3 OBD II 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) Use the SCROLL button to select OBD II/EOBD from the Main Screen
in the scan tool.
6) Press the ENTER/Exit 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.
7) View a summary of system status (MIL status, DTC counts, Monitor
status) on screen. Wait a moment or press any key for Diagnostic
Menu to display.
