2018 2500 cummins electrical problems

[Curtis Wilbourn]

I am new to the forum so go easy on me I have a 2018 cummins 2500 crew cab 4x4 with a problem the dealership and I can't figure out. when it starts the park sense unavailable service required comes on the message center display along with the tire pressure light flashing on and off. then the service traction control and abs light pulses the emergency brake light flashes and most recent service antilock brack system and service electronic brake system it also has the oil light on then low oil pressure comes on the message center I've checked all the fuses and ensured that they were pressed completely down along with the relays I've taken it to two different dealers and they both state that they cannot duplicate the problem yet a couple of days after I pick it up it starts it again. any help would be appreciated. I have a video but it won't let me load it. I can email it to someone if they think they can help.

Reach out to @RamCares on this forum to see if they can open a case for you.

I'm not an expert but I suspect a Body Control Module (BCM) problem is the culprit.

Also, some of these electrical gremlins can be caused by a failing battery. I'd get it load tested to make sure it is up to spec.

I know this is an older thread but any chance you found a resolution? My 2018 with 46k is doing the exact same thing with every sensor flashing. My dash flickers on and off. Sometimes the tach will quit registering while driving. OBD port is also shutting off.

Brand new batteries installed, checked every ground I could find, clean,etc at the recommendation of diesel shop. Still no change.

your issue is not quite as bad as what is happening with some other Cummings powered Rams
They are shutting off at speeds over 25 mph
