CAUTION: Don’t connect or disconnect any test equipment with
the ignition on, or with the engine running.
1) Turn the engine off.
2) Locate the vehicle’s 16-pin Data Link Connector (DLC).

displaying the OBDII protocols will be observed on the display until the vehicle

If the code reader fails to communicate with the vehicle’s ECU (Engine

- 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 OBDII 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, there might be
problems communicating with the vehicle. Contact your local distributor or
the manufacturer’s customer service department for assistance.
