PCS2REXA_a114_hvBusEstimatedImpedanceLow

The Power Conversion System (PCS) detects the estimated high voltage (HV) bus impedance is lower than the expected threshold.

Live incidence rate

<0.01% (Extremely rare)

Vehicle messages

None displayed

Impact

The DCDC converter may not precharge the HV bus to its commanded voltage target, preventing HV battery pack contactors from closing.

Cause

The estimated HV bus impedance is lower than the expected threshold.

Clear condition

The DCDC converter is commanded to shut down or receives a new request to precharge the HV bus.
