DTC	Description	Action
P0A12:16	DC/DC Converter Enable Circuit Low: Circuit Voltage Below Threshold	GO to PINPOINT TEST A .
P0A94:4B	DC/DC Converter Performance: Over Temperature	GO to PINPOINT TEST B .
P0AF7:00	14 Volt Power Module Internal Temperature Too High: No Sub Type Information	GO to PINPOINT TEST C .
P0AFA:13	Hybrid Battery System Voltage Low: Circuit Open	GO to PINPOINT TEST D .
P0AFA:16	Hybrid Battery System Voltage Low: Circuit Voltage Below Threshold	GO to PINPOINT TEST E .
P0AFB:17	Hybrid Battery System Voltage High: Circuit Voltage Above Threshold	GO to PINPOINT TEST F .
U0001:88	High Speed Controller Area Network (HS-CAN) Communication Bus: Bus Off	The DC to DC Converter Control Module (DC/DC) could not communicate on the network at a point in time. The fault is currently not present. CLEAR the DTC. REPEAT the Network Test with the scan tool. REFER to MODULE COMMUNICATIONS NETWORK -- FUSION, MILAN & MKZ article for further diagnosis as needed.
U0100:00	Lost Communication With ECM/PCM "A": No Sub Type Information	REFER to MODULE COMMUNICATIONS NETWORK -- FUSION, MILAN & MKZ article to diagnose lost PCM communication.
U0101:00	Lost Communication With TCM: No Sub Type Information	REFER to MODULE COMMUNICATIONS NETWORK -- FUSION, MILAN & MKZ article to diagnose lost Transmission Control Module (TCM) communication.
U0155:00	Lost Communication With Instrument Panel Cluster (IPC) Control Module: No Sub Type Information	REFER to MODULE COMMUNICATIONS NETWORK -- FUSION, MILAN & MKZ article to diagnose lost IPC module communication.
U0300:00	Internal Control Module Software Incompatibility: No Sub Type Information	DIAGNOSE any other DC/DC DTCs first. If no other DC/DC DTCs are present, GO to PINPOINT TEST G .
U0401:68	Invalid Data Received From ECM/PCM A: Event Information	NOTE: DTC U0401:68 indicates a HS-CAN message from the PCM is outside normal limits due to a faulty PCM input. REVIEW freeze frame data for DTC U0401:68 to determine if the fault pertains to the Motor Electronics Cooling System (MECS) coolant temperature sensor, ambient air temperature or vehicle voltage. RETRIEVE PCM DTCs and DIAGNOSE any DTCs related to MECS coolant temperature sensor, ambient air temperature or vehicle voltage. REFER to INTRODUCTION - GASOLINE MODELS article or INTRODUCTION -- FUSION HYBRID, MILAN HYBRID & MKZ HYBRID article for further diagnosis.
U0402:68	Invalid Data Received From TCM: Event Information	NOTE: DTC U0402:68 indicates a HS-CAN message from the TCM is outside normal limits due to a faulty TCM input. RETRIEVE TCM DTCs and DIAGNOSE any DTCs related to high-voltage input. REFER to INTRODUCTION - GASOLINE MODELS article or INTRODUCTION -- FUSION HYBRID, MILAN HYBRID & MKZ HYBRID article for further diagnosis.
U3000:04	Control Module: System Internal Failure	CLEAR the DTC. REPEAT the self-test. If the DTC is still present, INSTALL a new DC/DC.
U3000:41	Control Module: General Checksum Failure	DIAGNOSE any other DC/DC DTCs first. If no other DTCs are present, CLEAR the DTC. REPEAT the self-test. If the DTC is still present, INSTALL a new DC/DC. REFER to DIRECT CURRENT/DIRECT CURRENT (DC/DC) CONVERTER in this service information.
U3000:42	Control Module: General Memory Failure	DIAGNOSE any other DC/DC DTCs first. If no other DTCs are present, CLEAR the DTC. REPEAT the self-test. If the DTC is still present, INSTALL a new DC/DC. REFER to DIRECT CURRENT/DIRECT CURRENT (DC/DC) CONVERTER in this service information.
U3000:45	Control Module: Program Memory Failure	DIAGNOSE any other DC/DC DTCs first. If no other DTCs are present, CLEAR the DTC. REPEAT the self-test. If the DTC is still present, INSTALL a new DC/DC. REFER to DIRECT CURRENT/DIRECT CURRENT (DC/DC) CONVERTER in this service information.
U3000:49	Control Module: Internal Electronic Failure	If the 12V battery is on a charger, REMOVE the charger. CLEAR the DTC. REPEAT the self-test. If DTC U3003:49 returns, INSTALL a new DC/DC. REFER to DIRECT CURRENT/DIRECT CURRENT (DC/DC) CONVERTER in this service information.
U3000:96	Control Module: Component Internal Failure	CLEAR the DTC. REPEAT the self-test. REFER to DIRECT CURRENT/DIRECT CURRENT (DC/DC) CONVERTER in this service information. If the DTC is still present, INSTALL a new DC/DC.
U3003:16	Battery Voltage: Circuit Voltage Below Threshold	GO to PINPOINT TEST H .
U3003:17	Battery Voltage: Circuit Voltage Above Threshold	GO to PINPOINT TEST I .
U3003:62	Battery Voltage: Signal Compare Failure	GO to PINPOINT TEST J .
