Parking brake light on dash comes on while driving 2006 dodge ram 2500 5.7

I need some direction.  My parking brake light comes on while driving.  When I connected my maxisys to my truck it said nothing of any code related to e-brakes.  Master cylinder looks good no leaks and has plenty of fluid.  Need some direction. Diyer here.  Thanks

No codes in the ABS for low fluid level? I know you checked the level, but that doesn't mean there isn't a circuit fault.

I'd also look at the parking brake switch circuit, and the parking brake pedal switch itself. You could start by disconnecting the parking brake switch and drive it again. If the light now stays off, investigate the pedal further.

No codes in the abs system.
I will check the brake pedal switch next. I don’t have a wiring diagram yet. But I will check for power, ground and signal wire. I’ll figure out what type of switch input I have after unplugging the connector. Thanks Tyler.

 this is what my autel reported it.  
circuit is a pull down switch input.
test light to ground and it pulled it down to ground no problem.  circuit is good.
