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
Wiring Diagrams Cell 14 for schematic and connector 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 AD |
| 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 AD |

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
Wiring Diagrams Cell 14 for schematic and connector information. |

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 SYSTEM WIRING DIAGRAMS
Wiring Diagrams Cell 14 for schematic and connector information. |
