Answer

It identifies excessive current causing inverter shutdown.

Explain

Overcurrent faults protect the inverter from damage. CHEPQ EV diagnostic tools monitor inverter current, detect short circuits in motor windings, wiring faults, or IGBT/MOSFET failures, and verify current sensor accuracy. This isolates fault sources, preventing inverter damage and ensuring safe drivetrain operation.
