HFL System Troubleshooting
NOTE:
-
You must be able to duplicate the client's concern to successfully diagnose and the problem.
-
Always use the client's phone.
-
Make sure the phone is approved and configured correctly. Online, go to www.acura.com, or call the HFL support desk at 888-528-7876 for
further assistance.
1. Connect the HDS to the DLC.
2. Turn the ignition switch ON (II).
3. Check for DTCs.
Are any DTCs indicated?
YES - Repair the indicated DTCs and recheck.
NO - Go to step 4.
4. Try to duplicate the problem.
Can you duplicate the problem?
YES - Go to step 5.
NO - The system is OK at this time.
5. Pair the phone to a known-good vehicle (same model, year, and trim), and try to duplicate the problem.
Does the phone have the same problem on the known-good vehicle?
YES - Call the HFL support desk at 888-528-7876 to make sure the phone is configured correctly and has the correct software. If the phone is
configured correctly, it is either a characteristic of the HFL system, or a characteristic of the particular approved phone being used. Explain to your
client that this is a system characteristic. Another phone from the approved phone list may give more favorable results.
NO - Substitute a Known-good HandsFreeLink control unit and recheck. If the problem goes away, replace the original HandsFreeLink control
unit.
