You have to turn vehicle off then on to reset. Then go 30 ft and repeat
process.

This issue could be caused by a number of reasons. However, it could be just a speed sensor but we need to check for codes first and foremost.

Here are guides that help with this as well:

If you can't get codes, then most parts stores will be able to pull them free of charge. Let's start with this and go from there. Thanks
