From what I have read it only disables the system temporarily until the key is cycled again and it not a permanent fix. Can anyone else confirm this? I also read that ANC is disabled anytime a door is opened, which may prove useful in testing.is it permanently off ??
No, it is not permanent for 8th or 9th gens. Once you turn off your key, wash rinse repeat. Or, unplug the ANC harness from behind the radio to make permanent...anyone to confirm if this is a permanent solution?? I have an 8th gen accord with free hands and I would like to keep it working =D
Yes, unplugging the connector I showed will disconnect both microphones and disable ANC while retaining HFL.I haven't done it yet,but there are 2 mics in the car,the rear can be unplugged..
The front is different...im going to pull the mic up by the map lights and cut the white wire...
Cuts the anc mic and keeps the hands free.
This is exactly what I posted about here: Disabling Active Noise Cancellation (ANC) in 8 Gen (2010) AccordHello!
This is my first post here, so figured I'd make it something useful. I was installing an amp/sub in my 2008 EX-L V6 and I read numerous threads about disconnecting the mics and all that other stuff, but when doing a Google search of ANC I came across this video. Figured that since this worked in an Acura I gave it a try, and it worked! The stock system is SOOOO much cleaner now as well.
I haven't seen any other posts regarding this solution, so here you go- (EDIT- one note, the Accord doesn't stay "ANC", it has the code 6P11 or something like that, but it is the same)
buuuut: disconnecting that connector 'C' looks like it also disable the input for the SVC(speed ssensitive volume) user control item.Forgive me if this has been posted already,
This is something I discovered after installing an amplifier and component speakers in my front doors. I would notice that at low engine RPM's my speakers would make a "wahhh" sound and I could feel the speakers pulsing. I thought it had something to do with my amp until out of curiosity I performed the ANC diagnostic test which temporarily disables the ANC after the test is performed. I should mention at this point that I disconnected the ANC microphones a long time ago. After performing the test I noticed that the "wahh" and speaker pulsing would disappear until I restarted the engine. Luckily I have a copy of the service manual which revealed:
This led me to conclude that even with the ANC mics disconnected, the audio system will still produced sound cancelling noise based on engine speed
I decided to disconnect the connector responsible for sending ANC microphone and engine speed signals to the factory radio which ended up fixing my problem.
Here's the factory radio removal tutorial.
Now I can enjoy my stereo system noise free! Hope this helps people trying to install aftermarket audio equipment while keeping the factory radio.
Note: I have the 6-cd non-premium audio system without navigation but the connector seems to be the same one on all systems. Also an alternative way of disabling ANC is by tricking it into thinking that one of the doors is open all of the time but I haven't figured out which wire you have to disconnect to do this. Disconnecting the ANC connector is easy enough anyways.
I have the 2008-10 Honda Accd Service Manual downloaded, and nowhere within it is this module mentioned or illustrated.After some serious online research, I have found the following:
1. What is being referred to Active Noise Cancellation (ANC) is
"actually" called an ACM Unit by Honda (see link below).
2. This ACM unit appears to be independent from the radio unit,
based on the images of the ACM units for sale online (again, see
2009 Honda Accord Acm Unit Active Noise Control 38700-TA0-A01
For those who want to know "what" this unit looks like, the images
should help identify it when searching to unplug it.
