Engine Disconnect Clutch Actuator Control Circuit Driver Current/Temperature Too High
The output driver for the engine disconnect clutch actuator reports current or junction temperature above its protection threshold. Sustained high load on the actuator or short-circuit fault.
Affected components
- Engine disconnect clutch actuator
- Hybrid control module
Common causes
- High likelihood: Short to ground in actuator wiring
- Medium likelihood: Actuator mechanically jammed — high stall current
Possible symptoms
- Check engine or transmission warning light on
- Harsh, delayed, or missing shifts
- Possible limp mode (locked in one gear)
- Slipping or shuddering during gear changes
Diagnostic notes
