C05DA4WD/AWD Clutch A Actuator Control Circuit Low
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- The voltage measured on the clutch A actuator line stays below the expected level, which usually means a short to ground somewhere between the control module and the coil or motor. Mitsubishi Electric describes a method for an electromagnetic driveline clutch: a high-side PWM transistor and a low-side switch feed the coil, the terminal voltages are compared with their normal values, and on a ground fault both transistors switch off so the clutch opens. JTEKT's ITCC likewise sets its clutch force through coil current, and BorgWarner also offers electromagnetically actuated couplings. No manufacturer publishes a case for C05DA. C05DB covers the opposite fault, a short to supply; C05D8 an open circuit.
