Refer to Wiring Diagrams Cell 34 for schematic and connector information. Normal Operation and Fault Conditions The rear drive unit contains a three phase reversible motor. The motor actuates a clutch in the RDU to enable or disable AWD . The AWD module controls the motor by supplying power on the RDMC X circuits. The motor position is communicated back to the AWD module on the RDMP X circuits. When the AWD module powers up, the AWD Module will cycle the motor from hard stop (clutch fully released) to the clutch kiss point. The kiss point is the maximum clutch apply point where 0 torque is transmitted through the clutch. DTC Fault Trigger Conditions

Did C0092:92 set in the continuous memory.

Normal Operation and Fault Conditions The RDU contains an actuator motor, ball ramp, and a multi-plate clutch pack. During manufacturing, the frictional characteristics of the clutch are measured and recorded in a database for each RDU serial number. New AWD modules will need this data programmed to configure the RDU performance characteristics. The AWD module checks the value stored in memory upon key up. If the value is missing or not valid, a DTC will be stored and limited AWD functionality will be present. The AWD - Active Torque Coupling Configuration routine will have the technician manually enter the 16 digit alpha numeric serial number from the label on the RDU into the diagnostic scan tool. The scan tool will search the database for the serial number and program the AWD module with the clutch characteristics data from manufacturing. DTC Fault Trigger Conditions

Refer to Wiring Diagrams Cell 14 for schematic and connector information. Refer to Wiring Diagrams Cell 34 for schematic and connector information. Normal Operation and Fault Conditions The AWD module expects to receive network data from other modules on HS-CAN1 . The AWD module will set a DTC when it receives an invalid or incomplete messages from another module. Incomplete or corrupted messages typically result from high network traffic preventing the complete message from being received within the calibrated time limit. Invalid data messages typically result from a fault with the suspect module or system. DTC Fault Trigger Conditions
