|
|
|
Air Compressor internal software fault detected.
|
Internal software fault detected reason in payload
|
Air Compressor stops running
|
|
|
Air Compressor internal software fault detected.
|
Internal software fault detected reason in payload
|
Air Compressor stops running
|
|
|
A electrical fault has been detected in the base amplifier.
|
A electrical fault has been detected in the base amplifier, possible causes include under-voltage, over-voltage, over-current, over-temperature, clock Phase-Locked Loop issues, or DC offset errors.
|
Compromised audio performance, signal degradation, or complete loss of audio functionality.
|
|
|
The Audio Digital Signal Processor (ADSP) version does not match the version reported on the main system-on-chip (SOC). Vehicle audio may not operate as expected.
|
Cyclical redundancy checks (CRCs) detect a version mismatch between the ADSP and main SOC.
|
The audio system may not operate as expected if there is a difference in features between the reported versions.
|
|
|
Air Compressor high voltage is below or above normal.
|
Battery voltage below 300V, or above 780V
|
Air Compressor stops running
|
|
|
Air Compressor low voltage is below or above normal.
|
Low voltage below 6.5V, or above 32.5V
|
Air Compressor stops running
|
|
|
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.
|
|
|
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.
|
|
|
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).
|
|
|
Air compressor has exceeded maximum motor temperature.
|
Motor temperature exceeds 110C
|
If motor temp continues to increase, compressor may stop producing air

|
One or more of the messages the Autopilot electronic control unit (ECU) receives periodically from the Electronic Stability Program (ESP) ECU is not received, indicating the ESP ECU may be unavailable (MIA).
|
One or more of the expected messages from the ESP ECU is not received.
|
Autopilot features are unavailable, GPS performance may be degraded due to lack of wheel tick data from ESP.
|
|
|
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.
|
|
|
One or more of the messages that the the Autopilot electronic control unit (ECU) receives periodically from the vehicle gateway (GTW) ECU is not received over the controller area network (CAN). Autopilot features will be unavailable, or may not function as expected.
|
The vehicle gateway (GTW) CarConfig and GTW chnm messages are not received by the Autopilot electronic control unit (ECU).
|
Autopilot features will be unavailable, or may not function as expected.
|
|
|
The Autopilot electronic control unit (ECU) has detected an error with message(s) received via controller area network (CAN), potentially reducing Autopilot functionality.
|
Received CAN message is too short / long, the checksum does not match, or unexpected sequence errors are present. The values exceed the predetermined threshold.
|
If critical controller area network (CAN) messages have unexpected errors, the Autopilot electronic control unit (ECU) could mark other ECUs as missing. This may cause Autopilot functions to be temporarily unavailable.
|
|
|
The driver has applied sufficient torque to the steering wheel to cancel Autosteer / Lateral Control (LC).
|
The Autopilot electronic control unit (ECU) receives a message that the driver has manually canceled Autosteer with the steering wheel.
|
This alert is for logging purposes only. The vehicle is operating as expected when the alert is present.
