Contact Breaker At Clutch Pedal/Stop Lamp Switch
The brake or clutch pedal must be depressed for the vehicle to start.
The clutch pedal contact breaker is only installed on vehicles with a manual gearbox and is installed with the clutch pedal.
The contact breaker is in its open position but closes when the clutch pedal is depressed more than 90% of its stroke. The Engine control module (ECM) and Central electronic module (CEM) check that the contact breaker is closed when a so-called passive start is initiated.
If the vehicle has an automatic transmission, the signal from the stop lamp switch is transmitted to the Engine control module (ECM) and Central electronic module (CEM).
The stop lamp switch is installed together with the brake pedal. The contact breaker is in its open position but closes when the brake pedal is depressed.
