Resetting service light

[harvest14]

I know we like our Volvo cars and all, but what should we think of a corporation that tries to strong arm people into getting all their oil changes at the dealer? If Volvo corporate is capable of designing, manufacturing and marketing a car with such a feature; perhaps we should be afraid of what else they have been or ARE capable of doing. At least they only did it for a few years. Perhaps their conscience got the better of them? lol

Meh. Every car company does that these days. The German ones are the worst. I'm sure they got flak for it though, so they changed it to be resettable again in 1999.

It's threads like this that make me appreciate my '93 and its OBD I.

I had actually ran codes, and reset the service light this very morning.

By the dealer or the correct tool

Correct tool will be Vol-Fcr from e-bay for around 30$.You get vol-fcr software and a cable for that price.

[misha]

Yeah, that was it. Pretty scarce now.
I found this at a Chinese site and was asking about volume pricing, say 50 units. Not too good, I was hoping for something like 3 to 5 bucks. The lamp is only lit for like two minutes anyway. Never actually bothered me much but then it usually has the Check Engine Light to keep it company anyway.

Vol-Fcr can be found on e-bay or amazon for around 30$.With Vol-fcr,you are getting the whole package.Reset service light,read & clear engine,abs,power seats,instrument cluster,transmission,immobiliser 1 & 2 codes,ac...etc.

Engine codes can be read & cleared ONLY if you have Motronic 4.4 engine menagement.For U.S market that would be from '98-'99 n/a models.For european market....Motronic 4.4 started from '97 850-'late 98 s,v70.

Actually, Motronic 4.4 was first available in US model 850s in 1996. I've got two 96 NAs with 4.4.

1996 turbo: All are 4.3
1996 NA: some are 4.3, some are 4.4
1997 turbo: some are 4.3, some are 4.4
1997 NA: some are 4.3, most are 4.4
1998 turbo and NA: all are 4.4

For a 96 or a 97, the easy way to figure it out is to check the VIN:
http://new.volvocars.com/ownersdocs/199 ... n1996.html
http://new.volvocars.com/ownersdocs/199 ... n1997.html
http://new.volvocars.com/ownersdocs/199 ... n1998.html

I would *guess* the timing for 4.4 in the European market was similar, just account for the usual difference in model versions.

I have my oil change schedule set on every 5k (+/- 500 miles). I use full synthetic so that should be good. So I'll change at 230k, 235k, 240k, etc. If I'm about to go on a long trip I'll with do it before or after. Makes it easy to remember. I also write the miles the oil filter which helps me in a pinch on other cars like my daughters which may drive 2,000 miles in 4 months or 3,000 miles in 2.

I use to drive about 40,000 per year but I'm down to 20,000.

[abscate]

I copy and pasted the following (posted above) from a site *** somewhere ***

Ignition off.
Press in trip odometer reset button.
Switch on ignition.
Continue pressing in the reset button for 10 seconds. (Sing one third of the "Final Jeopardy" theme
Release reset button within 4 seconds.

...but my 1999 V70 is slightly different.

Ignition off
Press and hold odometer reset button
Turn key to RUN position, continue to hold odometer reset button
Wait approx 10 seconds for SERVICE light to begin flashing
Then key off.

Voila!!

Anybody heard of the AST 5408 Volvo Service Light Reset Tool? It apparently resets the 96-97 models in about 6 seconds...

[esl_97_850_T5]

An ELM327 device along with terminal emulator software is another option for resetting the SERVICE light of the 1996-1998 850 / S70 / V70 / C70 / XC70.

1. The resetting of the SERVICE light is quite simple with an ELM327. It appears to be a 2-step sequence of B030 / B230:

ATSH 83 51 13
B030
B230

Assuming you already have your ELM327 connected with ECU 51 (COMBI) and the ELM327 is performing the KeepAlive exchange every few seconds, those 3 commands/requests and their responses appear as:

>ATSH 83 51 13
OK

>B030
83 13 51 F0 30 07

>B230
NO DATA

2. A more expansive (colorized) view of the actions necessary to reset the SERVICE light via the ELM327 is...

Start with: a) terminal emulator on your laptop / tablet / phone / etc which is ready to talk with the ELM327 compatible device, b) ELM327 plugged in to Volvo's OBDII port and "physically" connected to your phone/tablet/laptop (via Bluetooth pairing, USB port, serial port, wireless), and c) either engine is on or ignition is at pos II.

Then, using your terminal emulator, issue the following ELM327 AT commands and B030 / B230 special Volvo keyword D3 B0 protocol (KWPD3B0) requests in order to reset the SERVICE light on 1996-1998 850 / S70 / V70 / C70 / XC70.

The complete list of setup commands is:

ATZ
ATL1
ATE1
ATI
ATSP 3
ATDP
ATH1
ATAL
ATKW0
ATTA 13
ATRA 13
ATIIA 51
ATWM 82 51 13 A1
ATSI
ATSH 83 51 13

The actual SERVICE reset requests are:

B030
B230

where:

- Most AT commands respond with OK.
- ATZ identifies the ELM327 version, but its output is garbled.
- ATL1 further garbles the ATZ output, but corrects the linefeed situation.[/b]
- ATSP 3A or ATSP A3 can be substituted for ATSP 3.
- ATDP must respond with either ISO 9141-2 or AUTO, ISO 9141-2.
- ATKW0 is the keys: A, T, K, W, zero.
- ATI and ATSI are optional. You can delete them if you want to. Also, ATE1 is usually optional, since it's usually the default.
- Even the ATSP 3 and ATDP commands are optional if you already know your protocol is setup correctly.

Refer to this ELM327 ECU 51 commands & responses example to see how most all of the ELM327 AT commands should respond. That example works for 1996-1997 850, probably works for 1998 S70/V70/C70/XC70, and might even work for other Volvo years/models (especially those that Vol-FCR can talk to).

The last 3 commands/requests -- ie, the 2-step Reset SERVICE Light sequence -- respond as follows:

>ATSH 83 51 13
OK

>B030
83 13 51 F0 30 07

>B230
NO DATA

You always get a NO DATA response to B230, even if you increase the NO DATA delay to its max of 1 sec. Apparently, that's just the way the COMBI implements the resetting of the SERVICE light -- without a keyword D3 B0 protocol (KWPD3B0) response.

However, if the response to B030 is NO DATA or anything besides 83 13 51 F0 30 07, then the SERVICE light reset will not work.

Depending on which ATSP command you use and whether you use the ATSI command or not, a BUS INIT: ...OK line may also appear once the ISO 9141-2 connection is established.

3. As long as you see all these 4 lines in this order:

>B030
83 13 51 F0 30 07

>B230
NO DATA

then an immediate check of the ECU 51 B9xx data will reveal B904 = B903, B906 = 0, B908 = 0, and, at next engine on, the SERVICE light will be off [unless you've sadistically reprogrammed one of the SERVICE interval limits to zero to make the SERVICE light to *always* come on at engine on].

If you have no need to see the counters set to zero, just go ahead and turn the ignition to off, then turn the engine on.

Voila! The SERVICE light does not come on now!

4. A one push-button version of the above sequence will be available in volvo850diag v0.7 (once it is released, sometime before 2014-08-01).

5. If you want to read your mileage at the same time you do the SERVICE light reset, just throw in a B903 request either immediately before the B030 or immediately after the B230. It's probably advisable to *not* break up the 2-step B030 / B230 sequence.
