HFL System Troubleshooting

NOTE:

- Before doing this troubleshooting, refer to General Troubleshooting Information Initial Inspection and Diagnostic Overview to make sure the phone is compatible and configured correctly. You can also check online at www.acura.com/handsfreelink.
- You must be able to duplicate the client's concern to successfully diagnose the problem.
- Always use the client's phone.
- Make sure the phone is Acura approved and configured correctly. Online, go to www.acura.com/handsfreelink, or call the HFL support desk at 888-528-7876.
- Also check what features are approved as some approved phones may have features that are not compatible with the HandsFreeLink system.

1. Make sure the phone is approved by checking www.acura.com/handsfreelink, or call the HFL support desk at 888-528-7876.

Is the Bluetooth phone approved?

YES -

Go to step 2.

NO -

Explain to the client that the cell phone is not approved. Recommend they get a phone that does appear on the www.acura.com/handsfreelink website.�

2. Check the features of the approved phone at www.acura.com/handsfreelink, or call the HFL support desk at 888-528-7876.

Are all the features approved?

YES -

Go to step 3.

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 3.

3. Connect the HDS to the DLC.

4. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.

5. Check for DTCs.

Are any DTCs indicated?

YES -

Repair the indicated DTCs, and recheck.�

NO -

Go to step 6.

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 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 call center 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 Service and Repair.�
