Suggest reading multiple posts from this forum before sinking big $. I have had warning light central twice. This forum and many folks responding saved me big (Colo disco and Victory Overland gave me great advice amongst others). Soon after getting my vehicle (2yrs ago) I had had issues and I replaced the battery and all went well and back to normal. Second time (recent, like within 30 days) was post hard off roading and it was the alignment.
Btw, I got list from stealer for $4000 of stuff but I am working on most of this on my own for 25% of the cost. Those morons forgot to reset my steering angle sensor after an alignment after I replaced tie rods and all sway bar bushings for under $150 and 2 Saturday afternoons in my garage. I was embarrassed for them, but I can tell you it was fun to tell them exactly what they screwed up and be right.
If you got the bong, special programs fault, ride height only fault ... I'd start with dealer alignment $140 - make sure they reset steering angle sensor. If you get code reader, the gap BT one is sweet. I got for Christmas. Armed with codes, folks here or some good research is going to answer a lot of questions quickly.
Good luck - 50 folks on this site have done this
