "...make it easier on yourself, checkout volvo850diag..." hint, download the latest volvo850diag.zip. It'll save you lots of time if you're able to use it with Internet Explorer on a machine running Microsoft Windows.
On an Android device, the easiest way to accomplish the essentials of the following scan is to just download xiaotec "850 OBD-II" app from Google Play, then use its "Scan" function, and review its resultant Summary page.
