ICC Steering Switch
WARNING: This page is about a different car, the 2012 Infiniti M35h. However, it is still accessible from the selected car via links, so may be relevant.
The intelligent cruise control steering switch is connected in series to different resistors in each switch circuit. HPCM reads the voltage values that are sent from each switch and split by the resistors, and detects which button is operated. For the intelligent cruise control function, refer to "SYSTEM DESCRIPTION ".
