Alerts

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

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

No

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.

No

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

The motor is permanently disabled.

No

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.

No

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.

No

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.

No

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.

No

The DIx power stage has applied a safe state.

Some DIx features may be disabled, or may not function expected. The Drive Unit may not function as expected.

No

The PM detects a condition that requires it to intervene and disable powertrain.

Vehicle drive torque is immediately disabled.

No

Abnormal condition detected within drive unit subsystem. Look at limpReason in alert for exact trigger.

Drive system performance severely reduced (torque/power limited)

No

Motors are not responding to DI commands

Unable to produce torque/power from drive unit

No

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.

No

Motor regulation fails to meet command inputs

Drive unit enters unit limp mode (see DI_a126_limpMode)

No

Any received HVLINK frame is MIA

Active discharge may turn ON

No

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.

No

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).

No

Number of qualified high speed events above allowed threshold

Silent alert to track mechanical wear

No

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.

No

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.

No

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.

No
