I have been having problems with my HFL for a couple months and have just been making due without it. However now, my battery keeps dying because apparently the HFL is draining it.
I took the car into my local Acura Dealer (Acura of Pleasanton, CA) and they want $150 just to diagnose it and another $500 if it needs replacement. Could you send me whatever information you were able to gather? Also did you just replace the module yourself or did you have the Dealership take care of it for you?
Thanks for the help!

One of those should be the color you need, also it literally takes about 10 minutes to do this yourself- locate the Acura Service Bulletin 05-020 (Google it) and it gives you the directions to fix it.
think this is the link- www.acuraworld.com/tsb/3gTL/b05-020.pdf
Any other questions let me know.
O.o you didn't pay the Stearlership anything right?
After reviewing all these complaints, It is an Acura service issue not an owner issue. I am on my 4th Acura and told the service rep, to discuss my issue with the Service and Sales Manager and call me back with a better resolution. I'll let you know what the response is later.

I took my 2006 Acura TL for maintenace service on 10/22 and to my amazement they took care of my HFL without much hassle. I did agree to pay $50, since some of the other messages commented that they agreed to pay a minimal amount to ensure they have a warranty on the newly installed HFL.

Big Question??? Will the car continue to work and stop drawing from the battery if I remove the HFL and NOT replace it with anything? I do not need the Bluetooth feature and I would like to save the $180. But only if this will solve the problem and not cause any future problems.
If you have suggestions, I would really appreciate it!
I can't find a fuse/circuit diagram anywhere to make sure, but he noted it was a 40 amp fuse (#15) under the hood, and fuse #6 from inside the cabin.
I've called Acura, and of course they want to run a $125 per hour diagnostic to likely tell me the same thing.
The Service Manager at Acura told me this is a known issue, and will likely result in either needing to disable or replace the HFL module...cost of $750.
In some other threads on this forum, I have seen the replacement part, and TSB 05-020, where it actually appears to only cost $180 for the part, and the billable hours for the change is .3 hours.
I'm hoping someone else has a little background in this, or maybe knows where I can find a circuit map to do some of my own verfication.

**Let me preface this with my HFL was still "working" it just would not recognize or sync with and phones**
I was about to replace mine when i decided to try the old one again just for Sh!ts and giggles... lo and behold i realized that the HFL is actually 2 pieces that connect at a relitively thin connector. since there didnt seem to be a solid connection. when i pressed them back together and tried to reconnect the phone - VIOLA! - came right back on! i just used some electrical tape to wrap around the two pieces (keep in mind not to cover any of the slots or holes for mounting).
**Also i need to mention i did this with the car still ON. ive read alot about how the bluetooth module gets stuck while "booting up" and never finishes..
but perhaps, like pcs sometimes do, it doesnt shut down properly leaving it kind of in limbo.**
so...
1. make sure car is running
2. dismount and disconnect bluetooth
3. check that connection is secure between two boards (electrical tape)
4. with car still running, reconnect power wires
5. test bluetooth with phone - first make sure connects and makes calls, then move on to making sure it reconnects after car is shut off and then back on
Disconnected the battery for about 15 min and tried again - still worked
Restarted car multiple time - still worked
Shut off bluetooth on phone, and turned back on - still worked
If all those pass then you may have just averted at minimum a $200 mini-crisis.
Good luck!

Also, shop around a bit for the HFL unit itself. I was able to find it cheaper by ordering directly through the parts department of my local dealer. It was about $30 less than ordering from several of the OEM acura parts online stores.
This is my post at #207 and if you google the service bulletin you will step by step instructions... You can get feeler guages that worked great at Lowes for about $7 and it will prevent you from doing any damage to the overhead light console. Super, Super easy and anyone can do it as I am not very mechanical at all.
Have a trip this Saturday and the battery is dead after one day not driving. So worried! Thanks a ton for any help!
If it's draining, and you disconnect it, leave the care the normal amount of time that is has been taking to drain, and if it works, I think you've found your problem.
I went through this on my '05. It turned out to not be the HFL, but the door lock actuator and the window switch. Those draws come from the same area, and it takes some time to figure out the exact details.
Thanks for the expertise!
p.s.- Great car overall- way too complicated, but needed to switch out my 2000 TL wi. just under 200k.
1st problem is the FOUR DIGIT CODE.
I don't know the previous owners code, so I'm stuck
Any advice?
Thanks in advance
Unfortunately, the sticker on the glovebox was MIA.
Tomorrow, I 'll follow your advice and get the sequence of command from the dealer to resolve the problem.
I'll keep you posted.
Thanks again

So far, this "cleared the system & password lock
1) Press & release the "talk" button & say "System"
(the response should be "This process will clear all phones... is this what you want?"
2) Press & release & say "YES"
( the response will be "Preparing to clear.....")
This will take about 2 minutes
3) After the process, say "OK"
The response will be "System cleared"
'hope this helps
(still haven't paired" phone, but working on it)
I shut down the MDX, immediately restart the car....and the problem goes away!
Any ideas as to what the problem is?
Thanks in advance for your help
Let me know if you find a solution and I will do the same.
Tried pulling fuses, but no luck.
We decided to try the "take it all apart and put it back together" route before purchasing the OEM part. Thanks to this forum we followed the bulletin- it was super easy to do (25 min total and we have zero clue on car repairs).
We even took the power cord off the actual hfl unit (in case there was a loose wire) and opened the hfl unit (likely unnecessary, but in case a capacitor or something was obviously loose-- I don't think anyone needs to do this).
Then put everything back together. Hfl worked AND remembered the phone!! Even the garage door pairing was remembered (thought we'd lose that when we pulled fuses).
Anyway, wanted to post to give another alternative to replacing the unit.

(great instructions, but we had English hex screws not Metric ones- I didn't note the size)
Best of luck.
The dealer wants $400. The price seems high for a simple replacement
If I were to by a new unit, is a simple plug installation all that is needed, aside from set up.
Thanks in advance for all help.
Acura of Perioa is where I bought mine for my 2005 TL and it was only about 150$ i believe.
you might want to try them.
was mine for an 05 TL but i highly doubt its any diff for an 07- you of course need to choose the color.

Thanks! But is this the whole moon roof assy? Shouldn't there be a p/n just for the small "black box" HFL?
Sorry, this may be a dumb q, but I'm not following why I need to match my interior color. I was able to disassemble everything using the service bulletin, and got to this 5"x2" HFL box. Isn't that all I'd have to replace? Or am I actually replacing the trim?
Sincerest Thanks,
Roh
