Thanks for your response.
First, the scanner is brand new. This is the first time it has been used. Second, the sticker/placard under the hood states: "OBD II Certified."
To offer some additional background, this particular code/problem was read successfully by both the OBD II reader at AutoZone and another unit at a repair shop. My reader, unfortunately, continues to give a "No Link" response, even though I know the reader functions because it successfully linked-up with the computer on two other vehicles and stated "0 Codes" instead of the "No Link" error.
