P1DA6 ACURA Description

  The motor control module judges the characteristics abnormality of V1 voltage sensor by comparing the voltage control state and V1 voltage reading, battery voltage reading, and V2 voltage reading. Furthermore, in V1 overcurrent range, the gate is shut for Voltage Control Unit (VCU), and malfunction detection of the three voltages cannot be performed which causes to stop the fluctuation of the V1 voltage reading, so the motor control module detects a malfunction and stores a DTC.
