I have a 2020 Silverado lm2 with an engine light on. Codes are u 01b0 and u1345. I’ve tried resetting it with scan tool and disconnecting the battery for a couple hours but code does not go away. Scan tool says they are permanent codes and is unable to reset. Code came on after I popped the hood when the truck was running on remote start. Truck shut off right away when I popped the hood and CEL came on, on next start up. Went to dealership thought it would be under warranty apparently not. Dealership did not find any issues but wanted to change out the battery sensor but I chose to fix that myself. Codes still on. So id like to clear the codes to see if codes will come back before I return to the mechanic. Thanks for any help in advance.
