I have 2 Dodge Rams 1998 1/2 ton Sport 4x4 5.2l and 2006 2500 4x4 5.9 diesel. On the 98 the ABS and brake lights come on when started and stay on until engine is shut off. This happens every 3rd or 4th times I run it. Have change the rear sensor and it did not fix the problem. It only has ABS to rear wheels. On the 2006 2500 I get a ding sound and the ABS brake light comes on for a second when I turn a sharp corner. I suspect a short on one of the front wheels since it has ABS sensor on all 4 wheels. The 1998 has 234,000 miles on it and the 2006 has 61,000. Just recently started on my 2006. Tom
