Circuit Description
The stoplamp switch indicates the brake pedal status. The normally-closed stoplamp switch supplies a battery voltage signal to the PCM. The signal voltage circuit opens when the brakes are applied.
If the PCM detects an open stoplamp switch circuit during accelerations, then DTC P0719 sets. DTC P0719 is a type "C" DTC.
