Security Gateway Module (SGW) Software Update The following software enhancements are available:
• Update for Diagnostic Trouble Code (DTC) U3033-00 - Control Module Security Certificate Missing/Invalid. NOTE: This DTC will not turn on the Malfunction Indicator Light (MIL) but is active or stored and cannot clear.
• If a 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.
• SGW module is not responding to diagnostics and is showing offline. This bulletin involves inspecting and possibly updating the SGW to the latest software level in the case that the FOTA did not function.
