|
The Media Control Unit (MCU) detects the maps storage device, microSD card or embedded multimedia card (eMMC), has encountered a filesystem error, which may affect navigation functionality.
|
The maps storage device (microSD card or eMMC) encounters a filesystem error.
|
Navigation may be unavailable or may not function as expected.

|
-
|
|
|
The Graphics Processing Unit (GPU) has encountered a major issue, causing it to stop working (aka wedged) and potentially making the system slow or unresponsive.
|
The GPU engines are declared wedged by the Media Control Unit (MCU).
|
System performance may be severely degraded or unresponsive.
|
|
|
The recovery process for the Graphics Processing Unit (GPU) has failed, indicating a persistent problem. System may be slow or unresponsive.
|
The GPU recovery process fails to recover the GPU.
|
System performance may be severely degraded or unresponsive.
|
|
|
USB drive has no medium

|
|
|
The GUI_neverSleep data value in the UI prevents the vehicle from going to sleep and may lead to an increased rate of battery drain.
|
|
-
|
|
|
The Media Control Unit (MCU) detects the user interface (UI) frames per second (FPS) rate is below the minimum threshold.
|
The UI draw rate is less than 15FPS, indicating the FPS counter is crawling.
|
The UI may be slow to respond and/or appear to be lagging.

|
|
|
The audio watchdog detects a critical audio error during vehicle wake, which may cause the Media Control Unit (MCU) to restart and/or audio to be temporarily unavailable.
|
The audio watchdog detects a critical audio error within 60 seconds of vehicle wake.
|
If blocked alert log signal values are reported, audio may be unavailable until the next vehicle wake. If rebooted alert log signal values are reported, the MCU will reboot.
|
|
|
