Signal Name Description Condition Impact Important
The drive interface (DI) electronic control unit (ECU) detects that the front drive interface (DIF) controller area network (CAN) node is missing (MIA).
The DI ECU is not receiving the required feedback CAN messages from the DIF.
The DI ECU is unable to monitor the state of the DIF.
No
Drive Inverter Warning: Stator over temperature
Stator temperature exceeds upper temperature threshold
No direct impact. Could damage drive unit if temperature is continuously too high.
No
The Drive Inverter (DIx) Phase B current sensor is irrational.
The DIx Phase B current sensor is irrational. An irrational current may indicate a high rate of change or current measurement out of sensing bounds. There may be a condition affecting current input and output.
If the alert asserts at the beginning of a drive cycle, DIx may not enable. If the alert asserts during a drive cycle, DIx may be disabled. DIx may not function as expected.
No
The Drive Inverter (DIx) Phase A current sensor is irrational.
The DIx Phase A current sensor is irrational. An irrational current may indicate a high rate of change or current measurement out of sensing bounds. There may be a condition affecting current input and output.
If the alert asserts at the beginning of a drive cycle, DIx may not enable. If the alert asserts during a drive cycle, DIx may be disabled. DIx may not function as expected.
