Module Communications Network DTCS: BCM

DTC INDEX

DTC Description Action
U0001:88 High Speed CAN Communication Bus: Bus Off 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 diagnostic scan tool. CLEAR the DTC. REPEAT the network test with the diagnostic scan tool. VERIFY the integrity of the connectors and wiring. Refer to Module Communications Network for schematic and connector information.
U0004:00 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 Module Communications Network for schematic and connector information.
U0005:00 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 AD
U0007:00 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 AD
U0008:00 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 Module Communications Network for schematic and connector information.
U0009:00 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 Module Communications Network for schematic and connector information.
U0010:88 Medium Speed CAN Communication Bus: Bus Off 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 diagnostic scan tool. CLEAR the DTC. REPEAT the network test with the diagnostic scan tool. VERIFY the integrity of the connectors and wiring. Refer to Module Communications Network for schematic and connector information.
U0013:00 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 AF 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 Module Communications Network for schematic and connector information.
U0014:00 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 AF
U0016:00 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 AF
U0017:00 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 AF 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 Module Communications Network for schematic and connector information.
U0018:00 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 Module Communications Network for schematic and connector information.
