DTC P1A88: General Description

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

The power control unit (PCU) controls the voltage control unit (VCU) output based on the V1 voltage sensor signals. When the difference in voltages compared during self-diagnosis (with the C1C0 directly connected) is a specified value or more and continues for a specified duration or more, the motor control module in the PCU detects a malfunction and stores a DTC.
