HandsFreeLink 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.

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 - 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.
