Circuit/System Description
The rear differential clutch control module (CCM) provides a power and ground switching circuits to the solenoid. The solenoid receives current from the CCM through PWM low side driver, and converts that signal into torque through the clutch to the rear tires when all wheel drive (AWD) is requested.
The rear differential clutch control module (CCM) provides a power and ground circuits to the temperature sensor. When the temperature of the module is determined to be beyond its limits, the CCM will temporarily disable the rear drive system.
The rear differential clutch control module (CCM) detects an internal malfunction.
The rear differential clutch control module (CCM) is required to have the correct calibration data (matching ID) stored in the memory from the AWD coupling control, and is part of the programming used to perform all wheel drive functions.
The rear differential clutch control module (CCM) receives messages from other modules over serial data which are needed to perform all wheel drive functions.
