| 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.

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. |
