HFL issue

[243476dDUDE]

Tim, I need your expertise.

I noticed my Treo 700wx no longer works with my '06 TL soon after my car was serviced. Apparently the battery failed a load test and the dealer replaced it. I've used the HFL w/o issue with this Treo and an older Motorola until my recent service. Of course the service agent was able to get the phone to connect, but after I drove off the lot it disconnected by itself, and I haven't been able to get the phone to pair since.

I've tried disconnecting the battery to reset the system, the diagnostic (Holding the BACK button), clearing the phone from the menu, as well as pulling the plug from the HFL unit itself without luck. Diagnostic says the HFL is 'OK', but I still can't pair the phone. I've tried pairing my old Motorola and it also doesn't seem to pick up the HFL signal.

I did notice that after I pulled the plug off the HFL, reconnected the battery /wires and ran the diagnostic, the message did say the HFL needed to be serviced. However, after I disconnected/reconnected the battery again, it no longer gives that message...just "HFL is OK'.

Could the diagnostic mode be faulty? Does anybody know of a way to test to see if the HFL is even transmitting a signal? I think the HFL was shorted during the service, but there's no chance of proving it Dealer did offer a 10% discount, but I'm thinking of looking for this unit in a junkyard if all else fails. Lastly, is the HFL the same for all models? ie..are these interchangeable between Acura models?

First, try visiting HandsFreeLink | Acura.com , there is a diagnostic and compatibility reference there.

Next, is Acura's HFL customer support line at (888)528-7876 for further
help. It’s open Monday thru Friday from 6:00 a.m. to 6:00 p.m. CST; Saturday from 7:00 a.m. to 6:00p.m. CST; and Sunday from 8:00 a.m. to 6:00 p.m. CST.

If both yield no results, this is Acura's initial checklist (may be redundant to what you've done, but here it is anyways)

1. Make sure that the cell phone is compatible with the HFL.

2. Make sure that Bluetooth is turned on.

3. Make sure that the cell phone’s battery is fully charged and there’s a good, strong signal.

4. Make sure that you’re using the HFL Talk and Back buttons on the steering wheel, not the navigation
buttons.

5. If you’re trying to pair a BlackBerry® or a Palm Treo™ device, make sure that you’re pressing the shift key on the device when entering the four-digit pass code. If you don’t press the shift key, you may be entering letters instead of numbers. The HFL doesn’t recognize letters.

6. If you can’t get the phone to pair with the HFL, try doing a soft reset by turning off the phone and turning it back on.

Also, check to see if the phone has an Always Ask/Trust, Authorize Device, or similar option. If so, make sure that the phone is set to Never Ask, Authorize Device, Trust, etc. (The actual setting name will depend on the cell phone maker and wireless carrier).

Hope that helps

Hi Tim,
It's taken a while to revist this issue, but I just got off the phone with the Handsfree support and they had me powercycle the phone and try to pair. Unfortuantely, they were not able to resolve the issue. Tech suggested I take the car back to dealer and advise them that HF support recommeded they take another look at the car, and possibly reset it; and might even be a loose connection. What different steps would the dealer take that hasn't been done?

I've also tried the steps you've outlined and still no luck. BTW, how do you work the HFL using the nav buttons?

Any other thoughts?

Thanks,

Unfortunately, that's where my expertise on the issue ends....from there, use their suggestion and bring it back in to the dealership. I assume that it'll be covered under warranty, if the vehicle is still in warranty.
