Bluetooth HFL module location
I'm having trouble with my Bluetooth HFL draining my battery after a few days parked. I just recently changed my battery and it seems to have drained that already. Does anyone know where the bluetooth HFL is located for an 2012 Acura TSX?

It's definitely an issue on the 3rd Gen TL's not so sure about the TSX though.
Have you don ea parasitic draw test to determine where it is before randomly pulling things?
Does your HFL work?

it's the panel right above your feet on the passenger side.. It's directly attached to it. You can leave it disconnected if you would like to test for parasitic draw.
I permanently disconnected mine after I put in a aftermarket stereo with steering wheel controls (including call and hangup functionality).

did disconnecting the blue tooth module fix your problem? I'm having same issue with my 2011 tsx? Where is the module located?

did you get your issue fixed?
it seems like i am having the same drained battery on my 2011 tsx. i've had to swap out new battery very often, ranging from a few months to 1 year.
is the HFL only for bluetooth connection? What features am i missing with the disconnection?

No, never got issue resolved... still trying to figure out what is draining the battery... I live in the North East so to cold to try to troubleshoot the issue now. I plan on putting a multimeter on the the battery to figure out what fuse is drawing down on the battery... once I get that... I’ll need to figure out what
is on that circuit and troubleshooting from there will be the real challenge.... might be over my head at that point.
I had a mechanic say he disconnected the HFL module but saw no difference in the draw of the battery.... I don’t believe he did that so in the spring I’m going to disconnect it myself to see for the heck of it if it makes a difference.... although I have not gotten to it, I’ve been told the location is on passenger side near the kick panel...
for now I installed a battery monitor which sends alerts to my iPhone, I can watch the current voltage and it graphs out the voltage over a 24hr period... it’s pretty nice, cost me 39 bucks on eBay.... once I see the voltage drop below a certain threshold I start the car and let it run for 20mins to recharge it so it’s not dead after two days of non driving...
hopefully in the spring I can figure out what’s going on because as I’m sure you know, this is frustrating as hell.
if you figure it out please post the fix.

I know you posted the location of the HFL quite a while back but ... IM HAVING THE SAME BATTERY DRAIN pRoblem ON MY 2011 tsx w/nav... you said the HFL is located above your feet on the passenger side....is this the location for 2nd gen TSXs (2011).... do I have to remove the passenger side dashboard cover.... that’s where the blue light is... if yes, do you know how that comes out? Is it just clips or do I need to take out screws? I’m having a heck of a time finding this thing.

In image HFL 2 it mentions how to remove the passenger's dashboard undercover on page 20-184, so that would be really useful as I think I have an HFL problem so need to remove it.
But would be great to get hold of the manuals themselves if you know the source?
