Link Errors or Erroneous Data

If the Code Scanner displays link errors when attempting to
read, erase, or look up codes, check the following:
Make sure the cable is securely connected to the DLC.
Verify ignition key is ON and not in the ACCESSORIES
position.
Examine the DLC closely and check for cracked or recessed pins, or for any sub-
stance that could prevent a good electrical connection.
Verify that the vehicle you are testing is an OBD II compliant vehicle. Just because it
has the OBD II J1962 DLC does not mean the vehicle is OBD II compliant.
Test for continuity between the DLC wiring and the PCM. In an extreme case there
may be a broken wire.
Check the vehicle for blown fuses. If the PCM fuse is blown, it cannot transmit data.
NOTE: The PCM fuse may be located on the fuse block in the passenger compart-
ment.
Make sure the PCM has a good ground. If the PCM has a ground directly to the case,
clean the connection and apply a conductive grease to the mating surfaces.
As a last resort, the PCM may be defective. Refer to the vehicle service manual for
correct procedures for testing the PCM.
If the Code Scanner is not working correctly after the checks and corrections above,
contact the technical support line at 1-800-228-7667 (8:00 - 6:00 EST Monday - Friday),
