HFL System Troubleshooting

HFL System Troubleshooting

NOTE:
- You must be able to duplicate the customer's concern to successfully diagnose the problem.
- Always use the customer's phone.
- Make sure the phone is approved and configured correctly. Online, go to www.handsfreelink.com, or call the HFL support desk at 888-528-7876.

1. Connect the HDS to the DLC.
2. Turn the ignition switch to 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 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 customer 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.
