P0602	Powertrain Control Module Programming Error	DEM	CLEAR DTCs. REPEAT the self-test. If DTC P0602 is retrieved, INSTALL a new DEM. REFER to REAR DRIVE AXLE/DIFFERENTIAL . CLEAR the DTCs. REPEAT the self-test.
P0606	ECU Short to Ground or Open Circuit	DEM	CLEAR DTCs. REPEAT the self-test. If DTC P0606 is retrieved, INSTALL a new DEM. REFER to REAR DRIVE AXLE/DIFFERENTIAL . CLEAR the DTCs. REPEAT the self-test.
P0932	Hydraulic Pressure Sensor Circuit	DEM	INSTALL a new Rear Axle Oil Temperature Sensor. REFER to REAR DRIVE AXLE/DIFFERENTIAL . CLEAR the DTC. REPEAT the self-test.
P0937	Hydraulic Oil Temperature Sensor Circuit	DEM	INSTALL a new Rear Axle Oil Temperature Sensor. REFER to REAR DRIVE AXLE/DIFFERENTIAL . CLEAR the DTC. REPEAT the self-test.
P0939	Hydraulic Oil Temperature Sensor Circuit Low Input	DEM	INSTALL a new Rear Axle Oil Temperature Sensor. REFER to REAR DRIVE AXLE/DIFFERENTIAL . CLEAR the DTC. REPEAT the self-test.
P0940	Hydraulic Oil Temperature Sensor Circuit High Input	DEM	INSTALL a new Rear Axle Oil Temperature Sensor. REFER to REAR DRIVE AXLE/DIFFERENTIAL . CLEAR the DTC. REPEAT the self-test.
P0960	Pressure Control Solenoid A Control Circuit Open	DEM	CHECK for damaged rear half-shafts, inner or outer CV joints. MONITOR the ABS wheel speed sensor PIDS to verify that the ABS module is transmitting the correct wheel speeds to the DEM. CHECK for fluid leaks in the active on-demand coupler. REPAIR as necessary. REFER to REAR DRIVE AXLE/DIFFERENTIAL . If no faults are found, INSTALL a new DEM. REFER to REAR DRIVE AXLE/DIFFERENTIAL . CLEAR the DTCs. REPEAT the self-test.
P0961	Pressure Control Solenoid A Control Circuit Range Performance	DEM	CHECK for damaged rear half-shafts, inner or outer CV joints. MONITOR the ABS wheel speed sensor PIDS to verify that the ABS module is transmitting the correct wheel speeds to the DEM. CHECK for fluid leaks in the active on-demand coupler. REPAIR as necessary. REFER to REAR DRIVE AXLE/DIFFERENTIAL . If no faults are found, INSTALL a new DEM. REFER to REAR DRIVE AXLE/DIFFERENTIAL . CLEAR the DTCs. REPEAT the self-test.
P0962	Pressure Control Solenoid A Control Circuit Low	DEM	CHECK for damaged rear half-shafts, inner or outer CV joints. MONITOR the ABS wheel speed sensor PIDS to verify that the ABS module is transmitting the correct wheel speeds to the DEM. CHECK for fluid leaks in the active on-demand coupler. REPAIR as necessary. REFER to REAR DRIVE AXLE/DIFFERENTIAL . If no faults are found, INSTALL a new DEM. REFER to REAR DRIVE AXLE/DIFFERENTIAL . CLEAR the DTCs. REPEAT the self-test.
P1889	Oil Pressure Pump Performance	DEM	INSTALL a new Active On-Demand Coupling Oil Pump. REFER to REAR DRIVE AXLE/DIFFERENTIAL . CLEAR the DTC. REPEAT the self-test. If DTC P1889 is still present, INSTALL the DEM kit (4C016) including all of the parts. REFER to REAR DRIVE AXLE/DIFFERENTIAL . CLEAR the DTCs. REPEAT the self test.
U0001	High Speed CAN Communication Bus	DEM	REFER to MODULE COMMUNICATIONS NETWORK .
U0121	Lost Communication With Anti-Lock Brake System (ABS) Control Module (One or More Wheel Speeds Missing)	DEM	REFER to MODULE COMMUNICATIONS NETWORK .
U2050	No Valid Application Added	DEM	RECONFIGURE the DEM using As-Built Data.
