Alerts

The DIx ECU detects no phase current. The phase lugs, stator, rotor, or DIx may have a condition affecting functionality.

Without phase current, DIx cannot produce motor torque to rotate the wheels. The vehicle's drive cycle may not function as expected, or at all.

No

The DIx EEPROM has reported phase sensor calibration is outside valid range.

This alert is primarily for logging purposes and appears in conjunction with other alerts.

No

The DI ECU is not receiving the expected CAN communication from the EPB, and considers it irrational or MIA.

The DI ECU is unable to monitor the state of the EPB.

No

The Drive Unit is not able to transition to Drive state. There may be a condition preventing the Drive Unit from transitioning states.

The Drive Unit may not function as expected, including a reduction in vehicle power. The vehicle's drive cycle may not function as expected, or at all.

No

DIx has detected an error communicating with FPGA. There may be a condition affecting the DIx control board functionality.

The DIx Gate Drive Unit may not be able to receive data from the Pedal Monitor. The vehicle's drive cycle may not function as expected.

No

Any received HVLINK frame is MIA

Active discharge may turn ON

No

The DI ECU does not receive the expected CAN messages from the PCS.

The DI ECU is unable to monitor the state of the PCS.

No

The drive interface (DI) or drive inverter (DIx) electronic control unit (ECU) detects a condition that prevents the drive unit(s) from generating excess heat. Alert log signal data provides information on the specific condition(s) detected.

The drive unit(s) cannot produce excess heat when requested.

No

The DI ECU is not receiving the expected CAN communication from the EPAS3, and considers it irrational or MIA.

The DI ECU is unable to monitor the state of the EPAS3.

No

The HV bus has measured a voltage anomaly in the HV battery pack. DIx may not operate as expected.

DIx may not operate as expected. Drive torque may be restricted.

No

Drive unit rotor offset, rotor flux, or resolver error learning routine is in progress.

Drive unit torque is limited and pending spindown sequence.

No

The DI ECU is not receiving the expected CAN communication from the IBST, and considers it irrational or MIA.

The DI ECU is unable to monitor the state of the IBST.

No

The DI ECU is not receiving the expected CAN communication from the RCM, and considers it irrational or MIA.

The DI ECU is unable to monitor the state of the RCM.

No

The DI ECU is not receiving the expected CAN communication from the VCSUPER, and considers it irrational or MIA.

The DI ECU is unable to monitor the state of the VCSUPER.

No

The DI ECU is not receiving the expected CAN communication from the VCFRONT, and considers it irrational or MIA.

The DI ECU is unable to monitor the state of the VCFRONT.

No

The Drive Unit resolver is not operating as expected. The resolver may have a condition affecting functionality.

The resolver is not operating as expected. The DIx invertor control board may be unable to correctly detect the angle and speed of the rotor.

No

Loss of communication or power to oil pump, or persistent oil pump motor stall or fault occurred

Initiates reduced drive unit performance and a speed limit on the vehicle, due to reduced gear lubrication and motor cooling

No

Loss of communication or power to oil pump, persistent oil pump motor stall occurred, or persistent condition affecting oil pump functionality detected

Initiates reduced drive unit performance and a speed limit on the vehicle, due to reduced gear lubrication and motor cooling

No

The DI detects the at-speed recovery mechanism encounters an error affecting its functionality. Alert log signal data provides information on the specific condition(s) detected.

The vehicle may lose propulsion.

No

DIx has detected unexpected oil pressure from the oil pump. The oil pump may have a condition affecting functionality.

Drive Unit thermal estimation and limits may be impacted and not function as expected. Torque production could be limited.

No
