Alerts

The DI ECU detects an uncorrectable flash or RAM error.

This alert is for diagnostic logging purposes only.

HVIL is no longer CLOSED

Contactors may not close

The DIx power stage is not ready. One of the pre-drive gate driver checks has failed. There may be a condition affecting the DIx control board.

DIx may not function as expected.

The DI ECU resets for an unintended reason. Alert log signal data should provide more information on the specific reason.

The DI ECU is unavailable while it resets.

Stator anomaly observed during retry attempt

Drive unit may fault

The DIx current sensor hardware comparator has detected a peak on Phase C.

DIx may be inoperable.

The DIx current sensor hardware comparator has detected a peak on Phase B.

DIx may be inoperable.

DIx has detected a condition affecting functionality at the gate driver on Phase C. View payload signal to confirm reason for alert.

DIx may be inoperable.

DIx has detected a condition affecting functionality at the gate driver on Phase B. View payload signal to confirm reason for alert.

DIx may be inoperable.

DIx has detected a condition affecting functionality at the gate driver on Phase A. View payload signal to confirm reason for alert.

DIx may be inoperable.

Adverse oil pressure detected or DC current sensor rationality degraded, see reason payload

Drive Unit thermal estimation and limits are conservative, potential torque limiting with aggressive driving, recommend inspecting drive unit oil level and oil pump

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.

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 the PCS.

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

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.

Inverter detects a shorted switch

Inverter may not allow drive on next drive cycle

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.

Not Available

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.
