DTC Charts

WARNING: This page is about a different car, the 2012 Ford Fiesta. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Network DTCs (U-codes) are often a result of intermittent concerns such as damaged wiring or low battery voltage occurrences. Additionally, repair procedures such as module reprogramming often set network DTCs. Replacing a module to resolve a network DTC is unlikely to correct the concern. To prevent repeat network DTC concerns, inspect all network wiring, especially connectors. Test the vehicle battery, refer to BATTERY, MOUNTING AND CABLES .

COMMUNICATION NETWORK DTC CHART

DTC	Description	Source	Action
U0001:00	High Speed Controller Area Network (HS-CAN) Communication Bus: no subtype information	RFA	The module could not communicate on the network at a point in time. The fault is not currently present (the module had to communicate with the scan tool to report this DTC). CLEAR the DTC. REPEAT the network test with the scan tool. VERIFY the integrity of the connectors and wiring Refer to OEM WIRING DIAGRAMS - MODULE COMMUNICATIONS NETWORK for schematic and connector information.
U0001:88	High Speed Controller Area Network (HS-CAN) Communication Bus	ABS module PSCM PCM	The module could not communicate on the network at a point in time. The fault is not currently present (the module had to communicate with the scan tool to report this DTC). CLEAR the DTC. REPEAT the network test with the scan tool. VERIFY the integrity of the connectors and wiring Refer to OEM WIRING DIAGRAMS - MODULE COMMUNICATIONS NETWORK for schematic and connector information.
U0002:81	High Speed Controller Area Network (HS-CAN) Communication Bus Performance	PCM	The module could not communicate on the network at a point in time. The fault is not currently present (the module had to communicate with the scan tool to report this DTC). CLEAR the DTC. REPEAT the network test with the scan tool. VERIFY the integrity of the connectors and wiring Refer to OEM WIRING DIAGRAMS - MODULE COMMUNICATIONS NETWORK for schematic and connector information.
U0010:00	Medium Speed Controller Area Network (MS-CAN) Communication Bus: no subtype information	RFA	The module could not communicate on the network at a point in time. The fault is not currently present (the module had to communicate with the scan tool to report this DTC). CLEAR the DTC. REPEAT the network test with the scan tool. VERIFY the integrity of the connectors and wiring Refer to OEM WIRING DIAGRAMS - MODULE COMMUNICATIONS NETWORK for schematic and connector information.
U0010:88	Medium Speed Controller Area Network (MS-CAN) Communication Bus	BCM FCDIM	The module could not communicate on the network at a point in time. The fault is not currently present (the module had to communicate with the scan tool to report this DTC). CLEAR the DTC. REPEAT the network test with the scan tool. VERIFY the integrity of the connectors and wiring Refer to OEM WIRING DIAGRAMS - MODULE COMMUNICATIONS NETWORK for schematic and connector information.
U0028:00	Vehicle Communication Bus A	TCM	The module could not communicate on the network at a point in time. The fault is not currently present (the module had to communicate with the scan tool to report this DTC). CLEAR the DTC. REPEAT the network test with the scan tool. VERIFY the integrity of the connectors and wiring Refer to OEM WIRING DIAGRAMS - MODULE COMMUNICATIONS NETWORK for schematic and connector information.
U0028:08	Vehicle Communication Bus A: Bus Signal/Message Failures	RCM	The module could not communicate on the network at a point in time. The fault is not currently present (the module had to communicate with the scan tool to report this DTC). CLEAR the DTC. REPEAT the network test with the scan tool. VERIFY the integrity of the connectors and wiring Refer to OEM WIRING DIAGRAMS - MODULE COMMUNICATIONS NETWORK for schematic and connector information.
U0028:88	Vehicle Communication Bus A: Bus Off	RCM	The module could not communicate on the network at a point in time. The fault is not currently present (the module had to communicate with the scan tool to report this DTC). CLEAR the DTC. REPEAT the network test with the scan tool. VERIFY the integrity of the connectors and wiring Refer to OEM WIRING DIAGRAMS - MODULE COMMUNICATIONS NETWORK for schematic and connector information.
U0073:00	Control Module Communication Bus "A" Off	TCM	The module could not communicate on the network at a point in time. The fault is not currently present (the module had to communicate with the scan tool to report this DTC). CLEAR the DTC. REPEAT the network test with the scan tool. VERIFY the integrity of the connectors and wiring Refer to OEM WIRING DIAGRAMS - MODULE COMMUNICATIONS NETWORK for schematic and connector information.
U0074:88	Infotainment Controller Area Network (I-CAN) Communication Bus	FCDIM	The module could not communicate on the network at a point in time. The fault is not currently present (the module had to communicate with the scan tool to report this DTC). CLEAR the DTC. REPEAT the network test with the scan tool. VERIFY the integrity of the connectors and wiring Refer to OEM WIRING DIAGRAMS - MODULE COMMUNICATIONS NETWORK for schematic and connector information.
U3000:88	Control Module: Bus Off	APIM	The module could not communicate on the network at a point in time. The fault is currently not present since the module is currently communicating with the scan tool reporting this DTC. CLEAR the DTC. REPEAT the network test with the scan tool. VERIFY the integrity of the connectors and wiring Refer to OEM WIRING DIAGRAMS - MODULE COMMUNICATIONS NETWORK for schematic and connector information.
