2020 limited P0DAF code

[Hoosierlimited]

Long story short, truck is a 2020 limited with the etorque hemi. Check engine light came on last night and thought it was due to putting the S&B cold air on... Pulled the single check engine code and it was the P0DAF leading me to think problems with the 48v charging system.

Earlier this winter my main battery went bad in the truck which I replaced. Wondering if I should clear the code and see if it comes back or call the dealer now for a service appointment. So far no issues with battery voltage.

Have you found the solution to this code? my 2019 Bighorn etorque just popped this P0DAF code out of no where. Same issue too, I replaced the battery in march due to another code that came on in regards to the traction control and transmission. I dont know what do about this one though. Seems like it cant be the main battery again, unless its just no good

Haven't had a chance to drop my truck off to the dealer yet (wife's car is getting a warranty transmission) but I had the code pop up again twice about 2 weeks apart and low voltage once.

Starting to believe the main hybrid battery pack is going bad from I read around other sources and it takes a couple days of testing for the dealership to test it out.

Yea theres not much info on it out there. Have you had any driving issues with the light on the past few months? How many miles would you say? Im concerned because I have a long road trip coming at the end of the month. When you reset how long will it stay off? It seems like mine will be off for about a day and then come on with the same code. I was thinking maybe try to exchange the main battery first. Ironic that we are both having the same issue shortly after replacing the main battery

No drivability issues, actually drove my truck from Indiana to Colorado and back a couple weeks after it first came on. If my voltage is low on start up it goes right back to 14.3v fairly quick.

Just want to get the hybrid battery issue figured out before I'm out of warranty. Only reason I replaced my original battery was it wouldn't take a charge.

Most likely a battery pack. Code diag is clear it, does it come back? yes replace battery pack. There may be an update they will do 1st.

Has this issue returned? Battery light just started coming on then going off for a couple days only in the morning. Just started it up and was driving when the check engine light came on again with the same p0daf code. It had been fine since July. Voltage goes to 13.8-13.9 now.

Ever since I replaced the factory 12v battery I haven't had any issues. I know for the 19-20s there's a history of bad Mopar batteries only lasting a couple years. Haven't had the code return since last summer.

 

[daigua]

Originally had one of those short lived factory batteries, installed a new battery a year ago and no problems until recently with the P0DAF. Truck has been at the shop for over a week now, currently under going testing to see if the 48V battery can be replaced per the 8 year / 80k miles emissions warranty.

 

[Briencrotty]

Hey there Daigua, were you successful getting the 48v battery replaced under the emissions warranty? I just started having that same code pop up.

Thanks,

B

I just had this code pop up this weekend and then cleared it and came back today. No operational issues other then my battery voltage getting low when the truck was stopped at a red light with the engine off due to the start stop.

 

[Ellisstrong]

Anyone else had any issue with this P0DAF code. I have an appointment at the dealer for it next week now as I cleared it and it came right back. Battery voltage drops down to barely over 11 then goes right back up to 14.2-4 a few seconds later sporadically. It definitely seems like something isn’t working right with the etorque system/battery to me. Truck still drives the same and starts right up even with the drop in temps we are experiencing this week.

Did anyone ever figure out the reason behind the code P0DAF? My 2019 ram 1500 has had that code pop up 3 times in the last couple weeks. And I haven't been able to find anything online that shows what anyone has found that would cause the code. Any help would be greatly appreciated!

 

[Ellisstrong]

Mine definitely had something to do with the etorque battery pack if I remember right. By the time I got in to my appointment it had cleared and stopped acting up and the code needed to be active for them to get approval to fix anything with it.

 

[Ellisstrong]

Just had a check engine light pop up and this code is back again. Hadn’t had it since December of last year if I remember right.
