Module, Keyless Ignition Node (Kin): Operation

WARNING: This page is about a different car, the 2017 Dodge Charger. However, it is still accessible from the selected car via links, so may be relevant.

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 GO-Button the FOBIK is interrogated wirelessly. If the FOBIK is recognized as belonging to the vehicle and in the vehicle interior the system allows the ignition state of the vehicle to be manipulated by the operator between the LOCK, ACCESSORY, RUN, and START ignition 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 Go-Button on the KIN is pressed, the Radio Frequency Hub Module (RFHM) is signalled with "request to start".
The RFHM then uses the LF (low frequency) antennas to communicate with the FOB and confirm the FOB is located inside the vehicle.
Once located, the FOB's response is evaluated by the RFHM to determine if the person pushing on the Go-Button is in fact the owner. This process completes 'FOB authentication'.
Once successfully completed, the RFHM next sends the BCM the ignition switch position, which equates to a 'request to start' command.

NOTE:

In case the ignition switch does not change with the push of a button, the RKE transmitter may have a low or dead battery. In this situation a back up method can be used to operate the ignition switch. Put the nose side (side opposite of the emergency key) of the Key Fob against the Go-Button and push to operate the ignition switch.

After putting the vehicle into park, pushing the KIN's Go-Button allows the vehicle's engine to be shut off. In an emergency, pressing the Go-Button continuously for 2 seconds or repeatedly (one hit every 30- 500ms) will cause the engine to shut off when vehicle speed is greater than 5 mph.
