02 2500hd 4x4. Throws both the abs and the brake light at the same time. It started randomly and now happens almost every time I drive it. I was finally able to get my Harbor Freight code reader to interface with the ABS module and received C0265, C0241, C0242, C0251, C0246, and C0252. As far as I can tell, there are failures in the front wheel sensors, one or more solenoid circuits, and a handful of "your pcm senses a problem codes."
At the moment, all codes were active. I cleaned them and rechecked several times since then, and the only code that has resurfaced is C0265. I'm guessing the others were ghosts in the machine. It appears that I will have to replace the module.
