Hi. I just bought a newer truck a week ago and was running great. Then when I started tonight at work it ran rough and almost died. It straightened out by threw out these two codes, P2509 and P2149.
When it was running bad, my dash voltmeter was way down like eight volts. I checked out the batteries and they are 2006 MOPAR models that came with the truck from the factory! Amazing! Then is when I threw the codes and MIF light.
I checked out the connections on the batteries and three out of four I removed without a wrench. When I remove the first one the light under the hood went out which means only one battery was doing it all. I brushed them and used conductive battery grease on each connection. I'm charging them tonight.
Sorry for the length. Could bad batteries or connections cause these codes?
Where to look next if this didn't help? Thanks, Herb
