Alerts

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

LV supply voltage to DI is disconnected or drops below lower voltage threshold.

The DI ECU triggers limp mode (see separate limpMode alerts) and cannot produce torque or power.

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.

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.

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

The Drive Unit may not operate as expected.

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 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 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.

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

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 DIx ECU has detected an error with ADD.

Gear train and drive line thuds and noise typically dampened by ADD may be more noticeable.

The DI ECU detects an uncorrectable flash or RAM error.
