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 SCROLL button to select OBDII/EOBD
from the Main Screen (Figure 2-2).
6） Press the OK button and wait for the Menu to appear. A sequence of
messages displaying the OBDII protocols will be observed on the
display until the vehicle protocol is detected.
 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 OBDII cable is securely connected to the
vehicle’s DLC.
 Verify that the vehicle is OBDII 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.
