A fault in the clutch pedal switch "A" circuit. The module uses this switch to know when the clutch pedal is pressed - to permit starting, to cancel cruise control, and to adjust fuelling during a gear change. Vehicles often have two of these switches for redundancy, so the fault may show only as a warning rather than as a change in behaviour.
Possible causes
- CommonFailed or misadjusted clutch pedal switch "A"
- CommonWorn or broken switch striker on the pedal
- CommonWiring or connector fault in the footwell
- PossibleWorn clutch pedal bushings changing the pedal travel
- PossibleAftermarket alarm or immobiliser spliced into the circuit
What you might notice
- Engine will not start, or starts without the clutch pressed
- Cruise control will not engage
- Stop-start system disabled
- Check engine light on
What to check, in order
- Watch the switch "A" state on the live data screen while pressing the pedal fully.
- Compare it with the other clutch switch. One reading correctly and the other not immediately identifies which switch is at fault.
- Check the switch adjustment and the striker on the pedal. Adjustment is the most common fix here.
- Inspect the connector in the footwell, where feet catch it.
- Check the pedal bushings for wear, which changes how far the pedal travels.
