Over-The-Air (OTA) Updates

WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

The IPC is capable of receiving software updates through a cellular or WiFi connection to the vehicle. The software updates are sent to the TCU and then to the enhanced central gateway (ECG), or GWM. The GWM sends the software update data to the IPC over the HS-CAN3 or through a pair of ethernet cable circuits connected to the IPC, depending upon the type of software update or IPC level. The ethernet cable connections are used for higher speed downloads and enhanced data security. The ethernet cables are color coded specifically for each module.

The ethernet connection is used for module software updates only, and not for receiving messaged data related to IPC function or driver information. If a module communication concern is detected, it will only affect the CAN connections to the IPC.

For certain types of software updates, certain vehicle functions will be unavailable while the updates are occurring, such as vehicle start, driving the vehicle, charging the vehicle (HEV) or using the key fob to lock or unlock the vehicle. The vehicle owner can schedule the software updates for periods of vehicle non-use, or cancel the update prior to the software download. The vehicle owner will also be notified when an update is ready to download.
