Generic OBD-II functionality.
Because many of VW's recent factory repair manuals no longer have
traditional 01-Engine "On Board Diagnostic" information and have
replaced it with "Generic Scan Tool" data, this has become much more
important than it was in the past. For now, we'll
let the screens speak for themselves. Click the "Mode"
buttons for an interactive demo:
New Version 1.8 and newer of VAG-Scope
is able to
graph generic OBD-2 Mode 1 data:
Generic OBD-II functionality is "Supported"
only on VW, Audi, Seat, and Skoda cars. It will
likely work on many other brands of cars. We'd be happy
to receive feedback as to what other brands and models of cars it
does and does not work on, however, we do not feel obligated to make
it work on other manufacturer's cars.
Generic OBD-II functionality is limited to
cars using ISO 9141-2 ("CARB"), ISO 14230 ("KWP-2000") and ISO-15765
("CAN") protocols. Our interfaces do not
support the SAE J1850-VPW and J1850-PWM protocols used by most
US-market GM and Ford products, so this cannot work on those cars.
Most early (1996-2000) OBD-II compatible Chrysler cars used
ISO-9141-2. Many newer Chrysler cars use SAE-J1850 and
are incompatible. Most European and Asian
cars use ISO and should be compatible. In US
models, Generic OBD-II compatiblilty was required as of model year
1996. In Canada, 1998. In the European
Market, 2001 (gasoline-powered) and 2004 (diesel-powered).
Interfaces:
Our HEX+CAN interfaces support ISO 9141-2 ("CARB"), ISO 14230
("KWP-2000") and ISO-15765 ("CAN") protocols. Our non-CAN HEX-,
KEY-, and KII- series interfaces support ISO 9141-2 ("CARB"), ISO
14230 ("KWP-2000"), but do not support ISO-15765 ("CAN").
Our Micro-CAN interface support ISO-15765 ("CAN"), but do not
support ISO 9141-2 ("CARB") or ISO 14230 ("KWP-2000") for generic
OBD-II. The ISO-15765 ("CAN") protocol was introduced in a few cars
in model year 2004 and became universally required in all cars sold
in the US market for model year 2008.
