3.7 Vehicle Coverage
The Veepeak VP39 OBDII/EOBD Scanner is specially designed to work with all OBD II
compliant vehicles, including those equipped with latest CAN protocol -- Control Area
Network. 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.
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.
Different countries start to enforce OBD2 compliance in different years. For Canada, the
year is 1998. And for European Union (EOBD), it's 2001 for gas and 2004 for diesel.
Check with your local authority if you are in other regions.
4. OBD II Diagnostics
When more than one vehicle control module is detected by thescan tool, you will be
prompted to select the module where thedata may be retrieved. The most often to be
selected are thePowertrain 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.
» Verify that the ignition is ON;
» Check if the code reader's OBD II connector is securely connected to the vehicle's DLC;
» Verify that the vehicle is OBD2 compliant;
» Turn the ignition off and wait for about 10 seconds. Turn the ignition back to on and
repeat the procedure from step 5.
» If the "LINKING ERROR" message does not go away, then there might be problems for
the code reader to communicate with the vehicle. Contact your local distributor or the
