Courtesy of HONDA, U.S.A., INC.

The power control unit (PCU) detects the traction motor temperature with a traction motor temperature sensor installed in the traction motor. The motor control module in the PCU detects a malfunction and stores a DTC when the traction motor temperature sensor value does not change from the initial value continuously for the prescribed time though the traction motor is under load.
