Alerts

One or more of the expected messages from the PEPS ECU is not received.

Power steering may be limited or unavailable.

One or more of the expected messages from the SEPS ECU is not received.

Power steering may be limited or unavailable.

PCS detects there are misconfigurations.

DCDC and/or AC charging may not function properly

Charger does not receive all expected DCDC interface CAN messages from vehicle controller

DCDC converter does not regulate LV bus voltage to target, LV battery may not charge correctly

Ambient temperature is outside of expected range for more than 1s

DCDC insufficient cooling check will be disabled if the ambient temp sensor is irrational

One or more of the expected messages from the SSFA ECU is not received.

Steering wheel feedback functionality may be limited or unavailable.

One or more of the expected messages from the PSFA ECU is not received.

Steering wheel feedback functionality may be limited or unavailable.

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.

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.

A message the local ECU expects to receive from the APP ECU is not received within the expected timeout, or the drop rate is too high while the APP is CAN active.

Autopilot does not operate as expected.

Non-volatile memory misconfiguration or underlying flash/filesystem error.

Non-volatile memory records may be incorrect or missing.

In the three-phase delta grid, onboard charger's L3 conductor is energized while L2 is not energized.

Reduced AC charging rate.

During initialization, the PCS ECU detects the High Voltage Processor (HVP) is already sending a control request for low voltage (LV) support, indicating the PCS likely experienced a reset or power cycle unexpectedly while performing DCDC operations.

No expected impact on vehicle functionality.

The PCS ECU detects a viper chip condition preventing the charger phase from boosting the intermediate bus to the specified threshold.

No expected impact on vehicle functionality.

When 5V logic power rail is irrational and DCDC experienced faults when using it is original control scheme

DCDC running under sensorless control mode and some DCDC hardware protection may be affected

When 5V logic power rail exceeds 5.8V continuously for more than 1 minute

Car unable to start or drive, LV battery and system cannot be supported, AC charging functionality may also be affected

Power conversion system detects that a logical power rail voltage is outside expected range for more than one second

Inability to precharge HV bus, inability to support 12V system, inability to AC charge, inability to drive

The PCS ECU detects the micro grid frequency significantly droops below the specified threshold.

AC charging will be unavailable to help reduce the load on the micro grid.

The PCS ECU detects charging power is limited for more than 10 minutes due to excessive intermediate bus voltage ripples. Alert log signal data should provide more information on the specific condition(s) detected.

The rate of AC charging may be limited by the PCS.

The PCS ECU detects the intermediate bus voltage ripple peak-to-peak value for the charger phase exceeds the specified threshold.

The rate of AC charging may be reduced, or AC charging may be unavailable.
