C05DD4WD/AWD Clutch A Performance/Stuck Disengaged

This code indicates that the four-wheel-drive (4WD) or all-wheel-drive (AWD) control module has detected a performance problem with clutch 'A', typically the main coupling clutch that engages the rear axle, and it has determined that the clutch is stuck in the disengaged position. The computer commands the clutch to engage and monitors the resulting speed difference between the front and rear wheels, and when the expected engagement does not occur within a calibrated time, it sets this code.
