Start/Stop Button

Each time the START/STOP button is pressed, a signal is transmitted from the Wireless Ignition Node (WIN) over the Controlled Area Network (CAN) data bus to the Passive Entry Module (PEM), where the signal is then wirelessly transmitted to the FOB with Integrated Key (FOBIK). The signal is then sent back through the PEM over the CAN data bus and back to the WIN for authentication and location. After a valid FOBIK is detected inside the vehicle the ignition state can be changed.

The ignition system for the Keyless Go (KG) feature has three states, similar to a conventional ignition system. These ignition states are OFF, ACCESSORY, and ON. With the brake pedal not pressed, each time the START/STOP button is pressed and released the ignition state changes to the next ignition state as follows; from OFF to ACCESSORY, from ACCESSORY to ON, and from ON back to OFF.

To start the engine, the transmission must be in park or neutral. From any ignition state, press the brake pedal and press and release the START/STOP button. The starter will crank until the engine starts. If the engine fails to start, the starter will be disengaged automatically in 10 seconds. Pressing and releasing the START/STOP button again before the engine starts will stop the engine from cranking.

To shut off the engine while the transmission is in PARK press and release the START/STOP button and the engine shuts off. To shut off the engine while the transmission is out of PARK you must press and hold the START STOP button. The ignition state will be changed to the ACCESSORY state if the transmission is not in PARK and to the OFF state if the transmission is in PARK motion.
