Active Noise Control (Fake Engine) Disable How-To
We all know I like to tinker and pull wires...or if you don't, now you do. lol
I did a little reading of the diagrams for the DSP (Amplifier) and found the inputs for the Active Noise Control (ANC) inputs on the factory amp. This is only for the vehicles with Sony audio. I can't speak for any of the others, because I don't have anything else to experiment with. So here we go. Try at your own risk. I'm not responsible if you blow anything up!
A little bit of education, the Audio Control Module (ACM) is behind the dash. It is what takes the audio from the FM/AM/Sirius/SYNC/Door Chimes/ANC and sends it to the DSP in the rear of the truck on Sony models. Mine is the Lariat with Sony and 3.5L eco.
On the amp, behind the rear seat, connector 3154A (bottom connector when looking at the front of the amp:
Pins 10/20 Right Front ANC In
Pins 8/18 Left Front ANC In
I used my pin pulling tool and removed those pins and tested it by hooking it to a set of headphones. Started the truck, closed the doors, Sure as sh*t, there was the engine sound. With those wires removed, there is no sound routed into the factory amp and out to the speakers. Added bonus, that hiss that people get with after market amps is gone!
Hooked up to headphones to test.
Here's what I did to protect the wires after I was done testing.
Shrink wrapped one connector, then shrink wrapped the other on top of it.
I did the exact same thing with the other pair.
A bit out of order, but this is the end of the connector that needs removed in order to start pulling pins.
After doing this mod, I had no more fake engine sound. I haven't taken it out on the highway yet, but I can tell right away that the engine sounds are missing. There is no difference to the audio output for music. Everything else works as it should. As a warning, just so that anyone who tries this doesn't think they broke something, when that plug on DSP is disconnected, and reconnected, the door chimes will may not play through the speakers for several minutes until the computer realizes that it has been reconnected. Not a big deal, just something to be aware of.
