Service Antilock Brake System

[Donna Streight]

This is my first post and I thank you for any help you can provide. I have a 2013 Dodge Ram 1500 with around 96k miles. Awhile back my Service Antilock Brake System light illuminated and caused my Ram to rev up horribly when going down the road. Several trips to the dealer and found out I needed front hubs/wheel bearings. I got those replaced. A couple months ago I got new tires installed and a week later the back drivers tire shows no air but figured it is a dummy gauge and didn't really worry about it. It always chimes "service tire pressure system on start up" and shows "--" for the tire pressure on that tire. I was coming home from town and the Service Antilock Brake System light chimed and kept going off. It first came on during a sharp left hand turn and then went off, I hit a bump in the road and it came back on and later went back off. Now it is back on and won't go off. I've taken it to O'Reilly and no codes pop up. I'm nervous it'll do the revving again. What should I do and where do I start? Thank you everyone!

When you say the engine revved up, what RPM did it go to when the ABS Light came on? Did the truck actually try to accelerate when this happened?

Before when it came on, it would rev up to 5k RPM at the most. I'd just be driving along and it'd rev up anytime the wheels were turning. The dash and headlights would also flicker. This time is different though - the ABS and Traction Control Light comes on with a message "Service Antilock Brake System". It'll come on and then go off or not come on at all or be on and stay on. So far it hasn't done the engine revving. We replaced the one tire TPMS today and $100 later that light is off but still having issues with the "Service Antilock Brake System". I did notice a lot of the time when it comes on is either when making a sharp turn, sitting at idle or when going over a big bump (pothole). I would really like to figure out what to do to get this light to go off for good because it startles me and I can't use cruise control. Appreciate it!

Just to confirm, is this a 2013 RAM 2500 with a 6.4 HEMI? Does this truck have a single rear wheel or a dual rear wheel?

I got confused when i looked at your bio on the left side of the screen. It shows your truck is a 6.4 HEMI.
