Description
The Power Conversion System (PCS) electronic control unit (ECU) detects the DCDC tank current period is too long, indicating the DCDC metal-oxide-semiconductor field-effect transistor (MOSFETs) are not switching properly.
Condition
The PCS ECU detects the DCDC MOSFETs are not switching properly.
