| U0029 | - | Vehicle Communication Bus A Performance | -- Check the CAN Bus. Refer to CAN BUS TERMINAL RESISTANCE, CHECKING . |
| U0101 | 28773 | Lost Communication with TCM | Check TCM communication with a scan tool. If no TCM communication with scan tool and all other modules communicate, check TCM power and grounds. If OK, replace TCM Module. |
| U102C | - | Lost Communication With Anti-Lock Brake System (ABS) Control Module | Check ABS communication with a scan tool. If no ABS communication with scan tool and all other modules communicate, check ABS power and grounds. If OK, replace ABS Module. |
| U0121 | 28793 | Lost Communication With Anti-Lock Brake System (ABS) Control Module | Check ABS communication with a scan tool. If no ABS communication with scan tool and all other modules communicate, check ABS power and grounds. If OK, replace ABS Module. |
| U0146 | 28818 | Lost Communication With Gateway "A" | Check Gateway communication with a scan tool. If no Gateway communication with scan tool and all other modules communicate, check Gateway power and grounds. If OK, replace Gateway Module. |
| U0155 | 28827 | Lost Communication With Instrument Panel Cluster (IPC) Control Module | Check IPC communication with a scan tool. If no IPC communication with scan tool and all other modules communicate, check IPC power and grounds. If OK, replace IPC Module. |
| U0302 | 28974 | Software Incompatibility with Transmission Control Module | Check for correct software in ECM and TCM. If software is incorrect, reflash module with correct software. |
| U0402 | 29074 | Invalid Data Received From Transmission Control Module | May have VIN error. Check VIN in each module for correct data |
| U0415 | 29087 | Invalid Data Received From Anti-Lock Brake System Control Module | May have vehicle speed error. Using a scan tool, check for correct vehicle speed reading from wheel sensors in ABS module. If an ABS fault (DTC) exists, refer to the ABS Diagnosis in the Repair Information. |
| U0423 | - | Invalid Data Received From Instrument Panel Cluster Control Module | May have VIN error. Check VIN in each module for correct data |
| U1006 | - | NOX Sensor No Communication | -- Check the Nox Sensor -G295-. Refer to NOX SENSOR / MODULE, CHECKING . |
| U1024 | - | Instrument cluster control module Read out DTC | -- Check the CAN Bus. Refer to CAN BUS TERMINAL RESISTANCE, CHECKING . Check IPC communication with a scan tool. If no IPC or intermittent communication with scan tool exists and all other modules communicate with tool, check IPC connectors and terminals for spread or loose connection. Check power and grounds. If above check results are OK, replace IPC Module. |
| U1034 | - | NOx Sensor 1 Implausible Signal | -- Check the Nox Sensor -G295-. Refer to NOX SENSOR / MODULE, CHECKING . |
