I have a 2020 RAM 2500 6.7 Laramie, and a P2609 code just popped up the other week. I cleared the code after finding out about the "wiggle" test. None of the lines going to the battery or solenoid look corroded or broken. After I cleared the code, I tried remote starting my truck in the morning and it wouldn't turn over and threw the same code. Is this something that still occurs regularly to 5th gens? Is the Banks Monster Ram the only option for this fix? I feel nervous driving my truck after seeing the "killer bolt" posts and whatnot. In the meantime I have cleared the code and bypassed the diesel preheat process by basically double pressing my ignition. Am I doing damage to my truck by doing this somehow? I live in AZ by the way and I don't even need a grid heater. Any advice would be much appreciated. Thank you!
