2012 TRD 2nd Gen in limp mode

Thank you for the welcome and the forum. My wife and I moved up to Iron county Wisconsin in '22. Winter can last about 6 months here so we traded the Malibu in for a 2012 Tundra TRD and installed a snowplow. I went around and around searching for a parasitic voltage draw last year. I had no luck trouble shooting the on the fuse panel a couple differant ways, I took it back to the guy that installed the plow, maybe that had something to do with it. Turned out the spare tire was oem and not holding pressure. I still put a battery tender on it.
Well now comes to why I'm here. After plowing about 5-6" of very heavy wet snow the truck went into limp mode. I put a Blue Driver scanner on it. Here are the codes that came up, Electric Motor Power Steering C1547 Vehicle Speed Sencor, Antilock Brake System C1201 Engine Control System Malfunction, C1241 Low or High Power Supply Voltage. I don't think its the C1241 code since the battery and terminals nice and clean. I tried doing a search with no luck. Not sure if I'm doing it right. Any assistance would be really appreciated.
