|
|
|
The vehicle gateway (GTW) has not received an expected system status message from the secondary Electronic Power-Assisted Steering (EPAS3S) electronic control unit (ECU) via the controller area network (CAN) within the required time period, indicating the EPAS3S ECU may be unavailable and power steering may be limited or unavailable.
|
The GTW does not receive the system status CAN message from EPAS3S ECU during 5 consecutive message cycles (for 50ms) while the vehicle is in Drive.
|
Power steering and Autopilot features depending on EPAS3S, including Autosteer, may be limited or unavailable.

|
|
|
The vehicle gateway (GTW) is cycling power (off, then on again) to the infotainment processor and touchscreen (UI) in response to user input via the steering wheel controls (a scroll-wheel reset request). This alert is primarily informational and for logging purposes.
|
The GTW detects a steering wheel controls (scroll-wheel) reset request.
|
A successful steering wheel controls (scroll-wheel) reset reboots infotainment features / components, including the touchscreen and car computer (may vary based on vehicle platform / infotainment system). This alert is intended to log the reset request and does not indicate any expected impact on vehicle functionality.

|
|
The vehicle gateway (GTW) detects that at least one electronic control unit (ECU) did not successfully install an update during an attempted vehicle software update. Version mismatch alerts should be present indicating any ECUs affected as the software they are running may now be incompatible with the software versions installed on other ECUs. The vehicle software update may also have aborted before changes were made to any ECUs.
|
The GTW Updater application does not successfully install updated software on every ECU during an attempted vehicle software update.
|
This alert is primarily informational and for logging purposes to indicate a vehicle software update did not install successfully on every expected ECU. No direct impact on vehicle functionality expected due to this alert, but it indicates the vehicle software update aborted or at least one ECU update did not succeed. Version mismatch alert(s) should be present to indicate any ECU not updated successfully.

|
|
Production security keys, which are used to validate vehicle software updates, have not been provisioned for the vehicle gateway (GTW). Production security keys are normally provisioned when the car computer is production-fused, so another alert may be present indicating the car computer and GTW need to be production-fused.
|
Production security keys have not been provisioned for the GTW.
|
The car computer and GTW are vulnerable to security risks, and the vehicle is unable to validate and install production vehicle software updates.
|
|
|
The vehicle gateway (GTW) has reset unexpectedly due to an internal error (exception to normal operation). May occur due to either software or hardware conditions affecting GTW function.
|
An exception to normal GTW function occurs, causing the GTW to reboot unexpectedly. Alert log signal data should provide more information.
|
Features depending on GTW functionality may be limited or unavailable while the GTW reboots. Vehicle may enter limp mode, with other alerts present to indicate this condition if it occurs.
|
|
|
The vehicle gateway (GTW) detects the PARTY controller area network (CAN) bus is not functioning as expected, making communication over the PARTY CAN bus limited or unavailable.
|
The GTW detects a condition limiting or interrupting communication over the PARTY CAN bus.
|
Communication over the PARTY CAN bus may be limited or unavailable.
|
|
|
The vehicle gateway (GTW) detects the Chassis (CH) controller area network (CAN) bus is not functioning as expected, making communication over the CH CAN bus limited or unavailable.
|
The GTW detects a condition limiting or interrupting communication over the CH CAN bus.
|
Communication over the CH CAN bus may be limited or unavailable.
|
|
|
The vehicle gateway (GTW) detects the Vehicle (VEH) controller area network (CAN) bus is not functioning as expected, making communication over the VEH CAN bus limited or unavailable.
|
The GTW detects a condition limiting or interrupting communication over the VEH CAN bus.
|
Communication over the VEH CAN bus may be limited or unavailable.
|
|
|
The vehicle gateway (GTW) is not production-fused, which normally occurs prior to customer delivery. Service is required to production-fuse the GTW.
|
The GTW on a production vehicle is not production-fused.
|
The GTW is vulnerable to security risks.
|
|
|
The vehicle gateway (GTW) is in Factory Mode. Service is required to production-fuse and factory-gate the GTW, which normally occurs prior to customer delivery.
|
The GTW is not production-fused and factory-gated.
|
The GTW is vulnerable to security risks. Vehicle will be limited to speeds too low (3-5mph) for operation on public streets.

The vehicle gateway (GTW) detects the front Oil Pump Controller (OPCF) electronic control unit (ECU) is running a firmware version that may not be compatible with the firmware installed on the rest of the vehicle.
|
The GTW detects the OPCF ECU running a different firmware version than expected.
|
Features depending on front oil pump functionality may be limited or unavailable. Inability to use waste heat to supplement high voltage battery heating may make charging at colder temperatures limited or unavailable.
