|---|---|---|---|
|
Pedal Monitor Warning: Switch-off Path Test Failed.
|
This condition is set when the power electronics and DI-PM switch-off path test fails, most likely due to damaged inverter hardware.
|
The safety monitor will inhibit torque and excess heat production for the remainder of the drive cycle.
|
|
|
Pedal Monitor Warning: Peripheral Register Configuration Error.
|
This condition is set when a the GPIO register of the ECU reports a configuration error, intended to be a diagnostic alert only.
|
No immediate impact.
|
|
|
Pedal Monitor Warning: DI Heartbeat is missing.
|
The safety monitor sets this condition when DI Heartbeat communication is too fast or too slow.
|
The safety monitor will initiate a unit limp condition for the remainder of the drive cycle.
|
|
|
Pedal Monitor Warning: Reset for unintended reason.
|
This condition is set when this ECU powers on and detects an abnormal reset condition from the previous power cycle (for example, from a watchdog timeout).
|
No immediate impact.
|
|
|
Pedal Monitor Warning: Stator Temperature Sensor Error.
|
The safety monitor sets this condition when stator temperature sensor measurements are irrational or out of bounds.
|
No immediate impact.
|
|
|
Pedal Monitor Warning: Motor Encoder error.
|
The safety monitor sets this condition when encoder speed sensor measurements are irrational or out of bounds.
|
The safety monitor will initiate a unit limp condition for the remainder of the drive cycle.
|
|
|
Pedal Monitor Warning: Parking Brake CAN node is missing.
|
The safety monitor sets this condition when CAN communication from Parking Brake CAN node is considered irrational or missing.
|
Parking Brake CAN node is considered not communicating on CAN for remainder of drive cycle.
|
|
|
Pedal Monitor Warning: CAN hardware error.
|
This condiiton is set when CAN peripheral hardware indicates an overrun or transmission error on the primary CAN bus.
|
No immediate impact, may lead to indicating an MIA condition for the specific CAN ID listed in alert payload.
|
|
|
Pedal Monitor Warning: Phase Current Irrational.
|
The safety monitor sets this condition when phase current sensor measurements are irrational or out of bounds.
|
The safety monitor will initiate a unit limp condition for the remainder of the drive cycle.
|
|
|
Pedal Monitor Warning: DI CAN node is missing.
|
The safety monitor sets this condition when CAN communication from DI is considered irrational or missing.
|
DI is considered not communicating on CAN for remainder of drive cycle.
|
|
|
Pedal Monitor Warning: DI torque actual does not match PM torque measured.
|
Set when absolute difference between DIx_torqueActual and PMx_torqueMeasured is > 100Nm for 100ms
|
No immediate impact.
|
|
|
Pedal Monitor Warning: Torque Detected in non-torque producing gear.
|
The safety monitor sets this condition torque production error is detected.
|
The safety monitor will inhibit torque and excess heat production for the remainder of the drive cycle.
|
|
|
Pedal Monitor Warning: Deceleration Torque.
|
The safety monitor sets this condition torque production error is detected.
|
The safety monitor will inhibit torque and excess heat production for the remainder of the drive cycle.
|
|
|
Pedal Monitor Warning: Torque Reversal.
|
The safety monitor sets this condition torque production error is detected.
|
The safety monitor will inhibit torque and excess heat production for the remainder of the drive cycle.
|
|
|
Pedal Monitor Warning: Accumulated Torque.
|
The safety monitor sets this condition torque production error is detected.
|
The safety monitor will inhibit torque and excess heat production for the remainder of the drive cycle.
|
|
|
Pedal Monitor Warning: Absolute Torque.
|
The safety monitor sets this condition torque production error is detected.
|
The safety monitor will inhibit torque and excess heat production for the remainder of the drive cycle.
|
|
|
Pedal Monitor Warning: Smart watchdog fault.
|
The safety monitor sets this condition when smart watchdog faults are present.
|
Loss of torque production. The safety monitor and drive inverter may reset.
|
|
|
Pedal Monitor Warning: Crystal oscillator inactive.
|
This condition is at application boot when the external crystal is not the active clock source.
|
Unit may have limited torque or torque disablement with this alert present, see other active alerts for more details.
|
|
|
Pedal Monitor Warning: Torque Intervention.
|
The safety monitor sets this condition and indicates diagnostic information in its payload for root cause analysis.
|
The safety monitor will inhibit torque and excess heat production for the remainder of the drive cycle.
|
|
|
Pedal Monitor Warning: ECC Protection anamoly detected.
|
This condition is set when ECC protection detected a flash fetch or RAM read error, intended to be a diagonstic alert only.
|
No immediate impact.
