Functional Description - Keyless Ignition Node
When the operator presses the KIN button, the wireless FOBIK is validated by the RF Hub. If the key fob is recognized as belonging to the vehicle and is inside the vehicle, the system allows the ignition state of the vehicle to be changed by the operator between the ACC, RUN, and START ignition states. The KIN is also used to broadcast the start button status.
Light Emitting Diode (LED) Indicator Operation: The LEDs in the KIN button provide visual indication of the ignition system and button use to aid the driver. The Logic for LED control is implemented in the RF Hub. The KIN button contains four LEDs:
- OFF Indication
- ACC Indication (Accessory)
- ON Indication (ON or RUN)
- KIN switch indicator (button backlight)
The RF Hub will log a Diagnostic Trouble Code (DTC) indicating an incorrect ignition status value is present; in this state, the ignition status is unknown. This will continue until the correct signal is received by the RF Hub.
