Turning off service light & other service questions - 850 with OBDII

Just as a quick note on this, I actually checked what filter was on the car and it was an OC204 Mahle oil filter, put on in the previous service by a Volvo Independent...

I noticed Opie Oils are doing very good service packs at the moment with this same oil filter and 6L of quality oils for under £40 (includes 10% forum discount, I used 'ATR' discount code as I spend time modding the Accord Type R forum) - Sounds like a done deal :)

Sump plug washer also ordered, so now ready for the oil service and trying out the service removal light instructions!

Dave - Did you try this instrument test thing?

If you can get the jonesrh webpage/script working then you can change the service interval, etc. I couldn't get it to work on mine as I am running windows virtually on linux and for some reason it won't connect properly via bluetooth.

Have you got a link to this website ?

Not yet, keep meaning to do it. Will try it after tea :)

The good news is you can reset using your phone and the bluetooth elm327 (I have done on my 850 AWD and my V70). You'll need the ElmBasic android app from the Play store and will have to manually enter the sequence but it works.

Here is the code (all credit goes to the guy on the jonesrh website above), send one line at a time via the ElmBasic app (very simple app, just type the line and hit send).

ATZ
ATL1
ATE1
ATDP
ATH1
ATAL
ATKW0
ATTA 13
ATRA 13
ATIIA 51
ATWM 82 51 13 A1
ATSH 83 51 13
B030
B230

Basically the first 12 lines are to setup the connection and select the right ecu (51 is the code for the instrument one), the last two lines select and reset the service light.

---

Just tried the above sequence but unfortunately without success. It communicated and said OK until I got to ATAL, then instead of saying OK as it did with the earlier commands, it returned a '?'.

Wondering whether it's because I'm running an M4.4 mapped ECU, although I'd have thought the service ECU would be elsewhere and independent, as the last service a year ago was on the original ECU. Any ideas anyone?

I do have a copy of the Volvo FCR to try but haven't got the connection cable yet.

Feck. I had high hopes of this...if it helps there is a bit of explanation below:

http://www.matthewsvolvosite.com/for...c.php?p=332575

Just from reading the above & this link:

ATZ - reset
ATL1 - line feeds on
ATE1 - echo on
ATDP - describe the current protocol
ATH1 - headers on
ATAL - allow long messages
ATKW0 - key word checking off
ATTA 13 - set tester address to 13
ATRA 13 - set receive address to 13
ATIIA 51 - set ISO init address to 51
ATWM 82 51 13 A1 - set wakeup message to 82 51 13 A1
ATSH 83 51 13 - set header to 83 51 13
B030 - reset request?
B230 - reset request?

The service light is part of the instrument cluster ecu.

It could be an older ELM version or it maybe that your elm327 adapter is a dodgy copy, which is possibly why the ATAL command has failed.

You could try it without the ATAL as that command enables 8 bytes of data sending (instead of 7 bytes)

You can try this test sequence to see if your adapter is a fake:

Code:

---

The main way to detect if an ELM327 device can talk KWPD3B0 so that it can communicate with the 1996-1998 Volvo 850/S70/V70/XC70 is to...


Detailed steps to detect fake (or partially incompatible) ELM327 devices
 To save some time in isolating fake ELM327 devices, I suggest you use the following detailed sequence:

1. Verify with vendor **before** purchasing that following 6 commands respond with "OK".

 
 
        ATSP 3
        ATAL
        ATKW0
        ATIIA 51
        ATWM 82 51 13 A1
        ATSH 83 51 13
 
 
 If your claimed ELM327-compatible device does *not* respond to all of those 6 commands with an "OK" response, then do *not* buy that device, since it can *not* be used to read the vehicle mileage (and it probably can *not* be used for any KWPD3B0 communication).

---

Thanks for the quick and helpful responses, I've tried both removing 'ATAL' and no success, I also ran the second series of commands and the ATAL is not recognised.

Conclusion seems to be that my ELM327 device is at fault... A pity as it works well for everything else, including helping me previously identify and solve a fault code (split vacuum running rich) and cleared it OK.

Looks like I need to get the cable and FCR to reset the service light.

From the test sequence to check ELM327 operation, only these commands worked:

ATSP 3 (response OK)
ATIIA 51 (response ELM327 v2.1)
ATSH 83 51 13 (response OK)

In fairness, it was only £4 delivered off EBay :lol:

Since you get an OK to ATSH 83 51 13, would it be worth trying the following....it's the last 3 commands from the sequence posted above....expected responses in brackets:

ATSH 83 51 13 (OK)
B030 (83 13 51 F0 30 07)
B230 (NO DATA)

I'll give it a go tomorrow, worth a try to prevent the 2 minutes of annoying orange service light on every start up :-)

Just as an added note - my ELM327 device could read the mileage on my friend's Focus ST (latest version).

Will report back on success of trying some command lines from above, namely the first few down to ATAL, then the bottom 3.

Apparently there have been some issues v2.1 'fake' devices and commands (I say fake as they seem to have bugs in the code from what people are saying). Probably hit and miss on what they do and don't work on :/

There is a lot of very good info on the Jonesrh website about all the different commands and faqs on troubleshooting, well worth a read! Kudos to the guy for going to those lengths to document all that stuff!

And I finally got round to doing that self test video :D Looks like I have a broken segment in the time display :(

Available in 1080p60 too....

Love the dial sweep Dave... impressive it worked.

The gauge test command is the same sequence but instead of b030 or b230 the code sent is b031 or b231 (only b231 works on my v70)

Dave,

1. That's new info for me. Sounds like the S70/V70 ECU 51 B031/B231 might behave similar to the S70/V70 ECU 51 B030/B230 requests -- where the B0xx requests respond with "7F B0 12" (indicating the 31 and 30 subfunctions are invalid for the V70's ECU 51 B0 function) and the B2xx requests are the "actuator" requests. I'm wondering if the '97-'98 S70/V70/XC70 ECU 51 B2xx requests do *not* require corresponding B0xx "get ready for my B2xx sibling" requests.

Can you verify by posting the exact requests and responses as it appears in your terminal emulator or program -- paying extra attention that each character, including linefeeds and spaces, are typed precisely as they appear in your terminal emulator?

I'm wondering if the message exchange looks **exactly** like this:

>b031
84 13 51 7F B0 12 29

>b231
83 13 51 F2 31 0A

where the b031 request can also appear as B031, "B0 31", or "b 0 3 1",
and the b231 request can also appear in either upper case, lower case, or mixed case, and where spaces are also insignificant.

Once you post back what the S70/V70 Gauge Test message exchange looks like (including the B031 and its response), and the message exchange "makes sense" and looks like an accurate verbatim transcription, I'll include the S70/V70 Gauge Test interpretation into the kwpd3b0_interpreter. All you need to include is a single V70 b031 / b231 exchange similar to the one above. No need to test all the case and spacing variants.

Also, can you let me know what year your V70 is?

2. At the present time, kwpd3b0_interpreter detects a Gauge Test initiation when ECU 51 B031 responds with either:

83 13 51 F0 31 08

or

84 13 51 7E B0 23 39
83 13 51 F0 31 08

But from what you are saying, that present interpretation is 850 specific.

It looks like I might need to add another interpretation that is V70 specific.

3. The ECU 51 Gauge Test button that I've included in the next version of volvo850diag, the yet-to-be-released v0.8, might need enhancement so it issues both the B031 and the B231 requests, so it will work with both 850 and S70/V70/XC70. At the present time, that Gauge Test button in the beta test version of volvo850diag v0.8 only issues the B031 request, since I found out that my 850 responds immediately to the ECU 51 B031 request and didn't seem to require the B231 request for anything.

That's another reason I need you to post back the V70's exact B031 / B231 message exchange -- to enhance volvo850diag so the COMBI Gauge Test works not just for the 850, but also for the S70/V70 family.

4. Finally, can you make a fresh test, starting from a V70 that has sat overnight, where you use the commands down thru ATSH 83 51 13,
then immediately issue the B231 (totally bypassing the B031 request)?

Does the V70 Gauge Test get triggered simply by B231 -- without the B031 being used -- when the B231 is issued after *all* the other preparatory ELM327 AT commands [with the possible exception of ATAL])?

Thanks.

Just to answer a couple of your questions now:

* My V70 is a 1997 model year.
* The test in the video above was initiated using only the b231 request and also repeated a number of times by just re-sending b231 (within the same session).

Additionally, in the video I typed all the commands in lowercase with no spacing and each responded OK (though the test was also done earlier in the day using all uppercase and spacing and B031). Is it possible the ELMBasic app formats the commands before sending?

I will complete the tests as you have requested and post the results as soon as I can.

Tried this and got the following responses:

ATSH 83 51 13 (OK)

B030 (BUS INIT... ERROR)

B230 (BUS INIT... ERROR)

Service performed, but service light stays on.

goddammit :cussing:

Don't know if you've turned the light off yet but I saw this on Ebay, I have a similar one & it works on my 98 t4. http://www.ebay.co.uk/itm/Volvo-Serv...YAAOSwo0JWMPyT
