Module Communications Network DTCS: BCM

DTC CHART: BCM

DTC	Description	Action
U0004	High Speed CAN Communication Bus (+) Low: No Sub Type Information	A High Speed Controller Area Network (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 for additional information.
U0005	High Speed CAN Communication Bus (+) High: No Sub Type Information	A High Speed Controller Area Network (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 AA
U0007	High Speed CAN Communication Bus (-) Low: No Sub Type Information	A High Speed Controller Area Network (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 AA
U0008	High Speed CAN Communication Bus (-) High: No Sub Type Information	A High Speed Controller Area Network (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 for additional information.
U0009	High Speed CAN Communication Bus (-) Shorted to Bus (+): No Sub Type Information	A High Speed Controller Area Network (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 for additional information.
U0013	Medium Speed CAN Communication Bus (+) Low: No Sub Type Information	A Medium Speed Controller Area Network (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 High Speed Controller Area Network (HS-CAN). If no Medium Speed Controller Area Network (MS-CAN) modules communicate, GO to PINPOINT TEST AC If all Medium Speed Controller Area Network (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 for additional information.
U0014	Medium Speed CAN Communication Bus (+) High: No Sub Type Information	A Medium Speed Controller Area Network (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 AC
U0016	Medium Speed CAN Communication Bus (-) Low: No Sub Type Information	A Medium Speed Controller Area Network (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 AC
U0017	Medium Speed CAN Communication Bus(-) High: No Sub Type Information	A Medium Speed Controller Area Network (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 High Speed Controller Area Network (HS-CAN). If no Medium Speed Controller Area Network (MS-CAN) modules communicate, GO to PINPOINT TEST AC If all Medium Speed Controller Area Network (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 for additional information.
U0018	Medium Speed CAN Communication Bus (-) Shorted to Bus (+): No Sub Type Information	A Medium Speed Controller Area Network (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. Refer to SYSTEM WIRING DIAGRAMS for additional information.
