Signal Name Description Condition Impact
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.
The motor is operating at high phase currents for more than 10 seconds.
Compressor may overheat and shutdown.
At least one of the temperature sensors has reached the overtemp warning threshold.
At least one temperature sensor is above the respective warning temperature threshold.
Compressor may shut down if temperature sensors continue to rise in temperature.
High Voltage (HV) compressor does not start multiple times and does not reach the target speed.
Compressor is unable to start 5 times during a power cycle.
Loss of HVAC heating and cooling. Compressor does not operate for the remainder of the power cycle.
The HV Compressor failed to start and reach the target speed.
While trying to start, the HV Compressor was not able to spin and reach its target speed.
The HV Compressor will not produce the required pressure for the duration of this alert.
At least one of the temperature sensors is detecting an overtemperature. Compressor will be shutting down.
At least one temperature sensor is sensing a temperature above the maximum temperature threshold.
Compressor will not operate.
The HV bus voltage is too low for the compressor to start.
HV bus voltage is below minimum operating voltage.
Compressor will stay in standby.
VCRIGHT node is Missing-in-Action (MIA) on THERMAL CAN bus.
Any consumed VCRIGHT frame is missing.
Inverter may not execute VCRIGHT commands.
The compressor high voltage powerstage gate drivers reported an electrical condition preventing their operation.
Any gate driver is reporting an electrical condition affecting its functionality.
The compressor will not operate.
The internal 1V2 supply has an overvoltage condition.
1V2 supply rises above upper voltage limit
The processor may stop operating if this condition continues or worsens.
The internal 1V2 supply has an undervoltage condition.
The 1V2 supply drops below the lower voltage limit.
The processor may reboot or stop operating if the condition worsens.
The internal 3V3 supply voltage has an overvoltage condition.
The 3V3 supply rises above the upper voltage limit.
The compressor hardware may get damaged. Sensors may report incorrect values.
The internal 3V3 supply voltage is too low.
The 3V3 supply voltage drops below the lower voltage limit.
The compressor processor may shut down. Sensors may provide incorrect readings.
The 12V supply of the compressor is above the maximum expected value.
The 12V supply rises above the upper voltage limit of 20.5V.
The compressor hardware may be damaged as a result of an overvoltage condition.
The 12V supply of the compressor is below the minimum expected value.
12V supply drops below lower voltage limit of 9V.
This alert is for diagnostic purposes only. The compressor may reset or stop operating as a result of this undervoltage.
