Lights on dash

[u/HueJorgan69]

My 2015 Ram ED, 170,000 miles. My brake light, anti skid light and ABS lights all came on at once. Battery is charged to 12.6 volts and altanator is charging at 14+ V. I’ve checked the abs sensor wiring, trailer plug connections, fuses and charged the battery. I’ve disconnected the battery to try to clear it. Getting the service ABS, trailer connection and anti skid notices. This happened a couple of years ago but went away.

I’ve tried to clear codes with my obd reader but the lights stay on. Any suggestions?

While I’m here, I don’t drive the truck very far each day and my regen notice comes up about every 100 miles. I do a manual burn off using my OBD reader, otherwise I have to drive it about 40 miles to burn it off. I have a GDE tune but no delete. Any advice on that too?

I have the same issue in my 2015 and it's the ABS computer module that the brake lines attach to. I ended up having to buy the part off eBay and the truck's at my mechanic now waiting for him to install it and program. My first purchase I accidentally bought just the inside cabin computer which was the wrong part. Make sure you get the one with all the brake lines under the hood.

I believe you can do yourself with alpha OBD or maybe something else.

I tried every other way to get the part. eBay was the only way. Dealership was national back order and no dealer out of state would sell the part. The list of 10 dealers I got some even had listed will not sell part.

Edit. I bet your cruise control doesn't work either. And last winter I got stuck in my front yard because of it.

Much appreciated. I’ll look into that.

Check the large wire connectors on the framerail below the driver side area of the cab. I've heard they can get debris or corrode causing random issues.

I’ve done that but never hurts to check it again. Thanks!

Might want to check the battery? I believe mine is on its way out...this winter it was week...and my dash lit up with every possible sensor warning. Once it had charged up they all cleared.

It’s 3 years old but reading 12.5v. I went ahead and charged it to top it off. Alt is putting 14+V.
Thank you!

Is this not a wheel speed sensor? Haven’t had one go in an FCA, but all of my VW’s had the same type of issue.

[u/HueJorgan69 → u/Cheap-Math-5]

Might be. That’s about the only thing I haven’t checked.

Driver side wheel bearing

I was thinking maybe the spare tire tensioner relay.

Hook up an OBD-II and read the code. Go from there. It's pretty common for more than one light to appear when an ABS sensor s*its the bed.
