C05DB4WD/AWD Clutch A Actuator Control Circuit High
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- Set when the clutch A actuator line reads too high, typically because it touches battery voltage or because the low-side switch cannot pull it down. For an electromagnetic clutch, Mitsubishi Electric checks for this short with the selector in P or N by comparing the terminal voltages against normal values, then releases the clutch by turning off both drivers. A line stuck at supply can keep a coil partly energized, so on an ITCC-type coupling (current controls torque) the clutch may drag even when open is commanded. Newer BorgWarner couplings instead use a brushless motor with electronics integrated into the actuator unit. No public manufacturer case exists for C05DB; C05DA is the short to ground.
- What you may notice
- AWD warning, all-wheel drive disabled
- Possible binding or tyre scrub in tight turns if the clutch drags
- Likely causes
- LikelyActuator wire shorted to a supply line in the harness
- PossibleOutput transistor in the AWD module stuck on
- RareCorrosion bridging pins in the actuator connector
- Repair
- Medium · Usually a job for a workshop.Typical cost: €80 – €1,500
