On the opposite side of the speedometer to the trip-counter reset on my 850
is what looks like a blanking plug. It can be removed to reveal a button
which when pushed turns off the light.....
Maybe your car is similar????
For US models at least you need a code scanner to read out what trouble
codes are set and to reset the service engine light. It would be good to
find out what the car thinks is wrong with itself, eh?
Problem: "standard" OBD-II scanners will only display the
fedrally-mandated emissions-related codes. They won't tell you what
faults other systems are displaying, such as airbags, climate control,
radio, etc.. To find out those details, it's a trip to the dealer,
several hours wait, and about $50.00 if you don't pay them to fix it.
Until I find an affordable way to read and understand ALL codes and
OWN a full set of service manuals, I won't be buying a new Volvo.

Software to do it and read all the other ECU's:
Cheap interface cable at:
or make your own at:
I've been researching OBD2 readers and software and what I am hearing
is that the ISO OBD port to serial 9 pin interface is "chipped" by
each OBD software maker to work with their software ONLY, and so you
cannot just make of buy an interface and use it with any software as
is implied here http://www.obdtool.com /
Anyone have the lowdown on this?
Here are some more links to OBD2 software & interfaces:
The makers of software uses different ways of protecting their buisness
selling the software.
Some uses, as you imply, hardware dependent software were some
initialisation of the interface is performed before the actually
communication with the cars ECU begins. Others just make software were you
will have to register to get a key for full functions, these will usually
work with any simple ODBII to rs232 interface. Maybe the tool sold at
http://www.obdtool.com/ is only using a simple hardware interface and would
then work with all other software programs that does the same Like Vol-FCR.
So not any software uses a simple hardware interface, but where exactly is
this implied on obdtools site, I cant seem to find that.
The obdtool.com interface is sold to work with VAG-COM, this software uses a
simple interface and registration as the obdtool.com site says.
You could also make your own at:
but the parts /connectors would likely cost as much as the ready made
obdtool.com interface for a one off.
You are correct. What I meant to say was that the product being sold at
http://www.obdtool.com is not really a bargain at $71 because you are
getting limited functionality unless you spend an additional $99 to upgrade
from the shareware to the full version of VAG-COM. At that point you are
spending as much as many of the other products on the market. Either way,
you are locked into the VAG-COM product since your interface would not work
with any other OBD 2 product. Personally, I would wait to decide which
software I like and is best for my vehicle, then buy the full package.
Again, I'm not saying there is anything wrong with VAG-COM, but at $170 for
the full product, it's not really any better deal then the other products
