P0940	Hydraulic Oil Temperature Sensor Circuit High Input	DEM	INSTALL a new Rear Axle Oil Temperature Sensor. REFER to REAR DRIVE AXLE AND DIFFERENTIAL . CLEAR the DTC. REPEAT the self-test.
P0960	Pressure Control Solenoid A Control Circuit Open	DEM	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 REMOVAL AND INSTALLATION . If no faults are found, INSTALL a new DEM. REFER to INSTALLATION . CLEAR the DTCs. REPEAT the self-test.
P0961 DEM code only (code can appear in TCM)	Pressure Control Solenoid A Control Circuit Range Performance	DEM	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 REMOVAL AND INSTALLATION . If no faults are found, INSTALL a new DEM. REFER to INSTALLATION . CLEAR the DTCs. REPEAT the self-test.
P0962	Pressure Control Solenoid A Control Circuit Low	DEM	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 REMOVAL AND INSTALLATION . If no faults are found, INSTALL a new DEM. REFER to INSTALLATION . CLEAR the DTCs. REPEAT the self-test.
P1889	Oil Pressure Pump Performance	DEM	INSTALL a new Active On-Demand Coupling Oil Pump. REFER to REMOVAL AND INSTALLATION . 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 INSTALLATION . CLEAR the DTCs. REPEAT the self test.
