reset service engine light.
 

found these instructions:
1. Press and hold odometer reset button.2. Turn ignition switch to Run.3. After SRL flashes, release odometer reset button.4. Confirm by turning your Volvo off, then on again.

but cant get it to work for me. does anyone have any advice. perhaps more detail as to when to release the odometer?

Try turning the key to first detent, THEN holding the button in.

I have a 2000 s70 and I followed these instructions and it worked.
How to Reset the Service Light on the Volvo S70 | eHow.com

As I said in the other discussion, that trick only works on SOME 1999 and 2000 S70s. Those of us with 1998 models or 1999s without the feature have to have the tool.

Disconnect the negative battery terminal?????? Make sure to disconnect your radio before that like the books always say. Damage to the microprocessor may occur ;) (which has never happened to me all the times I have).

OMG THANK YOU!!! This trick worked on my girlfriend's 2000 c70, woooo! That light has been on for years now....LOL

i have a 98' v70 with the service light on. nothing seems to turn this thing off except for running for about 2 min. what is "the tool"?

google search for "Volvo service light reset tool." They cost about $160. Really not worth messing with.

it worked on my 2000, yeh

LOL, just use an obd2, most auto parts stores around here will let you 'borrow' it to use in the parking lot

That will not work on the '98 models.

If you google the
Draper Expert Volvo Service And Airbag Indicator Reset Tool

you will find it in the UK for about $50.

Long wait, a little confusing to buy (amazon.co.UK).

However, it works just fine on my '98 S70 T5

I have an obd-2 scanner and can reset the check engine light, how can I use it to reset the service light?

Special Tool To Reset The Service Light...
 

Kenny, your kidding right??? :cool: I know it's been said about 10 times in this thread, you can NOT reset the Service light on these cars without a special tool, NOT an OBD-II reader.

This is rather difficult. If you can find the communications specifications, you will need to program your OBD2 reader to write the proper code to do the reset. If you do not have the comms spec, you will need to find a way to monitor the pin on the OBD2 port that the command is being sent through, and if it is OBD2, you can put an OBD2 "sniffer" parallel to your reader. It would be good if this was bidirectional, so you could check the responses (I think it may be, since I hear that the time varies for how long it takes to reset).

Once you are done doing this, take your comm logs (whoops - forgot to mention that earlier) and whatever programming software you use to communicate with your OBD2 unit, and you should be able to whip up a VB or C++ program to duplicate what you just saw.

I'm going to admit here that I have not tried this. This is just a core set of tasks that assumes that you have a certain level of computer proficiency.

It also assumes that your OBD2 reader is just an adapter for a program in your computer, and not one of these "all in one" units that isn't programmable - I didn't give eprom burning instructions here, since they are different for each reader.

After years of reading that I need the $160.00 tool to reset the damn thing someome has found a way to convince me that $160.00 is a BARGAIN! Thanks Mike.

Amen.

I have a Scan Gauge II and I know there is a way to program it to turn the freeking service light off but I have not figured it out. It's sad that ScanGauge has not done it, I'm sure Volvo's are not the only car that needs the light turned off.

I have seen a tool on eBay for about $79. It was out of Europe or China so I didn't bother getting it. I may check with the Volvo salvage yard that is closing down to see if he'll let go of his.

I don't know if posting links is ok, but I'll try.

The product is a draper 69007 - this web site is advertising it for $5.53 (although I am sure it does NOT include shipping from Hong Kong).

I paid 10 times that much.

Maybe somebody can point out to me what I am missing on this one - is it a well done scam to steal my credit card info?
