The vehicle gateway (GTW) detects the vehicle is configured as an Engineering Buck (eBuck), a setting intended for development purposes only and not available once the car computer is production-fused. If this alert is present on a production vehicle after delivery, service is required to production-fuse the car computer. A production vehicle should not be driven until the car computer is production-fused and the eBuck configuration is removed, as vehicle speed and torque will be limited.
|
The GTW detects the vehicle is configured as an eBuck, a development setting, which can only occur if the car computer has not been production-fused.
|
Vehicle speed and torque are limited, making the vehicle unsuitable for operation on public streets. It is strongly recommended, due to limited speed / torque, that a vehicle in this condition not be driven.

One or more of the messages the vehicle Gateway (GTW) receives periodically from the Tegra chip in the instrument cluster (IC) is not received through the ethernet connection, indicating the Tegra chip may be unavailable (MIA). This alert is only applicable to vehicles equipped with Info-Tegra Infotainment hardware.
|
One or more of the expected messages from the Tegra chip is not received.
|
The instrument cluster may be blank or may not function as expected.

|
The vehicle gateway (GTW) is updating the software of an offboard charger, such as a mobile connector (UMC) or wall connector. These updates run when the vehicle has finished charging and the user is not interacting with it (prior to the vehicle going to sleep). Disconnecting the charge cable will abort the update process. If the update is incomplete, the vehicle will attempt to update the offboard charger again later when all update conditions are again met.
|
The GTW detects an offboard charger software update is in progress.
|
Vehicle will be unable to drive or charge while the offboard charger software update is in progress.
