Re: 2000 4.8 Yukon ABS Module
Just got off phone with GMC Service Advisor. He says he doubts problem is my ABS Module stating that once that goes bad, my lights would stay on all the time. In my case, the lights come on intermittently and then stay on until I turn the engine off. When I re-start, the lights might not come on at all, within 3 minutes or after 15 minutes of driving. Those dang lights actually started showing 1 year ago but problem went away for 9 months before resurfacing the last 2 weeks.
He also said he thinks it is only a 25% chance problem is ABS and much bigger chance that it is a speed sensor problem in one of my wheels but wouldn't know until pulling the codes and doing an inspection.
Thoughts? What are wheel speed sensors?
