Internal Control Module Clutch Pedal Performance
The internal clutch pedal interpretation logic in the control module does not match the external clutch switch state. Manual transmission start interlock or stop-start enable can misbehave.
Affected components
- Control module
- Clutch switch
Common causes
- Medium likelihood: External clutch switch drift
- Medium likelihood: Signal corruption between switch and ECU
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
- The malfunction indicator lamp may illuminate
