Return to the dealer and ask for a refund. They've obviously incompetent and don't do quality work. Good Lord! That was your brake system that they worked on. Then find a shop that is competent.

Sorry just to clarify. The dealer put it on the computer to diagnose the problem and it came up Left front speed sensor fault. My Husband installed the sensor. Senseless to pay them $200 to plug it in. The tech said the lights would reset after so many starts or miles driven. But they never did. There is a pigtail between the sensor and the harness we could replace. The brake system seems to work fine. Just noticed the cruise not working today. Wondering if its linked to the other lights being on.

You need to clear the system, locate the main power distribution box under the hood, open it and find the main fuses for the engine control and the ABS, remove the main fuses, then check the fuse box in the cab, see if there is a fuse labeled KAM, if there is remove it, let the unit stand at least a few minutes, then reinstall the fuses, restart and see if the light stay out, if they come back on then you still have a failure in the system.

As for the C.C. Check your brake lights. If it just happened it's possible that the brake light switch went south. It's located down where the brake peddle connects down under in the foot well. The two are connected and and if the brake light switch is bad. No C.C.

So I have the same lights on mine the code shows back rear speed sensor.. So I replaced that along with the plug and wires for rear and the lights still come on
