B2084	Memory SET switch Indicator Short to Ground	DSM	GO to PINPOINT TEST C .
B2143	Non Volatile Memory Failure (EEPROM)	Continuous	CONFIGURE the DSM. REFER to MODULE CONFIGURATION . CLEAR the DTCs. REPEAT the self-test. If the DTC resets, INSTALL a new DSM. REFER to MULTIFUNCTION ELECTRONIC MODULES . CONFIGURE the DSM.
B2477	Module Configuration Failure	Continuous	INSTALL a new DSM. REFER to MULTIFUNCTION ELECTRONIC MODULES . CONFIGURE the DSM. REFER to MODULE CONFIGURATION .
B2971	Pedal Position Input Short to Ground	DSM	GO to PINPOINT TEST B .
B2972	Pedal Position Input Short to Battery	DSM	GO to PINPOINT TEST B .
U1900	CAN Communication Bus Fault - Receive Error	On-Demand and Continuous	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. If DTC U1900 is present on-demand, CHECK the instrument cluster module for DTCs and REPAIR as needed. REFER to INSTRUMENT CLUSTER . If DTC U1900 is present continuous only, CHECK for an intermittent MS-CAN fault. REFER to MODULE COMMUNICATIONS NETWORK to diagnose the MS-CAN network concern.
U2050	No Application Code Present	On-Demand and Continuous	CONFIGURE the DSM. REFER to MODULE CONFIGURATION . CLEAR the DTC. REPEAT the self-test. If the DTC does not clear or is retrieved again, INSTALL a new DSM. REFER to MULTIFUNCTION ELECTRONIC MODULES . CONFIGURE the DSM.
