P1F3D Acura Code - Voltage Control Unit Circuit Malfunction High
Quick Answer
The motor control module (generator) receives IGBT high side short-circuit information detected by the Voltage Control Unit (VCU) via serial communication and detects a malfunction and stores a DTC when the information is received continuously for the prescribed time or more. Common causes include Faulty Voltage Control Unit, Voltage Control Unit harness is open or shorted, Voltage Control Unit 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.
