|
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: 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: 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.
|
|
|
The Pedal Monitor (PM) processor has detected an internal exception. This alert does not on its own indicate a symptom or root cause.
|
The PM processor detects an exception.
|
This alert is primarily informational and is used for logging purposes.
|
|
|
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.
|
|
|
The Pedal Monitor (PM) processor has detected an internal exception. This alert does not on its own indicate a symptom or root cause.
|
The PM processor detects an exception.
|
This alert is primarily informational and is used for logging purposes.
|
|
|
The Pedal Monitor (PM) processor has detected an internal exception. This alert does not on its own indicate a symptom or root cause.
|
The PM processor detects an exception.
|
This alert is primarily informational and is used for logging purposes.
|
|
|
The Pedal Monitor (PM) processor has detected an internal exception. This alert does not on its own indicate a symptom or root cause.
|
The PM processor detects an exception.
|
This alert is primarily informational and is used for logging purposes.
|
|
|
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.
|
|
|
Pedal Monitor Warning: DI and PM versions do not match.
|
This condition is set when the inter-process communication version between DI and PM is mismatched.
|
Prevents DI ECU from booting, presents itself as a complete inhibition of drive unit capability.
|
|
|
The Pedal Monitor (PM) detects that the measured high voltage interlock loop (HVIL) current is consistently an irrational value, which may affect PM functionality.
|
The PM detects the measured HVIL current is consistently an irrational value for more than 60 seconds.
|
Vehicle functions that depend on PM HVIL statuses may be unavailable, or their performance may be affected. Other alerts may also be present as the high voltage (HV) battery contactors will be unable to close.
|
|
|
Pedal Monitor Warning: CAN hardware error.
|
This condiiton is set when CAN peripheral hardware indicates an overrun or transmission error on the secondary CAN bus.
|
No immediate impact, may lead to indicating an MIA condition for the specific CAN ID listed in alert payload.
|
|
|
Pedal Monitor Warning: Resolver operation abnormal.
|
The safety monitor sets this condition when resolver speed or angle measurements in correspondence with DI are considered irrational or out of bounds.
|
The safety monitor will inhibit torque and excess heat production for the remainder of the drive cycle.
|
|
|
Pedal Monitor Warning: UI CAN node is missing.
|
The safety monitor sets this condition when CAN communication from UI is considered irrational or missing.
|
UI is considered not communicating on CAN for remainder of drive cycle.
|
|
|
Pedal Monitor Warning: VCFRONT CAN node is missing.
|
The safety monitor sets this condition when CAN communication from VCFRONT is considered irrational or missing.
|
VCFRONT is considered not communicating on CAN for remainder of drive cycle.
|
|
|
Pedal Monitor Warning: Motor movement detected during stationary excess heat.
|
The safety monitor sets this condition when rotor movement is detected during stationary excess heat production.
|
The safety monitor will inhibit torque and excess heat production for the remainder of the drive cycle.
