|
One or more of the tire cavity temperature sensors report a very high temperature to the Tire Pressure Monitoring System vehicle controller (VCTPMS).
|
One or more of the tire cavity temperature sensors report a temperature above 90 degrees C (or 194 degrees F).
|
Excessive tire wear may occur, and the surrounding components may be damaged.
|
|
|
The front left tire cavity temperature sensor reports a very high temperature to the Tire Pressure Monitoring System vehicle controller (VCTPMS).
|

|
|
|
One or more of the expected controller area network (CAN) messages from the Autopilot Primary (APP) were not received.
|
A message the local ECU expects to receive from the APP ECU is not received within the expected timeout, or the drop rate is too high while the APP is CAN active.
|
Autopilot does not operate as expected.
|
|
|
A large voltage drop is detected in the input power to the vehicle controller, indicating the resistance on the input power feed to the vehicle controller is higher than expected.
|
Estimated resistance on the input power feed to the vehicle controller is higher than expected.
|
The vehicle controller may be unavailable due to lack of adequate input power, limiting vehicle functionality or making the vehicle inoperable, with at least one other alert specific to that condition present.
|
|
|
One or more of the messages the vehicle controller receives periodically from the rear left drive inverter (DIREL) is not received, indicating the DIREL may be unavailable (MIA).
|
One or more of the expected messages from the DIREL is not received.
|
Vehicle speed and power may be limited.
|
|
|
One or more of the messages the vehicle controller receives periodically from the rear right drive inverter (DIRER) is not received, indicating the DIRER may be unavailable (MIA).
|
One or more of the expected messages from the DIRER is not received.
|
Vehicle speed and power may be limited.
|
|
|
More than half of the Electronic Control Units (ECUs) on either the Left CAN (LC) or Right CAN (RC) bus are missing more than half their messages while the bus should be active.
|
If 50% or more of the ECUs the local ECUs listens to are MIA, and the local ECU receives from more than 3 ECUs on this bus. An ECU is MIA if more than 50% of its messages are MIA and that ECU is considered CAN active (see specific ECU's MIA alert for CAN active conditions).
|
Vehicle functionality may not operate as expected.
|
|
|
An issue is indicated from the non-volatile memory manager.
|
Non-volatile memory misconfiguration or underlying flash/filesystem error.
|
Non-volatile memory records may be incorrect or missing.
