REMOTE RADIO SWITCH WITH PADDLE SHIFT

REMOTE RADIO SWITCHES

The six switches (back of steering wheel spokes) in the two remote radio switch units are normally open, resistor multiplexed momentary switches that are hard wired to the right steering wheel switch (speed control switch). The right steering wheel switch (speed control switch) provides a five volt signal and return circuit to the switches. Both switches share the signal and return circuits. The right steering wheel switch (speed control switch) senses the status of the switches by reading the voltage drop of the signal circuit.

When the right steering wheel switch (speed control switch) senses an input (voltage drop) from any one of the remote radio switches, it communicates the switch status message to the Steering Column Control Module (SCCM) via the LIN Bus (through the clockspring). The SCCM then broadcasts switch status information over the CAN Bus to the audio system. The electronic circuitry within the audio system is programmed to respond to these remote radio switch status messages by adjusting the audio settings as requested.

The SCCM then broadcasts switch status information over the CAN Bus to the transmission control module (TCM) communicating driver request for transmission upshift or downshift.
