|
The switch may not function or may not function 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 expected controller area network (CAN) messages from the Autopilot Primary (APP) were not received.

|
A watchdog (external or internal) was not serviced in time.
|
Controller is MIA for some time.
|
|
|
The local Electronic Control Unit (ECU) has not received one or more expected Controller Area Network (CAN) messages from the internal steering bus.
|
The local Electronic Control Unit (ECU) did not receive a message it was expecting from the ECUs on the specified internal steering bus within the expected timeout.
