|
|
|
The charge port (CP) electronic control unit (ECU) detects an overcurrent condition with the CP status LEDs.
|
The current to the CP status LEDs is higher than expected.
|
The CP status LEDs may not turn on or may flicker.
|
|
|
The charge port (CP) electronic control unit (ECU) detects an undercurrent condition with the CP status LEDs.
|
The current to the CP status LEDs is lower than expected.
|
The CP status LEDs may not turn on or may flicker.
|
|
|
The charge port (CP) electronic control unit (ECU) detects an error during a charge session with a Guobiao direct current (GB DC) charging station, causing the charge session to be aborted.
|
The CP ECU detects an error during a GB DC charging session.
|
GB DC charging may not start or may be interrupted.
|
|
|
The charge port (CP) electronic control unit (ECU) detects an under voltage condition on the internal 5V power supply.
|
The internal 5V power supply voltage measured by the CP ECU is below 4.5V.
|
The charge port may not function as expected.
|
|
|
The charge port (CP) electronic control unit (ECU) detects an over voltage condition on the internal 5V power supply.
|
The internal 5V power supply voltage measured by the CP ECU is above 5.5V.
|
The charge port may not function as expected.
|
|
|
The charge port (CP) electronic control unit (ECU) detects lower than expected voltage from the low voltage (LV) battery.
|
The CP ECU detects LV supply less than 8V.

|
|
|
A phase current offset of the compressor multiphase motor is greater than the expected variance. Compressor may not operate as expected.
|
A phase current offset greater than the expected variance is detected.
|
Compressor may not operate as expected. Controller may be damaged.
|
|
|
More than half of the ECUs on a either the VEH or PARTY bus are missing more than half their messages while the bus should be active.
|
If 50% or more of the ECUs the local ECUs listens to are MIA, and the local ECU receives from more than 3 ECUs on this bus. An ECU is MIA if more than 50% of its messages are MIA and that ECU is considered CAN active (see specific ECU's MIA alert for CAN active conditions).
|
Vehicle functionality may be degraded.
|
|
|
One or more of the gate drivers expired its available retries.
|
The internal gate driver set the FLT bit regardless of retry attempts.
|
The HV compressor will not be able to spin and provide heating/cooling
|
|
|
The compressor high voltage powerstage gate drivers reported improper input voltage preventing their operation.
|
Any gate driver is reporting an electrical condition affecting its functionality.
|
The compressor will not operate.
|
|
|
High Voltage Interlock Loop (HVIL) circuitry self-test detected an internal short.
|
The vehicle does not detect a disconnect along the HVIL during a self-test.
|
The HVIL cannot identify when there is a disconnect.
|
|
|
One or more of the messages the vehicle controller receives periodically from the supermanifold vehicle controller (VCSUPER) is not received, indicating the VCSUPER may be unavailable (MIA).
|
The vehicle controller does not receive one or more of the expected messages from the VCSUPER within the expected time frame.
|
Vehicle functions that depend on the VCSUPER may be unavailable or may not function as expected.
|
|
|
BMS node is Missing-in-Action (MIA) on THERMAL CAN bus.
|
Any consumed BMS frame is missing.
|
Inverter may not execute BMS commands.
|
|
|
One of the gate driver power supplies expired its available retries.
|
The internal gate drive power supply had to shut down too many consecutive times. The compressor is aborting retries to prevent possible additional hardware damage.
|
The HV compressor will stop operating as power to the corresponding gate driver becomes insufficient.
|
|
|
The HV Compressor had a loss of motor control causing the compressor to stop spinning.
|
Motor control lost control due to the speed dropping below a minimum threshold or from system disturbances.
|
Compressor will stop momentarily.
|
|
|
At least one of the gate driver power supplies had to shut down due to an electrical condition.
|
At least one gate drive power supply is reporting power not good via its PGOOD pin.
|
Compressor will not operate if power to any gate driver is insufficient.
|
|
|
The motor is operating at high phase currents and risks overheating.
|
