These are not really valid terms. Do they mean the Crank Shaft Sensor or Interruptor? What was the code number and what is your car doing improperly?
no they mean the Switch Commutateur Interruptor which is the brake light switch located above the brake pedal if you follow the pedal upwards, you will see it but my question is how do I remove the old one to install the new one?
