Acura TL Bluetooth/HandsFree Link Problems

18911131416

Comments

  • My 2006 Acura Tl bluetooth also stopped working. I researched and after hours and hours of research, I got the answer. Oemacuraparts has the bluetooth module for $185 including shipping and tax--its under the interior lighting section--TELEPHONE ASSY., HANDS FREE *NH528L* (MOON LAKE GRAY)--they also have the two other colors. They shipped me the part in 3 days---its the exact part and color of my current overhead console. I looked up service bulletin 05-020 and this tells you exactly how to take this apart--very, very easy. I took it apart ahead of time to know what I was doing and it took me 8 minutes to replace this and put back once it came in. I also have navigation and did not replace any delay part that is mentioned in the service bulletin. Once I replaced this part, the bluetooth worked correctly immediately. You do have to reprogram it and store all your numbers again, but this was by far the cheapest and easiest fix out there.

    Thx for the posting! I just redid mine and like you said by far the cheapest way to go... I also emailed the Cerritos Acura Dealer about this and they have agreed to refund my 115$ diagnostic fee (Credit I should on next service). The person I talked to stated that Acura has lowered the cost of the HFL unit since (THEY KNOW ITS AN ISSUE ON THE TL and MDX) that is why the cost is now 177$. I somewhat believe this and somewhat think they are full of it! I say that because i dont believe the unit used to cost 600$ which is what I was also told. I think this unit was maybe 300$ or so at one time. anyways thx! and if anyone happens to have an issue like this and the dealer quotes you anything above 300$ message me and I will send you the email I received.
  • Turie, I attempted to message you but there didn't seem to be a way to send a message just you.

    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!

    Ok 1st here is where you can buy the part at-

    http://www.oemacuraparts.com/index.php?p=page&page_id=part_picker&make=Acura&mod- - el=TL&year=2005&version=4DR+BASE&transmission=KA5AT&system=PARTS&component=INTER- - IOR+LIGHT

    8 39770-SEP-A02ZB TELEPHONE ASSY., HANDS FREE *YR167L* (LIGHT TAN) $181.17 $173.93 1 Add to Cart Add to Cart
    8 39770-SEP-A02ZC TELEPHONE ASSY., HANDS FREE *YR240L* (LIGHT CREAM IVORY) $203.70 $195.55 1 Add to Cart Add to Cart
    8 39770-SEP-A02ZA TELEPHONE ASSY., HANDS FREE *NH528L* (MOON LAKE GRAY) $181.17 $173.93 1 Add to Cart Add to Car

    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?
  • Nope, I did not pay the Stealership anything. Thanks again!

    I brought my 2006 TL for A service on Saturday and to see why my HFL wasn't working. I was told it is not covered by warranty (I purchased the 100,000 extended warranty). I asked them how would I be able to break it and they said I can't, so I asked why isn't it covered by the extended warranty? They said the wording is in the small print of the extended warranty contract.

    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.

  • Just so you know--I purchased a CPO 2005 Acura TL 3 yrs ago and also have the extended 100,000 mile warranty. The HFL failed about a year and a half ago. I called the dealer where I purchased it, brought it in and said I was not paying for it because it should be covered and they did not charge me. The dealer told me normally without the Warranty I would be out 600+ dollars. Not sure if it being a Certified Pre-Owned has anything to do with it but I would go back to your dealer again and complain. My dealer also put 1 odd ball tire on my car too when I purchased it--which my mechanic spotted during my 1st oil change and tire rotation--I made them replace my tire too--and made them match it to my existing brand--again--no out of pocket from me. You have to be tough with these guys or they take advantage of you. Its not like this is a "throw away" car like some econ car..These are higher end cars and I expect the dealer to treat me and my $$ with respect. Good luck ;)

    I have a 2007 MDX and my handsfree button just stopped working completely, the car does not recognize my phone at all, in fact nothing happens whatsoever when the HF button is pushed. I was quoted over $500 to fix it. If there is a way for me to get the email you reference I would love to have it.

    Thanks for your reply!

    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.

    Hi there if it was you who tried to Instant Message me go ahead and send me your email address.

    Thx

  • My 2005 Acura TL would not start this morning. I replaced the battery in July. When trying to start the car, I had lights but the battery would not turn over the motor. After jumping the battery, the car started. Reading all of these blogs I suspect an HFL issue. My HFL stopped working in April and I did not think about having it fixed. After reading these blogs, it makes sense. Also, I noticed that there is something in the electrical system that is drawing energy from the battery while the car is not on. The Acura Stealership wants $120 an hour to diagnose an electrical problem and say it will take 2-3 hours to diagnose. I have read the blogs and found the Service bulletin as well as replacement 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've had no problems with the HFL, until recently... Took it to my regular service guy, after my battery would drain when sitting for a very short period of time. Battery is brand new, and the charging system is working properly. There is, however, between a 2.5 and 5 amp draw on the battery when it sits. They've tracked it back to what they think is the HFL.

    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.

  • I would suggest using service bulletin 05-020 and follow the directions of prying the tab of the overhead lighting console, pulling down, taking out the 4 bolts, and disconnecting the bluetooth module. This takes about 10-15 minutes and is very simple to just unplug it.. I never work on cars and this was very simple for me. I changed out my module and it works better than the original--so I guess it may have never worked 100 percent correctly. I think if you try taking out the fuse you may lose other items connected on that fuse. Only 10 minutes to disconnect the module and you will know for sure.
  • Add me to the list! My HFL died last week! When I bought the car, it was one of the reasons that persuaded me to pick the car! Very disappointed that it costs so much to replace the unit! Not a very happy camper here! And to think, I am deciding what new car to buy right now....this latest example has me looking elsewhere! Acura used to be such a great car!
  • Thanks to all of you digging deep on this! Will order part and put it in myself! Again, thanks!
  • Wow! What's with everyone's bluetooth failing at the same time? My 2006 TL HFL started acting up last week. Button doesn't do anything, or sometimes work (usually not). Got it to pair today but it dropped in the middle of a call.
  • I have the same issue described with my 2006 Acura TL. I am planning on using bulletin 05-020 to replace the HFL unit myself. This would be my first foray into messing with electronic components in a car. Am I correct in assuming I should disconnect the car's battery before opening up the roof console and replacing the HFL? Or is that overkill for this type of project?
  • No reason to disconnect the battery. Overkill yes. You will need a set of feeler gauges--at Lowes for $6 or $7---to take down the overhead light console without causing any damage. Real simple......
  • Hello all - just want to report one last thing before you give in or either replace the HFL...

    **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!
