Theory Of Operation

The Radio Frequency (RF) Hub module sends out a start signal request message over the communication network when either a valid remote start request occurs or the Keyless Ignition Node (KIN) receiver Start/Stop Button is pressed to the Start position, with the Brake Pedal applied and the FOB is present in the vehicle. The Body Control Module (BCM) receives the start signal request message and provides voltage to the coil of the Starter Relay.
