Acura’s SH-AWD System: AWD Performance Leader

acceleration device (on RL models only) is bolted to the front of the electronically controlled differential. It consists of a control solenoid, a high clutch, a one- way clutch, a planetary gearset, and an oil pump. The acceleration device allows the rear wheels to be variably overdriven by as much as 5.7% faster than the front wheels, depending on driving conditions. • SH-AWD Control Module: The

SH-AWD control module controls the AWD system. It uses information from several different systems to control AWD operation.

How the SH-AWD

System Operates

The SH-AWD system is controlled

by the SH-AWD control module. The SH-AWD control module receives infor- mation through the CAN system from these sources (figure 2): • Powertrain Control Module (PCM) • Antilock Brake System (ABS) • Vehicle Stability Assist System (VSA) • Electronic Brake Force Distribution Module (EBFD) • Throttle Control System • Yaw Angle Sensor
