3.7 Vehicle Coverage
The OBDII/EOBD Code Reader is specially designed to work with all OBD II compliant vehicles,
including those equipped with the next-generation protocol -- Control Area Network (CAN).
It is required by EPA that all 1996 and newer vehicles (cars and light 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 "OBD II Certified". Additionally, Government
regulations mandate that all OBD II 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.
4. OBD II Diagnostics
When more than one vehicle control module is detected by the scan tool, you will be prompted to
select the module where the data may be retrieved.
The most often to be selected are the Powertrain Control Module [PCM] and Transmission Control
Module [TCM]. CAUTION: Don't connect or disconnect any test equipment with ignition on or engine
running.
1) Turn the ignition off.
2) Locate the vehicle's 16-pin Data Link Connector (DLC).
3) Plug into the OBDII cable to the vehicle's DLC.
4) Turn the ignition on. Engine can be off or running.
5) Press ENTER/EXIT button to enter Diagnostic Menu. A sequence of messages displaying the
OBD2 protocols will be observed on the display until the vehicle protocol is detected.
If the code reader fails to communicate with the vehicle's ECU (Engine Control Unit), a "LINKING
ERROR!" message shows up on the display.
