Truck is a 2017 Ram Rebel 1500 5.7 4x4 with around 81k miles.
While driving in light rain on the interstate at roughly 60 mph, I just had 3 service warnings come on all at once.
"Service Trailer Brake System"
"Service Air Suspension System"
"Service Electronic Braking System"
The air suspension is 'locked' in aero mode, the cruise control is disabled, and the traction control light is illuminated on the dash.
I checked the fuse box under the hood on the driver's side. All the fuses are good and I don't see any signs of corrosion. I then did a 'reboot' by disconnecting the battery for >1 hour and then reconnecting and taking it in for an OBD-II scan at O'Reilly. On the way there, all of the service messages went away and the accompanying symptoms disappeared. I still had them scan it to see if there was any stored codes of which we did not find any.
This 'solved' the problem for 6 days..
After the problem reemerged with all the accompanying symptoms, I did a OBD-II scan (with my newly acquired scanner :c) which produced no fault codes even though I was getting the service messages on the dash. I checked my battery voltage with the truck cold which showed 12.11 volts. With the truck running, I was getting a reading of 14.7 volts while at idle, and while driving, (including freeway speeds). I have since replaced the +4 year old original battery with a Odyssey AGM 94RH7L4 thinking maybe a dying battery was causing the faults as Ram trucks are known to do.
Any ideas what would cause all three service warnings to come on at once? Also looking for advise on the next step to take and/or a similar situation and what the fix was.
Thanks!
