Condition
Some customers may experience a no crank due to a low or dead battery.
Cause
The cause of this concern could be a failed Over The Air (OTA) update.
Correction:
Please read the following procedure one time to get familiar with the steps prior to performing the procedure
below.
Charge the battery and test using the GR8 or DCBS to make sure the battery is good. After the battery is
recovered, check the radio/infotainment update menu for a pending update. If the update shows download
paused, example shown above, then the dead battery was the result of the OTA event failing in the Serial Data
Gateway Module (SDGM).
To recover the SDGM: (Read all instructions before starting the procedure)
