3.7 Vehicle Coverage
The CEOBD 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).
A small number of 1994 and 1995 model year petrol powered 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 bonnet 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 elected are the Powertrain Control
Module (PCM) and Transmission Control Module (TCM).
CAUTION:
Don’t connect or disconnect any test equipment with the
ignition on or the engine running .
1) Turn the ignition off.
2) Locate the
vehicle’s16-pin Data Link Connector (DLC).
3) Plug into the Scan Tool cable connector to the DLC.
4) Turn the engine on. Engine can be off or running.
5) Press ENTER/EXIT button to enter the Diagnostic menu. A
sequence of messages displaying the OBDII protocols will be
observed on the display until the vehicle protocol is detected.
If the code reader fails to communicate with the vehicles ECU
(Engine Control Unit), a “
LINKING ERROR!”
message shows up on
the display.
6)
Verify that the ignition is ON. Check that the code reader’s OBDII
connector is securely connected to the vehicle’s DLC.
7) Verify that the vehicle is OBDII compliant: Turn the ignition off and
wait for about 10 seconds. Turn the ignition back on and repeat the
procedure from step 5.
If the “
LINKING ERROR!”
message does not disappear, there may
be problems preventing the code reader communicating with the
vehicle. Contact your local dealer for assistance.
