Cruise control light on

This means there is an issue with the system, and we need to start with checking for codes.

This could be as simple as a switch issue, but it could also be an open circuit in some of the wiring.

Once we know what codes are there, then we can figure out the next steps, but I am including the wiring diagram which includes all the components for us to start checking.

The most likely cause of this is an ECM or actuator issue but again, we need to start with codes to find out the correct testing to start with.

Let me know what you find, and we can go from there. Thanks
