C05D84WD/AWD Clutch A Actuator Control Circuit/Open

  • Generic OBD-II code · Chassis
  • Can trigger limp mode
How the car detects it
The AWD controller sees no plausible current path in the output that drives the actuator of clutch A, typically an open coil, motor winding or wire. Depending on the design, the actuator is an electromagnetic coil (JTEKT ITCC: coil current sets the transmitted torque) or an electric motor that turns a ball ramp through a worm gear, as in a Magna disconnect coupling. Ford names C05D8:19 for the Bronco Sport with the 2.0L engine, model years 2021–2022, in SSM 51117, together with C05D9:71 and the clutch B codes C05E7/C05E8; the cause there is a misaligned magnet ring in the rear drive unit motor, fixed by replacing the motor alone. With the circuit open the clutch cannot close, AWD is switched off and a warning appears.
