Module Communications Network DTCS

BODY CONTROL MODULE (BCM) DTC CHART

DTCs	Description	Action
U0004	High Speed CAN Communication Bus (+) Low: No Sub Type Information	A HS-CAN fault was present at a point in time. The fault is not currently present since the module is communicating with the scan tool. CLEAR the DTC. REPEAT the network test with the scan tool. VERIFY the integrity of the connectors and wiring. Refer to SYSTEM WIRING DIAGRAMS - Module Communications Network for additional information.
U0005	High Speed CAN Communication Bus (+) High: No Sub Type Information	A HS-CAN fault is present but the network may still be functional at a degraded level. One or more modules may not communicate and may not be sending or receiving messages. GO to PINPOINT TEST Z .
U0007	High Speed CAN Communication Bus (-) Low: No Sub Type Information	A HS-CAN fault is present but the network may still be functional at a degraded level. One or more modules may not communicate and may not be sending or receiving messages. GO to PINPOINT TEST Z .
U0008	High Speed CAN Communication Bus (-) High: No Sub Type Information	A HS-CAN fault was present at a point in time. The fault is not currently present since the module is communicating with the scan tool. CLEAR the DTC. REPEAT the network test with the scan tool. VERIFY the integrity of the connectors and wiring. Refer to SYSTEM WIRING DIAGRAMS - Module Communications Network for additional information.
U0009	High Speed CAN Communication Bus (-) Shorted to Bus (+): No Sub Type Information	A HS-CAN fault was present at a point in time. The fault is not currently present since the module is communicating with the scan tool. CLEAR the DTC. REPEAT the network test with the scan tool. VERIFY the integrity of the connectors and wiring. Refer to SYSTEM WIRING DIAGRAMS - Module Communications Network for additional information.
U0013	Medium Speed CAN Communication Bus (+) Low: No Sub Type Information	A MS-CAN fault is either currently present or was present at a point in time. The BCM can report this DTC while a fault is present because the BCM communicates with the scan tool on the HS-CAN. If no MS-CAN modules communicate, GO to PINPOINT TEST AA . If all MS-CAN modules currently communicate, CLEAR the DTC. REPEAT the network test with the scan tool. VERIFY the integrity of the connectors and wiring. Refer to SYSTEM WIRING DIAGRAMS - Module Communications Network for additional information.
U0014	Medium Speed CAN Communication Bus (+) High: No Sub Type Information	A MS-CAN fault is present but the network may still be functional at a degraded level. One or more modules may not communicate and may not be sending or receiving messages. GO to PINPOINT TEST AA .
U0016	Medium Speed CAN Communication Bus (-) Low: No Sub Type Information	A MS-CAN fault is present but the network may still be functional at a degraded level. One or more modules may not communicate and may not be sending or receiving messages. GO to PINPOINT TEST AA .
U0017	Medium Speed CAN Communication Bus(-) High: No Sub Type Information	A MS-CAN fault is either currently present or was present at a point in time. The BCM can report this DTC while a fault is present because the BCM communicates with the scan tool on the HS-CAN. If no MS-CAN modules communicate, GO to PINPOINT TEST AA . If all MS-CAN modules currently communicate, CLEAR the DTC. REPEAT the network test with the scan tool. VERIFY the integrity of the connectors and wiring. Refer to SYSTEM WIRING DIAGRAMS - Module Communications Network for additional information.
U0018	Medium Speed CAN Communication Bus (-) Shorted to Bus (+): No Sub Type Information	A MS-CAN fault was present at a point in time. The fault is not currently present since the module is communicating with the scan tool. CLEAR the DTC. REPEAT the network test with the scan tool. VERIFY the integrity of the connectors and wiring.
