Over the Air (OTA) Programming

Over the air module updates are released from the Ford cloud and are received by the vehicle TCU over the vehicle cellular and WiFi connection. The TCU transfers the data to the GWM where it is distributed to the modules requiring the update. The over the air (OTA) updates are communicated between the GWM and the receiving modules through the Ethernet network, for modules with an Ethernet connection and the vehicle Controller Area Networks, for all other modules. There are 2 general types of update; Scheduled updates and Non Scheduled updates. The type of over the air (OTA) update required is determined by the type of update being released and the configuration of the module(s) being updated.

Additionally, there are a number of over the air (OTA) update sub types as described below.

• Simple: These are update releases that generally affect a single module.
• Coordinated: These are update releases that affect a number of modules and each module needs to be updated in a specific order.
