OSS (One-Touch Start System)
With the one-touch start system, when the engine switch mounted inside the vehicle is operated, OSS-ECU receives the stoplight switch input signal from the brake pedal, the P range detection switch input signal from the selector lever assembly, and performs the certification communication with keyless operation key using KOS-ECU, the certification communication with electric steering lock, and the engine start certification communication with ECM. Only when the input signals and certification communications are valid, the one-touch start system performs the power supply changeover control, the electric steering lock locking/unlocking control, and the engine start control.
