HFL (Bluetooth) module location and replacement
Hello all -
Have an '06 TSX and the hands-free stopped working. Dealer wants $1K to fix it so I was going to replace the stereo. However, this weekend the battery died out of the blue after not driving for a couple days.
Some looking around on here got me to realize it is likely the HFL module that has an open circuit and is the drain on the battery. Couple questions....
1) Where is the module? Haven't seen anything about the location on the TSX but it is in the overhead console on the TL. Took out the two screws under the sunglasses storage area but I am guessing there is more too it for removing the unit.
2) Where can I purchase a new module? Looked around at the sites shown for the TL and didn't see the TSX module listed.
Thanks in advance for the help.

I'm having the same issue, I can't seem to find out where exactly the module is located, does anybody have a diagram or pic that may help?

I'll 2nd that. That's exactly where it's located on a 06. I had read other posts about being located in the roof console but it's not. Maybe a 10 min swap. I pulled the cover underneath the glove box to give me more room to get to the top bolt.

I just bought an '06 w/ nav a few days ago and came to the conclusion after running the diagnostic check and seeing the HFL fail that mine was bad. The previous owner had commented about the battery dying recently as well and it had a brand new battery.
It would appear I was wrong however.
In the interest of giving some hope to someone reading this who may be going thru the same frustrations, I found the HFL unit (in the location shown above, ty) and did the following:
1. unplugged that main connector (green)
2. took off the cover to the unit
3. pulled out the small circuit board on top that plugs in to the main module (white connector).
4. blew on them like it was a nintendo cartridge.
5. put them back together and did a new diagnostic check.
6. Everything now passed!
So hope that helps someone somewhere.

06 TSX- HFL disconnect
Hey guys, I been reading the posts, and ive been having similar issues, am I correct that after i unplug the green plug from that bluetooth box that- that is all I have to do to disconnect the bluetooth so it wont drain my battery anymore?
I brought a new batter in Aug, and since then I have had to have a jump start 3 times. I had the system tested and it came back that the battery is fine, and the alternator is fine, so i was wondering if this system was draining the battery after i read the posts, (back story .... my HFL stopped in june, but i didnt think anything of it.)
Thank you for any help you can provide.

So, I confirmed that my dying batteries (3 in 7 years) were probably due to the HFL pulling almost 200 mA when the car was off (car does sit for 2 weeks at a times sometimes) - I unplugged it for now. Does the procedure outlined above fix the battery drain issue or is it just normal for the unit to draw that much?

Failing HFL will draw power. Disconnect and fix/ buy a new one or leave it disconnected

A quick thanks to the posters in this thread. Purchased the HFL part through a salvage yard for about $100. 20 minute install and I didn't drop the glove box cover. That's what makes these forums great. Thanks!

Under glove box cover removal
I have a similar dying-HFL module issue. Pulled off the footwell cover, did an unplug then replug. Worked briefly, then stopped again. Next up are the blow on circuit board, then remelt solder in oven tricks. However they require removal of the module.
Can someone provide a detailed description (with pictures would be better) on how to remove the cover underneath the glove box? Seems like that is needed to get to the upper bolt(s) of the HFL. I'm not sure if I ask my Acura dealer to do that during my next service visit, if will
Thanks.

I know it's an old bump, but I'm troubleshooting the HFL/BT functionality as well. If you have navi, you can press the following keys to get to a service menu: map/guide + menu + cancel and the system screen will come up. On the service menu, press Navi System (or something like that) to get a component diagram, which should show all green modules navi, radio, hfl, etc).
My question is are the HFL and Bluetooth functions two separate components/modules? Meaning, if the voice commands work for navi and A/C etc, but the Bluetooth connectivity (pairing timeout) doesn't work, is it a Bluetooth module issue? Or are the BT and HFL the same module, and the BT components inside faulty? BTW I have no battery drain that I can tell.
Thanks.

+1 on the wizardry.
My HFL has not paired for years and on a whim I researched it today.
I was not able to remove the unit completely as the top 10mm bolt was hard to access, but I was able to remove the bottom green connector and spray the unit with compressed air. Plugged it together and now it paired right away. Thanks!
