Push Button Start System: On
The RFA module or the BCM must recognize a programmed key before the ignition state changes out of OFF. When the START/STOP button is pressed with the ignition off, the RFA module (and if no key is detected the BCM) checks for a programmed key as part of the PATS function. If no programmed key is detected, the ignition remains off. For detailed PATS information, REFER to: Passive Anti-Theft System (PATS) - System Operation and Component Description
When the ignition is in the ON mode, the BCM activates the accessory delay and ignition relays (by providing ground to the coil side of the relays), and sends a message over the CAN to other vehicle modules.
When the vehicle enters ON mode, multiple indicators in the IPC prove out and the IPC displays the gear selection and the vehicle mileage.
