This message contains separate signals for Overvoltage and Undervoltage for each rail.
|
ECU 5V rail detected < 4.5V or > 5.5V, or 3.3V rail < 3.0V or > 3.6V for 100ms.
|
These are the repercussions of the alert being set
|
|
|
The electronic control unit (ECU) detects that the supply voltages from 1 or more components are out of range.
|
The ECU detects the supply voltage is < 7.31V. Specific reason(s) should be available in alert log signal data.
|
The ECU may be unavailable.

The SBC CAN transceiver has faulted. Alert will be seen if the trasnceiver has recovered from the faulted condition.
|
The BDY CAN bus communication is not available.
|
Other ECUs may report this ECU as being MIA and behaviour will be impacted. This alert won't be seen until CAN communcation has returned.

|
|
|
A condition affecting switch functionality has been detected.
|
A condition is detected affecting switch functionality. Alert log signal data should provide more information on the switch affected and specific condition.
|
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.
|
|
|
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.
|
|
|
The vehicle controller detects the supply voltage from 1 or more components is outside of the expected range.
|
The vehicle controller detects the supply voltage from 1 or more components is < 7.31. Alert log signal data should provide more information on the specific condition(s) detected.
|
Features depending on the vehicle controller functionality may be unavailable or may not function as expected.
|
|
|
Warns if the processor has experienced a reset due to power loss.
|
Sudden power loss.
|
Controller is MIA for some time.
|
|
|

|
The most common cause of this fault is the MISO line being held low on HSD U19.
|
The Freescale HSD has been returned bad data on the MISO line from the microprocessor more than 10 times in a row.
|
HSD outputs could toggle endlessly causing lights to strobe forever.
