|
Supercharger detected a low isolation measurement while connected to the vehicle.
|
Supercharger isolation measurement result was less than the fault threshold.
|
May cause breakdown of isolation on the Supercharger or vehicle High Voltage (HV) link.
|
No
|
|
|
The Supercharger Electronic Control Unit (ECU) detects proximity voltage in an unexpected range.
|
The Supercharger ECU detects that proximity voltage is outside of the expected range.
|
Charging will stop.
|
No
|
|
|
A Lower limit breach was identified in Supercharger isolation voltage input status.
|
Supercharger detected under threshold voltage values meant for exterior circuit isolation checks.
|
Supercharger hardware may be exposed to reduced efficiency and increased susceptibility to electromagnetic interference.
|
No
|
|
|
Supercharger did not receive all of the expected messages from the Battery Management System (BMS).
|
Supercharger did not receive all of the expected messages from the BMS.
|
An emergency shutdown can occur while charging, or charging may never start.
|
No
|
|
|
Stage allocation timed-out during the voltage matching part of the sequence.
|
Voltage matching took too long to complete and stage allocation timed out.
|
Stage will not connect to desired post, resulting in reduced power availability.
|
No
|
|
|
Supercharger detected a voltage arc, either legitimately, or as a result of the High Voltage (HV) circuit being opened under load.
|
Supercharger detects a rapid change in energy on the HV bus, matching the signature for an arc.
|
May result in thermal damage to components, or welding/fatigue on Fast Charge (FC) contactors.

|
Secondary disconnect controller (SDC) failed the drive unit pyro self-test.
|
Pyro test voltages were out of range during pyro self-test.
|
Pyro disconnect may not function as expected.
|
No
|
|
|
Drive inverter (DI) running-feedback (fdbk) pin to secondary disconnect controller (SDC) is in an irrational state.
|
DI UART data is active, but running-feedback pin state is low.
|
SDC will not skip pyro self-test (PST) if DI is MIA at startup. Potential overlapping pyro self-tests.
|
No
|
|
|
Secondary disconnect controller (SDC) triggered the 2-phase disconnect mechanism.
|
SDC detects abnormal electrical condition.
|
Drive unit may be permanently disabled after 2-phase disconnect occurs.
|
No
|
|
|
Secondary disconnect controller (SDC) detected abnormal motor currents.
|
Detection of abnormal drive unit currents by the SDC when drive inverter (DI) is not switching.
|
SDC may trigger the pyro disconnect.
|
No
|
|
|
HVLINK messages are not being received by secondary disconnect controller (SDC).
|
At least one message from HVLINK consumed by SDC is not received.
|
Active discharge control by SDC may be forced ON.
|
No
