If a 2017 Tacoma's cruise control is not working, what must be checked first?

If Your 2017 Toyota Tacomas cruise control is not working You should first check Your fuses and if those are good I would then consider a bad speed sensor. Auto parts stores such as Advance Auto Parts and Auto Zone carry any fuses that You may need for Your car. Changing the fuse is a simple task. You can tell if the fuse has blown by looking at the filaments visible in its little window. Before You open or work on a fuse box, be sure that Your vehicles ignition is turned off. Since the transmission speed sensors monitor the input and output shaft speed, it also plays a part in monitoring the cruise control.
