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
Engine Light ON (or Service Engine Soon Warning Light)
The motor control module judges the characteristics abnormality of V2S voltage sensor by comparing the voltage control state and V1 voltage reading, V2M voltage reading, and V2S voltage reading. If V2M voltage sensor characteristic abnormalities of the state has continued for the specified time, the motor control module detects a malfunction and stores a DTC.
