The SH-AWD control system consists of a SH-AWD control unit, the PCM, the VSA modulator-control unit, along with various sensors and switches that detect the steering angle, the lateral G force, the yaw, and the vehicle speed A fluid temperature sensor is located on the rear differential The control units exchange information via the CAN communication lines The SH-AWD control unit has a self-diagnostic function If a malfunction is detected, the SH-AWD control unit turns on the SH-AWD indicator in the gauge control module, and the system goes into fail-safe mode When in fail-sate mode, the vehicle disables the SH-AWD differential The vehicle defaults to front wheel drive and reduces engine torque to suit the driving conditions
