GHH388683Courtesy of HONDA, U.S.A., INC.

The power control unit (PCU) monitors the IGBT chip temperature sensor values to prevent malfunctions of the chip and other parts due to heat generation. The PCU calculates the difference in output temperature between the parallel phases of the IGBT chip temperature sensor at the traction motor side. If the difference is out of a specified value for a specified time, the motor control module in the PCU detects a malfunction and stores a DTC.
