Module, Keyless Ignition Node (Kin): Operation
The Keyless Go system with the Keyless Ignition Node (KIN) replaces the conventional key and ignition switch with a momentary button press and a wireless electronic key (FOBIK). When the operator presses the Start/Stop Button the RFH wirelessly interrogates the FOBIK. If the FOBIK is recognized by the RFH, the system allows the ignition state of the KIN to be manipulated by the operator between LOCK, ACCESSORY and RUN states. This causes changes in the ignition status signals on the vehicle's CAN-C data buses and hardwired outputs controlled by the starting system master. As far as the vehicle's ignition system is concerned, keyless go control is indiscernible from legacy conventional control using a rotational switch and key.
- When the KIN button is pressed and the brake pedal depressed, the Radio Frequency Hub (RFH) is signalled with "request to start".
- The RFH then uses the LF (low frequency) antennas to communicate with the FOBIK and confirm the FOBIK is located inside the vehicle through the use of RF antennae placed strategically in the vehicle.
- Once the FOBIK is validated by the RFH it completes 'FOBIK authentication'.
- Once successfully authenticated, the RFH sends the ignition switch position to the BCM. The BCM then carries out the requested command.
In the event that the FOBIK is inoperative due to a low battery, a back up method can be used to operate the ignition switch. A low voltage signal is sent through the KIN's internal antenna that activates the chip internal to the key. Place the nose side (side opposite of the emergency key) of the Key Fob against the Start/Stop Button and push to operate the ignition switch.
Once the vehicle is in PARK, pushing the KIN's Start/Stop Button will engine to be shut off. In the case of an emergency, pressing the Start/Stop Button continuously for 2 seconds or repeatedly (one hit every 30- 500ms) will cause the engine to shut off with vehicle speed greater than 5 mph.
