P1DA2 Honda Code - Voltage Control Unit Low Side Open Fail
Quick Answer
If the low side of Voltage Control Unit (VCU) has open-malfunction, the V2 voltage drops because voltage increase control cannot be performed as commanded, so the VCU low side is judged as abnormal output, and the motor control module (generator) detects a malfunction and stores a DTC. 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.
