Keyless Ignition Node (Kin)

• When the operator presses the START/STOP KIN button, the key fob is validated by the RFH. 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 ACCESSORY, RUN, and START.
• Used to broadcast the start button status

Light Emitting Diode (LED) Indicator Operation:

The LEDs in the START/STOP 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 RFH. The communication of the LED control logic from the RFH to the KIN is done over the LIN bus.

The START/STOP KIN button contain four LEDs:

• OFF Indication
• ACC Indication (Accessory)
• ON Indication (ON or RUN)
• Ignition Switch Indicator (button backlight)

The LEDs indicate the vehicle ignition position and as such are driven by the CAN-C signals related to the ignition position.

The RFH 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 RFH.
