When USB programming the radio (RPO IVD) on some 2023 Colorado, Canyon; 2023-2024 LYRIQ; and 2024 XT4, Blazer EV and Silverado EV models (Fig. 8), a message may display that programming is currently unavailable. The message may appear due to a routine check of the 12-volt battery state of charge before USB programming begins.

To allow USB programming, a file can be created that will prevent the check of the battery state of charge. (Fig. 9)

After downloading the available USB file transfer for the radio from SPS 2 to a USB drive (16 GB or 32 GB Type-C USB drive formatted to FAT32), a new text document should be created on the USB drive to ignore the battery check. (Fig. 10)
Refer to the latest version of #PIT6047 for the complete procedure to create the file on the USB drive.

Once the file is created, the USB drive can be ejected from the PC and connected to the vehicle to proceed with USB programming.
A software update to address the battery check condition during USB programming is currently being developed. The battery check condition does not affect OTA updates.
