The internal program (firmware) inside all Ultium devices can be updated via MR. After a software upgrade, the user will be notified if an update to the firmware is required with a message that appears before measurement.
To check whether there is an update available, navigate to the Hardware Setup, then open the settings for the Ultium device by double-clicking on the Ultium icon.
NOTE: There are two updates typically required. The first “Update Now” button updates the Ultium receiver firmware. After the Ultium receiver firmware is updated, a second button will appear — “Update Sensors.” Both updates should be performed to update the receiver firmware and the sensor firmware.
When the firmware update is initiated, the Ultium receiver should be plugged into the computer via USB, and the sensors should be in the charging stations, connected to the receiver, and powered ON.
For more information on device setup or firmware updates after a software upgrade, review the relevant user manual for your device.
