Battery light is always on.

RAM 1500 2015 1500/5.7 hemi/tradesman 120000 miles
I am trying to track down why the battery indicator light either is always on or it is on when you first fire up the truck in the morning and by mid day the light never comes back on. The voltage on the truck says it’s at 12-13 even with the battery light on and to me that seems like an okay operation. I have tracked down just about everything. New battery, replaced the radio, checked fuses and relays. Is there something I am missing???

This is how I fixed mine so on the fuse box in the very top left corner you’ll see like a screw that looks connected to the battery you’ll clean it up and you’ll also have to tighten it if it’s loose it’ll show the battery sensor issue
Raminator from United States a year ago
When u test the alternator it should read between 13-15 volts if ur getting 12-13 then u need an alternator these trucks will throw a battery light if ur within .05 volts off factory specs, there’s also a battery sensor on the battery u can check and a 250 amp fuse on the red terminal

Truck would not start. Battery was fully charged.

RAM 1500 2025 Bighorn 20000 miles
All the electronics were fine, when I pressed the start button, nothing would happen. After I sat in the truck with the door open I heard it go through its internal checks then I tried starting it again and it worked.

I had the same problem in my 2021 ram 1500... there is a inline fuse close to battery and the firewall that needs to be taken out and checked to see if blown. If not blown wait a minute then reinstall fuse and it should work.

I saw this. It is a reset of Uconnect, but may reset the head unit. https://youtube.com/shorts/47xG9DQQjeU…

Sometimes when you disconnect the battery or change the battery you got to reset the radio I'm not sure on how you do it check with the deal or ask them they might help you see if the mechanics walking around or something to ask them

The reason for the radio not working is when sometimes you disconnect the battery or change the battery and that's for thieves when they steal your radio it can't be used

Addium from United States a month ago
"Solved" is shown for this problem of the radio not working after battery replacement. What " solved" the problem?
I have had this happen on Jaguars in the past, and on a few other high end vehicles to thwart theft. Wasn't aware of it on a Dodge truck how ever. Call the dealership, and verify your vehicle has this anti-theft feature. If it does rust the code to unlock the radio. The VIN will be required, and possibly other information dependant on the dalership. Check the owners manual and accompanied paperwork a th 'code may have benefits recorded therein. This is for those who still are wondering what was does in your particular case that solved your problem.

You need to turn those knobs (bottom left corner that control interior lights) all the way left or if they’re already left, turn to the right.

Push button start not working trailer brake service code popping up

RAM 1500 2013 5.7 hemi  230000 miles
The push button start isn't working, it says that 'trailer brake service' is needed, also a code is flashing for 'four wheel drive needing service', But it won't actually turn over, won't even try and start. I push the brake in, then push the button to start it, and it'll turn the accessories on, I push the button again and it turns it to "run" but it doesn't actually start. The dash just flashes a couple times and then it turns it off.
I'm currently stuck in a parking lot so I'm definitely open to any advice, that being said I've tried...
•changing the brake light switch
•Changing the key fob battery
• doing a "hard reset"(disconnecting the battery for 20 minutes)
•jump starting it
•examine fuses for any obvious damaged ones

This happened to me too a few times...even the radio would stay on once the keys were out. Door was open. Car was totally off but the radio was still on. It was really weird so I turned it back on and did the whole thing over again. Shut it off after liShut it off after like 10 seconds. Open the door. Make so everything's shut off and it did. I guess it was just a glitch... as that happened last year and it hasn't happened since.

The metal contacts inside the remote are probably not making contact anymore. I had to replace my remote start key fob for that very reason. As soon as I popped the key fob open the metal contacts fell out. The contacts are usually held in place by some type of glue or adhesive that tends to just wear out over time from wear and tear. Replacing the battery won't help. You'll need to replace the key fob which cost me about $300 at the dealer ( $200 for the fob & $100 for them to program it). Hope this helps.

Won’t pass smog but no check engine light

RAM 1500 2010 Heli 5.7 105000 miles
Had all O2 sensors changed out and when it’s plugged in it reads O2 sensor not ready. We have reset the truck by pulling g cables off the battery then driving it for 500-1000 miles and tried to do the constant driving pattern that is mentioned for the test to get the O2 sensors reading and nothing has worked. Could use any other ideas. Thank you

The gaskets in the valve cover and the oil filter housing had blew. I replaced the gaskets. Now I’m having problems with the starter solenoid relay which is reading a 2 or higher volts when the truck is turned off. Idk what to do because my pcm is also not getting any power when I use the light tester.
