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

Rotor offset mean estimator is above minimum rationality threshold at very low absolute torque outputs

Diagnostic alert data only, may indicate reduction in torque or excess heat accuracy

The DIx ECU has detected the current sensor offset has exceeded the threshold on Phase B. Phase B hardware may need investigation.

This alert is intended for logging purposes. Phase B hardware may need investigation.

The DIx ECU has detected the current sensor offset has exceeded the threshold on Phase A. Phase A hardware may need investigation.

This alert is intended for logging purposes. Phase A hardware may need investigation.

The DIx ECU has detected the current sensor RMS current has exceeded the expected RMS threshold on Phase C.

DIx may not function as expected, including vehicle power being limited.

The DIx ECU has detected the current sensor RMS current has exceeded the expected RMS threshold on Phase B.

DIx may not function as expected, including vehicle power being limited.

The DIx ECU has detected the current sensor RMS current has exceeded the expected RMS threshold on Phase A.

DIx may not function as expected, including vehicle power being limited.

The DIx ECU has detected a peak in Phase C.

DIx may be inoperable.

The DIx ECU has detected a peak in Phase B.

DIx may be inoperable.

The DIx ECU has detected a peak in Phase A.

DIx may be inoperable.

The Switch Off Path Test (SOPT) for Drive Unit has failed. The DIx and PM torque measurements are different. The pathway between DIx and PM may have a condition affecting functionality.

PM may not be able to shut down torque produced by Drive Unit.

The FPGA detects a 5V supply regulator PGOOD is not working as expected.

Readings from 5V sensors may become erratic.

HV bus voltage exceeds set upper voltage threshold

Unable to produce torque/power from drive unit

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

Vehicle drive torque is immediately disabled.

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.
