DESCRIPTION:
We have received reports where the software download has been interrupted and it is not possible to download the CEM. This can occur with the download of any software package.
This condition can occur during any software download.
SYMPTOM:
Software download is interrupted and CEM download failed message may be seen.
SERVICE:
Follow the recovery guidelines and CEM recovery method below.
1. ALWAYS ensure a battery charger is used when downloading software and that the voltage of the vehicle battery/charger does not fall below 10 Volts or go above 16 Volts at any time during the download. Voltage levels above 16 volts have been reported when using "booster type chargers" and this results in download failure.
2. Ensure the DiCE is updated to the most recent version of firmware.
3. Ensure that VIDA is upgraded with the latest patch. See Service Product Journals for VIDA/UPDATES

External power supply to the DiCE.
