When we are driving down the freeway, and we drive over the uneven parts of the road, the jarring motion trips the ABS warning light-Sounds off the warning bell-Displays the Traction Control warning light-and auto locks the doors all at the same time. This problem is only caused by jarring the vehicle on uneven road... such as driving into a driveway, or driving over a bridge transition on the freeway where the road elevation changes.
Either abs sensor failing or damaged and or hub failing the abs system is incorporated into the hub have vehicle scanned most auto stores offer this service for free

leaking suspension air bags is the most common cause, but the system can be tested for trouble codes, I suggest u do so, only the dealer can do this, but guessing about what the problem is can get very expensive very fast.

you have to fix the problem with ur brakes- first check the wiring ,connectors and connection clips to the abs sensors and modulator if looks ok than have truck scanned some auto stores such as auto zone / advanced auto do it for free the code will give u a start point towards fixing ur problem--visual inspection of brakes doesnt always show problem
