| B2143 | Non Volatile Memory Failure (EEPROM) | Continuous | REPEAT the self-test. CLEAR the DTCs. If the DTC resets, INSTALL a new DSM and CARRY OUT PMI. REFER to MULTIFUNCTION ELECTRONIC MODULES article. REPEAT the self-test. |
| B2477 | Module Configuration Failure | Continuous |
NOTE:
This DTC indicates PMI has not been done to a newly installed module or configuration data has been lost. Presence of this DTC alone does not prevent basic seat operation from the seat control switch. CARRY OUT PMI on the DSM. REFER to MODULE CONFIGURATION
article. REPEAT the self-test. If PMI is successful, the DTC will not be present. |

NOTE:
Do not install a new DSM as part of repair for a DSM DTC U1900 fault. The DSM is not the source of the fault when DTC U1900 is present. CLEAR the DTC. REPEAT the self-test. If the DTC is retrieved again, REFER to MODULE COMMUNICATIONS NETWORK
article to diagnose the medium-speed communication area network (MS-CAN) concern. |
| U2050 | No Application Present | Continuous | INSTALL a new DSM and CARRY OUT PMI. REFER to MULTIFUNCTION ELECTRONIC MODULES article. REPEAT the self-test. |
