This model T69 OBDII/EOBD Scanner is specially designed to work with
all OBD II compliant vehicles, including those equi pped with next-generation
protocol -- Control Area Network (CAN). It is required by EPA that all 1996
and newer vehicles (cars and lig ht trucks) sold in the United States must
be OBD II compliant and this includes all Domestic, Asian and European
vehicles.
A small number of 1994 and 1995 model year gasoline vehicles are OBD
II compliant. To verify if a 1994 or 1995 vehicle is OBD II compliant, check
the Vehicle Emissions Control Information (VECI) Label which is located
under the hood or by the radiator of most vehicles.If the vehicle is OBD II
compliant, the label will designate
OBDII Certified”. Additionally, Government regulations mandate that all
OBDII compliant vehicles must have a “common” sixteen-pin Data Link
Connector (DLC).
For your vehicle to be OBD II compliant it must have a 16-pin DLC
(Data Link Connector) under the dash and the Vehicle Emission Control
Information Label must state that the vehicle is OBD II compliant.
