Security Gateway Module (SGW) Software Update Customers may experience one or more of the following:
• Connectivity services will not work - including WIFI setup, Alexa, live traffic etc. Level 2 Plus functionality also affected/not enabling.
• SGW not responding to diagnostic and showing offline. The following software enhancements are also available:
• Diagnostic Trouble Code (DTC) U3033-00 - Control Module Security Certificate Missing/Invalid and U3033-01 - Control Module Security Certificate Missing/Invalid - General Electrical Failure are both active or stored and cannot clear. This DTC will not turn on the Malfunction Indicator Light (MIL).
• If a Firmware Over The Air (FOTA) message appears specifically directing the customer to service OR repeated FOTA events are not being completed, then a manual flash is required for the SGW update. This bulletin involves inspecting and possibly flashing the SGW to the latest software level in the case that the FOTA did not function.
