Some of our most frequently asked questions on our OBDII and EOBD tools
have seen these/similar products advertised as working on all 1996 and
newer cars - why don't yours?"
just bought an OBDII/EOBD tool from someone else that was advertised as
working with all 1996 and newer cars.
Why doesn't it work on my [1999 Vauxhall Vectra]?"
is the answer...
1996 in the United States, a Federal Law came into force requiring
all US-sold cars to be OBDII compliant. Most OBDII tools
are therefore advertised as working with all cars from 1996.
OBDII Federal Law applied only to cars sold in the US.
the UK and the rest of Europe, our equivalent law (European On-Board
Diagnostics, or EOBD) did not come into force, and more importantly,
was not fully implemented by our car manufacturers, until 2001 for
petrol cars (2003/4 for diesels).
an OBDII tool is sold in the UK/Europe claiming to work on all cars
from 1996, this is highly unlikely to be the case.
where a seemingly identical car may have been sold in Europe and
the US before 2001, from our own testing and research, it is rarely
the case that the European model will be OBDII/EOBD compliant.
fact that we sell these tools as only working with 2001 and newer
petrols (and similarly 2003/4 diesels) is due to the fact that we
are being honest in the coverage, rather than simply duplicating
the sales information from the US.
So do these tools work with any UK/European cars before 2001?
they do, but certainly not across the board, and very rarely back
as far as 1996. A few manufacturers that we know have some OBDII/EOBD
support (on petrol models) before 2001 are listed below:
(most petrol cars using the EEC-V engine management system)
Jaguar (most models from the beginning of the X300 series)
Volvo (some models)
few examples of manufacturers that we have had very little success
connecting OBDII/EOBD tools on pre-2001 models are:
be aware that we do not try to sell these tools as something they
