I recently bought a new truck. 06 Chevy silverado 8.1L. Anyways on the 6 hour drive home from buying it the freeway was going through some construction and was really rough. Not horrible but at 80mph it was rough. Every once in awhile when I would hit a jaring type bump my cruise control would kick off and my ABS light would come on. Idk If they were hand in hand but it seemed like it. One time the cruise control did it without the ABS light popping on. It happened 4 times in a 6 hour drive. Not a ton but annoying.

The abs light hasn't kicked on since I've been home. But I've only drove it 40 miles since I've been back. The Cruise Control still keeps kicking off with small to very light bumps. And alot more now then before.

Any ideas? Maybe it But I'd like to figure it out since i always use my Cruise Control. It does have a trailer brake controller If that matters. Maybe loose wiring? Help is appreciated!

if the abs system is active the cruise control is disabled.

post the code set in chassis for the abs.

fix the abs problem and your cruise control will operate normally.
