| Signal Name | Description | Condition | Impact | Important |
|---|---|---|---|---|
|
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.
|
No
|
|
|
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.
|
No
|
|
|
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.
|
No
|
|
|
The Power Line Communication Relay (PLCRLY) electronic control unit (ECU) receives pilot sensor readings that are outside of the expected range.
|
The PLCRLY ECU senses pilot voltage, period, or a duty cycle outside of the expected range that cannot be categorized into a valid pilot state.
|
Charging does not start.
|
No
|
|
|
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.
|
No
|
|
|
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.
|
No
|
|
|
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.
|
No
|
|
|
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.
|
No
|
|
|
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.
|
No
|
|
|
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.
|
No
|
|
|
Invalid MAC address written to CP genealogy
|
MAC address stored in genealogy is invalid
|
CCS DC charging may not start
|
No
|
|
|
Calibration in use does not match firmware expectation
|
Saved calibration does not match firmware expectation
|
System may block steering if position can not be determined
|
No
|
|
|
Indicates that communication between the EVSE and the CP timed out
|
Timer between establishing communications with EVSE and starting charge expires
|
Charging will not start
|
No
|
|
|
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.
|
No
|
|
|
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.
|
No
|
|
|
The GTW configuration for PLC support does not match the hardware installed in the vehicle
|
Configuration of the GTW PLC support type does not match the Charge Port configuration
|
The GTW will not update the PLC modem and PIB during OTA updates
|
No
|
|
|
The rack moved unexpectedly during preload for calibration or position detection
|
Rack sensors report rack movement of more than 0.5mm during a single preload cycle.
|
Calibration or position detection cannot complete successfully.
|
No
|
|
|
PCS bootloader configured the clock source to use the internal clock (INTOSC2), because the DSP has reported a missing clock from the external crystal oscillator
|
On boot, PCS is not using the external crystal oscillator (XTALOSC)
|
Internal oscillator is less precise, potentially has system behavior impact
|
No
|
|
|
PCS has detected at least one reset during the boot up process. AC charging power might be limited if phase damaged is detected
|
Power conversion system detected reset while enabling a phase
|
Reduced AC charge rate or inability to AC charge if pahse damaged is detected
|
No
|
|
|
PCS detects one or more power converter expected AC voltage sources are missing, possibly due to bad utility wiring or vehicle HV harness connection
|
Charger detects that one or more expected AC voltage sources is missing, possibly due to bad external wiring
|
Reduced AC charge rate or inability to AC charge
|
No
