DTC P1A54: General Description

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

The power control unit (PCU) controls the motor output based on the motor phase current sensor signals. When the motor control module in the PCU malfunctions, there is a possibility that the motor torque cannot be controlled properly. If the difference between the target motor torque and the estimated motor torque is out of a specified value, the motor control module detects a malfunction and stores a DTC.
