Alerts

The DIx ECU has detected an error communicating with LIN. The DIx LIN node(s) or LIN signal-carrying wire may have a condition affecting functionality.

DIx and the oil pump communicate through LIN. DIx may not communicate with the oil pump as expected.

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

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

DIx has detected a quantity of torque production that indicates Drive Unit wear.

The Drive Unit may have wear resulting from torque production. The vehicle may enter launch mode torque.

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

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

Set if any of the checked gateway config is not as expected.

The vehicle enters system limp mode and is unable to enter Drive.

The DI ECU is not receiving the expected CAN communication from the EGGRIGHT3, and considers it irrational or MIA.

The DI ECU is unable to monitor the state of the EGGRIGHT3.

DIx has detected an error communicating with SPI, which monitors the pedal monitor. There may be a condition affecting SPI.

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

The DI ECU receives irrational or no data from the WSS.

This alert is primarily informational. If it persists, traction control may become unavailable.

DIx has detected the capacitor is over temperature. The pack contactors may have a condition affecting functionality.

The flow of current between the capacitors and DIx may not function as expected.

Drive Unit GPO has been triggered. The Drive Unit will lose current input from the HV battery.

The Drive Unit will ramp down all torque production. The Drive Unit may not function as expected.

Number of qualified high speed events above allowed threshold

Silent alert to track mechanical wear

Software detects a shorted semiconductor switch. The alert log signals provide detailed trigger algorithm info.

The motor is permanently disabled.

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

The DI ECU is unable to monitor the state of the HVP, and active discharge may turn on.

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.

Motor regulation fails to meet command inputs

Drive unit enters unit limp mode (see DI_a126_limpMode)

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.

The DIx node is MIA on CAN for one or more messages. The DIx node or DIx may have a condition affecting functionality.

DIx may not be able to communicate with the High Voltage Processor (HVP).

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.

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.

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.
