1. Make sure the cell phone is approved by checking www.acura.com/handsfreelink, or call the HFL call center at 888-528-7876.
Is the Bluetooth cell phone approved?
YES -
Go to step 2.
NO -
Explain to the client that the cell phone is not approved. Recommend they get a cell phone that does appear on the www.acura.com/handsfreelink website.
2. Check if the cell phone has any special requirements (software version, configuration, etc.). Call the HFL call center at 888-528-7876 for help.
Is the correct software version loaded and is the cell phone properly configured?
YES -
Go to step 3.
NO -
Explain to your client that the cell phone software needs to be updated or the cell phone needs to be configured properly. If the HFL call center is able to help you configure the cell phone, explain the proper settings, otherwise direct your client to contact their cell phone manufacturer or carrier.
3. Check the features of the approved cell phone at www.acura.com/handsfreelink, or call the HFL call center at 888-528-7876.
Are all the features approved?
YES -
Go to step 4.
NO -
Check and see if the feature that is not approved is the same as the client complaint. If the complaint is about the feature that is not approved, the vehicle is OK. Explain to the client that the feature is not approved to work with the HFL. If the complaint is an approved feature, go to step 4.
4. Turn the ignition switch to ON (II).
5. Press and hold the HANG-UP button or the HFL BACK button for more than 5 seconds.
Do you hear, "The hands free system is OK"?

Go to step 6.

Check for HFL DTCs with the HDS.
6. Try to duplicate the problem or have the client demonstrate the problem.
Can you duplicate the problem?
YES -
Go to step 7.
NO -
The system is OK at this time.
7. Pair the cell phone to a known-good vehicle (same model, year, and trim), and try duplicate the problem.
Does the cell phone have the same problem on the known-good vehicle?
YES -
Call the HFL call center at 888-528-7876 to make sure the cell phone is configured correctly and has the correct software. If the cell phone is configured correctly, it is either a characteristic of the HFL system, or a characteristic of the particular approved cell phone being used. Explain to your client that this is a system characteristic. Another cell phone from the approved cell phone list may give more favorable results.
NO -
