I assume you have properly tapped it to the VSS circuit, that said, hold both buttons at the same time til it says CAL, ignore anything else till it says that, it may be more than 10 seconds.. Then drive to your right in a very tight circle (full lock is best). I had to go 7 times till mine caught.
If yours still refuses to do that, I would suspect you're not tied into the VSS properly.
