P1DA6 Acura Code - Voltage Control Unit V1 Voltage Sensor Range/Performance

Quick Answer

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. Common causes include Faulty Voltage Control Unit (VCU), Voltage Control Unit (VCU) harness is open or shorted, Voltage Control Unit (VCU) circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code 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.
