| Signal Name | Description | Condition | Impact |
|---|---|---|---|
|
FC contactor opened unexpectedly due to insufficient contactor drive voltage.
|
Contactor control state exited CLOSED because of insufficient contactor power voltage.
|
Vehicle will stop charging.
|
|
|
FC contactor exited the economized state unexpectedly. Possibly insufficient coil drive current.
|
Contactor control state exited CLOSED because either of the contactors exited ECONOMIZED.
|
Vehicle will stop charging.
|
|
|
Tried to close FC contactors but failed because a voltage match was not maintained.
|
Contactor control state exited CLOSING due to voltage match being lost.
|
FC contactors will remain open.
|
|
|
Sets immediately on SPI comms errors for visibility into the health of the comms interface.
|
Communication error with the shunt asic on single SPI
|
ShuntAsicFault is at risk of being triggered soon
|
|
|
Warns if the shunt current (discharge or charge) is above max current limit.
|
The shunt current (discharge or charge) is above max current limit.
|
The pack contactors will fast interrupt
|
|
|
Passive reference is out-of-tolerance.
|
Passive reference is out-of-tolerance
|
Passive thresholds are affected
|
|
|
Shunt bar temperature is too high.
|
Shunt bar temperature is too high
|
Battery pack HV will be blocked. Shunt may become physically damaged.
|
|
|
The shunt thermistor is not reporting as expected. Vehicle may be unable to drive or DC charge.
|
Shunt thermistor reading is open circuit.
|
Vehicle may be unable to drive. DC charging may be limited or unavailable.
|
|
|
The shunt measurement asic has a SPI communication fault or other internal fault.
|
Fault condition was set during SPI communications
|
Shunt readings are stale
|
|
|
The shunt measurement ASIC is not producing data.
|
Timeout on expected communication
|
Shunt readings are stale
|
|
|
FC contactors were blocked from opening due to high current. Pyro deployed instead.
|
Charge current is above threshold while trying to open FC contactors.
|
The positive and negative pyro fuses will be deployed.
|
|
|
The shunt thermal coefficient of resistance (TCR) calibrations are not being used for high voltage (HV) current sensing. The default shunt TCR coefficients will be used and current measurement accuracy may be reduced.
|
The stored shunt bar resistance is invalid or the written gain is outside the allowed tolerance.
|
The default shunt TCR coefficients will be used for high voltage (HV) current sensing. Shunt current measurement accuracy may be reduced.
|
|
|
The programmed shunt bar resistance calibration is not being used for high voltage (HV) current sensing. The default shunt bar resistance will be used and current measurement accuracy may be reduced.
|
The stored shunt bar resistance is invalid or the written gain is outside the allowed tolerance.
|
The default shunt bar resistance will be used for high voltage (HV) current sensing. Shunt current measurement accuracy may be reduced.
|
|
|
Positive contactor is expected to be open but the voltage match remains. Possible weld detected.
|
Contactor state timed out of OPENING (and transitioned to AUX_MISMATCH) due to a weld not having been disqualified.
|
The pyro fuse may be deployed.
|
|
|
The programmed shunt application-specific integrated circuit (ASIC) calibration is not being used for high voltage (HV) current sensing. The default shunt ASIC gain will be used and current measurement accuracy may be reduced.
|
The stored shunt ASIC gain is invalid or the written gain is outside the allowed tolerance.
|
The default shunt ASIC gain will be used for high voltage (HV) current sensing. Shunt current measurement accuracy may be reduced.
|
|
|
A communication interruption has been detected in the Battery Monitoring Board (BMB) chain.
|
A communication issue with the BMB daisy chain is detected
|
May indicate a loss of BMB sensor data
|
|
|
Data integrity loss due to Battery Monitoring Board (BMB) chain double break.
|
A prolonged communication issue with the BMB daisy chain that is known to cause a loss of BMB sensor data is detected
|
BMB sensor data is likely being substituted to replace data missing due to the communication issue
|
|
|
High voltage isolation is too low for the pack to be online.
|
Isolation is measured to be below the alert threshold while pack contactors are closed
|
Pack may not come online
|
|
|
Measurement of internal isolation (within the pack) is too low.
|
Internal isolation is measured to be below the alert threshold
|
Pack may not come online
|
|
|
Incorrect, missing, or unsupported board part number programmed.
|
ECU detects an unexpected board part number
|
ECU is unable to initialize parameters related to printed circuit board assembly (PCBA) configuration
