Maintenance/Repairs

I have a 2008 Silverado 1500 WT with the V-6. It has approximately 161000 miles. I don’t drive it much, only put about 30000 on it in the last 3 years that I have owned it. Last month, I noticed the ABS light on during a trip to town. The following day, it went out. Two days ago, I was using my truck on a job and was sitting parked with the engine idling. The ABS light came on again and the warning chyme also sounded. While looking at the instrument panel, I noticed that while sitting with the transmission in park idling, the speedometer would bounce sporadically from 0-10mph. Can I assume that the two are related issues and if so, where do I start looking? Thanks in advance.
