|
No
|
|
|
One or more of the messages the Autopilot electronic control unit (ECU) receives periodically from the radar ECU is not received, indicating the radar ECU may be unavailable (MIA).
|
One or more of the expected messages from the radar ECU is not received. Alert log signal data should provide more information on specific message(s) missing.

|
No
|
|
|
Autopilot was aborted from active state, causing Autopilot features to disengage.
|
Autopilot was aborted due to Autosteer criteria needed to provide active control of the vehicle no longer being fulfilled. Alert log signal data should indicate reason(s) for Autopilot aborting.
|
Autopilot is disengaged.
|
No
|
|
|
The Autopilot electronic control unit (ECU) has detected that the steering angle rate requested by the Autopilot system is greater than the maximum allowed steering wheel angle rate. This may occur when driving at high speeds on roads with steep curves. Autopilot functionality will be temporarily limited.
|
While Autosteer is activated, this alert is active if the vehicle's current steering angle rate is greater than the maximum road wheel angle rate over the last 250 milliseconds.
|
The User Interface (UI) will notify the driver of a temporary reduction in Autopilot functionality, and Autopilot functionality will be limited.
|
No
|
|
|
Steering angle requested by the Autopilot system exceeds the permissible steering angle, leading to Autopilot disengaging and a chime sounding via the User Interface (UI).
|
The steering angle control requested by the control algorithm is greater than the maximum permissible steering angle at that speed.
|
Autosteer is temporarily unavailable, and a chime is played through the User Interface (UI).

|
One or more of the messages the Autopilot electronic control unit (ECU) receives periodically from the Steering Column Control Module (SCCM) ECU is not received, indicating the SCCM ECU may be unavailable (MIA).
|
One or more of the expected messages from the SCCM ECU is not received.
|
Autopilot features that require messages from the SCCM, such as Autosteer and Autopark, may be limited or unavailable.
|
No
|
|
|
