DTC P1D18: General Description

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

The power control unit (PCU) monitors the IGBT chip temperature sensor value to prevent malfunction of the chip due to heat generation. The PCU detects the IGBT chip temperature sensor at the traction motor side by selecting a parallel phase temperature using the selector. If a selection signal is not switched for the specified time, the motor control module in the PCU detects a malfunction and stores a DTC.
