4 OBDII Diagnostics
When more than one vehicle control module is detected by the scan tool,
you will be prompted to select the module with retrievable data. The Power
train Control Module [PCM] and Transmission Control Module [TCM] are
the most commonly scanned modules.
CAUTION: Don’t connect or disconnect the scan tool while the ignition is on
or the engine running.
1) Turn the ignition off.
2) Locate the vehicle’s 16-pin Data Link Connector (DLC).
3) Plug the tool into the vehicle’s DLC.
4) Turn the ignition on. Engine can be off or running.
5) Turn on the scan tool. Use the UP/DOWN scroll button to select
OBDII/EOBD from the Main Screen.
6) Press the OK button to wait for the Menu to display. The tool will
display OBDII protocols until it has detected the vehicle’s
communication protocol.
 If the scan tool fails to communicate with the vehicle’s ECU
(Engine Control Unit) more than three times, a “LINKING ERROR!”
message displays on the tool.
 Verify the ignition is ON;
 Check if the scan tool’s OBD II cable is securely connected to the
vehicle’s DLC;
 Verify that the vehicle is OBD II compliant;
 Turn the ignition off and wait for about 10 seconds. Turn the
ignition back on and repeat step 5.
 If the “LINKING ERROR” message continues to display, contact
your local distributor or customer service for assistance.
