Multiple codes on my used 2019 RAM 1500 Sport

[JJGray330]

Hello all,
I just bought a used 2019 RAM 1500 Sport with 59,000 miles on it. It was originally a Canadian truck. I bought it from a used car dealer in my area with great reviews. I have spent over a year shopping. I had an inspection done at my local CDJR dealership. The inspection went well as far as the mechanics of vehicle are concerned. The issue is there are a ton of stored codes for potential electrical issues. The codes are as follows: C2100-9a, B257-00, U01784-00, B2199-66, B154F-00, B1290-25, B128F-15, U 018-000, U0141-00, 40375 CP 1.00 180.00 180.00.

I'm wondering if anyone can shed some light on what all these codes are or if they have had similar experiences with their own 2019 RAM 1500 trucks. The dealership told me this could cost hundreds of dollars to diagnose and thousands to fix. Any thoughts? My initial thought was with the truck being from Canada, there is a high likelihood the battery died for the original owner, thus tripping the codes. That said, I have never owned a vehicle with all this technology packed into it. My previous car was a 2005 Toyota Highlander.

Any help would be greatly appreciated!

Half of the codes have to do with low voltage condition, some of them with door modules and crank signal waveform irregularities.
Some of them are not in DTC listing that I can see.
Disconnect the negative battery cable, let sit for an hour or so, see if any of the codes clear.
I would just go and install a new, fully charged battery from the start.
If that did not help then go after the 30 or so ground connections, making sure they were good and clean.
And if you are a DIY guy, then

Thanks for the info, did you get all the info for those codes from that site you shared? If so, how does that site work? Do I have to maintain a membership in order to access the information for the codes for my truck or can I print all that information out to keep on file at home? Lastly, in your opinion, are these stored codes something I should be worried about? I know 2019 was the first year for the Gen-5 RAM trucks so it's likely to have more issues than the later years. But I also see that you own a 2019 Rebel and would assume you don't have any issues.

Thanks again for everything, as it is greatly appreciated!

Yes, from the site.
You can get different subscriptions from monthly to year to 3 years. I renew every year, money well spent IMO.
Yes, you can print the info when subscribed.
If the codes are not effecting drive-ability then up to you.
My 2019 has had couple things happen, a poor ground connection killing the battery, cracked rear window frame, leaky CHMSL gasket, broken rear defrost and a broken exhaust manifold bolt.
Other than that, a solid and fun to drive hemi truck. So far...

By stored you mean historic? Or do you have a MIL light on with active faults?

Start with checking your battery connections. Then, make sure the battery is fully charged and have it tested. If all that passes then I would be looking into a bad ground or wiring harness that has rubbed through somewhere.


If all these are just historic, I would be thinking the battery was left sitting at low voltage and someone tried to fire it up/jump start.

Stored codes meaning diagnostic trouble codes (DTCs) that the car's computer has saved in its memory, indicating a persistent issue that has been detected multiple times over various driving cycles, essentially recording a history of problems even if the check engine light isn't currently illuminated; these codes can be read by a mechanic using a diagnostic scanner to diagnose potential issues with the vehicle. I was told all of those codes are popping up in the computer's memory when the dealership took a look at the vehicle. Personally, I am in agreement with you, to me it seems like the battery just died at some point and those codes never properly cleared. That said, I have heard the 2019's have electrical issues because they are the first year of the 5th generation. As far as I can tell, everything is in working order, so I'm not too terribly concerned at the moment.

Your truck radio will be programmed for cananda ... it may take dealer wizardry to switch the programming of the radio software to the US standards then, have the latest US software update installed. Open your wallet, and just get over the sticker shock. It will in the long run make your life easier as numerous functions are controlled via the radio software.

So yes being historic it is unlikely an issue. Without the most recent freeze frame data to see when the last timestamp was when the faults set it is hard to tell if any real issue exists. If they are “permanent” faults then it will take multiple drive cycles for them to clear themselves out of the ecm in the background so to speak. I would just run it unless warning lights or symptoms appear.
