Alerts

Inverter detects a shorted switch

Inverter may not allow drive on next drive cycle

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.

Motor regulation fails to meet command inputs

Drive unit enters unit limp mode (see DI_a126_limpMode)

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).

Any received HVLINK frame is MIA

Active discharge may turn ON

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.

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

The motor is permanently disabled.

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

Drive unit torque is limited and pending spindown sequence.

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

TAS may be unavailable.

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.

DIx has missed 3 to 5 messages from the main controller. DIx will maintain the last commanded torque value, then 0 Nm.

This alert is primarily informational and is used for logging purposes. No expected impact on vehicle functionality.

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.
