Most newer vehicles have replaced the traditional key-style ignition switch with a Start Engine Push button system. A Smart Fob sends a coded security signal to the Powertrain Control Module (PCM) via the vehicle's keyless entry system when the fob is inside the vehicle. This tells the PCM that the engine can be started at any time.
Before the engine will start, the transmission must be in Park or Neutral, and the driver must depress and hold the brake pedal. Pressing the Start Engine Button sends a command to the PCM. The PCM then checks the status of the Park/Neutral Safety switch and the Brake Pedal Switch. If the transmission is in Park or Neutral, and the brake is on, the PCM then sends a start command to the starter motor to crank the engine.
