Active Noise Cancellation Operation

The main components of the Active Noise Cancellation system are:

• 3 microphones in the vehicle headliner: one above each front seating position, and another above the right side of the second row seat.
• A discrete engine speed (RPM) signal from the engine control module to the amplifier
• Active Noise Cancellation electronics and software integrated into the audio amplifier
• the vehicle speaker system, connected to the amplifier, to output the desired cancellation frequencies

The Active Noise Cancellation system is operational under the following conditions:

• The amplifier has passed all self diagnostic checks
• All doors/liftgate are closed
• Battery voltage is between 9.5 V and 16 V
• The vehicle cabin temperature is less than 140°F (60°C)
• Engine speed is between 550 and 3000 RPM
