Acura Repair Questions? Ask a Mechanic for Answers ASAP
These can be a problem to reset. What happens when you press the talk button? Does it ask for the code or is it not responding at all.
That's what I was afraid of . Unfortunately on this model you need the factory scan tool and another car, Please remember I didnt design the system . Here is the instruction from Acura.
Is there an owner of a vehicle who’s lost or forgotten his or her HandsFreeLink (HFL) passcode? You need to clear the old passcode with the HDS before he or she can add a new one. There’s just one small hitch, though: 2005 MDXs can’t talk with the HFL; they don’t have B-CAN. To get the job done, you’ve got to pull the HFL unit out of your client’s vehicle, remove the HFL unit from an 2005–06 RL, 2004–06 TL, or 2006 TSX, and install your client’s unit. Once you’ve done that, connect the HDS to the 16P data link connector (DLC). From the System Selection Menu, select Body Electrical, Hands Free Link, Inspection, and then Passcode Clear. Follow the prompts. The HDS clears only the passcode. All phone entries and paired phones stay in the system. When you’re done, disconnect the HDS and reinstall the HFL units.
