AWD Control And Fault Indicators
WARNING: This page is about a different car, the 2023 Lincoln Nautilus. However, it is still accessible from the selected car via links, so may be relevant.
The AWD system consists of a PTU (Power transfer unit), driveshaft, front and rear halfshafts, AWD module, PCM which includes the AWD control logic and an actuator motor located on the RDU. Based on inputs to the PCM, the PCM sends a command to the AWD module. The amount of torque sent to the rear wheels is controlled by the AWD module. AWD system faults are indicated by a driveline icon indicator in the IPC as well as the Check AWD message in the message center.
