ABS Light Due to Poor Electrical Ground Under the Battery Tray on Chevrolet Avalanche 1500

A poor electrical ground under the battery tray may cause the ABS warning light to illuminate. Our technicians tell us that cleaning and properly securing this ground and also the main ABS ground on the frame rail below the drivers door may be necessary.

When I go over bumps my ABS light come on and when I turn the truck off it goes off untill the next time I hit bumps in the road.
My ABS/Brake lights come on at some point after my truck is started. The DIC instructs to service brakes soon. There is nothing wrong with my brakes. I am hoping this is the problem and an easy fix!!

Lights come on and DIC indicates a problem "Service Brake System".
The ABS and Break light comes on and we cleaned the ground, but that did not work for more than a couple days. The light continues to come on, sometimes immediately, sometimes after 1+ hours of driving. If it is bumpy it seems to come on quickly. The problem persists.
