Alerts

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.

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

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.

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.

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.

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.

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 C. View payload signal to confirm reason for alert.

DIx may be inoperable.

Abnormal temperature measurements from heatsink sensor

Unable to monitor heatsink sensor temperature

Heatsink temperature (refer to heatsinkTemp) drops below lower temperature threshold

No direct impact. Could damage drive inverter if temperature is continuously too low.

Heatsink temperature (refer to heatsinkTemp) exceeds upper temperature threshold

No direct impact. Could damage drive inverter if temperature is continuously too high.

Abnormal temperature measurements from ambient sensor

Unable to monitor ambient sensor temperature

Ambient temperature (refer to pcbTemp) drops below lower temperature threshold

No direct impact. Could damage drive inverter if temperature is continuously too low.

Ambient temperature (refer to pcbTemp) exceeds upper temperature threshold

No direct impact. Could damage drive inverter if temperature is continuously too high.

Any received HVLINK frame is MIA

Active discharge may turn ON

The DIx and PM estimate different amounts of torque production, causing a Cross Check mismatch. There may be a condition affecting DIx's or PM's ability to measure torque.

The vehicle may not accurately measure the level of torque being produced by the Drive Unit.

Drive Inverter temperature (refer payload signals for temperatures) exceeds upper temperature threshold

No direct impact. Could damage drive inverter if temperature is continuously too high.

The DI core detects an abort data exception. Alert log signal data provides information on the specific condition(s) detected.

This alert is primarily informational and is used for logging purposes.

The three DIx heat sink sensors are not functioning. The DIx heat sink sensors may have a condition affecting functionality.

Since it cannot detect temperature as expected, DIx may limit power output to an operational level. Drive Unit performance may be impacted.

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.
