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 Programmable Module Installation (PMI) on the DSM
. REFER to
MODULE CONFIGURATION
. REPEAT the self-test and VERIFY successful PMI
. If successful, the DTC will not be present. |
| U0140 | Lost Communication With Body Control Module (GEM ) | Continuous | CLEAR the DTC. REPEAT the self-test. If the DTC is retrieved again, REFER to MODULE COMMUNICATIONS NETWORK to diagnose the Medium Speed Controller Area Network (MS-CAN) concern. |
| U0155 | Lost Communication With Instrument Panel Cluster Instrument Cluster (IC) Module | Continuous | CLEAR the DTC. REPEAT the self-test. If the DTC is retrieved again, REFER to MODULE COMMUNICATIONS NETWORK to diagnose the MS-CAN concern. |
| U2050 | Application Not Present | Continuous | INSTALL a new DSM and CARRY OUT Programmable Module Installation (PMI). REFER to MULTIFUNCTION ELECTRONIC MODULES . REPEAT the self-test. |
| All Other DTCs | - | - | REFER to the Master DTC Chart in MULTIFUNCTION ELECTRONIC MODULES . |
