Starting System

Principles of Operation - Start/Stop Switch

The starting system is electronically controlled by the Remote Function Actuator (RFA) module which acts as the PATS control function. In order to start the vehicle, the passive key must be inside the vehicle. The vehicle can be started by pressing the Start/Stop switch in combination with the brake pedal. The RFA module recognizes the correct electronically coded passive key and provides initial voltage to the starter motor relay and signals the PCM to provide a ground for the starter motor relay. The energized relay provides voltage to the starter solenoid with the ignition in the START position, thereby allowing the starter motor to activate. After the PCM One-Touch Integrated Start (OTIS) feature takes over, the RFA no longer provides voltage to the starter motor relay.
