P1DA7 HONDA Possible Causes

Faulty Voltage Control Unit (VCU),Voltage Control Unit (VCU) harness is open or shorted,Voltage Control Unit (VCU) circuit poor electrical connection,Faulty Motor Control Module

P1DA7 HONDA Description

The motor control module controls the voltage of motor control module based on voltage sensor signal from the Voltage Control Unit (VCU). If the detected value of the output voltage V2PL, V2NL from the voltage sensor is less than the specified value and continues to be so for a set time, the motor control module detects a malfunction and stores a DTC.
