HFL System Troubleshooting
- Before doing this troubleshooting, refer to General Troubleshooting (see INTRODUCTION ) to make sure the phone is compatible and configured correctly.
- You must be able to duplicate the customer's concern to successfully diagnose the problem.
- Always use the customer's phone to successfully diagnose the problem.
- Make sure the phone is Honda approved and configured correctly. Online, go to handsfreelink.honda.com, or call the HFL support desk at 888-528-7876.
- Make sure the phone is approved by checking handsfreelink.honda.com, or call the HFL support desk at 888-528-7876.
Is the Bluetooth phone approved?
YES - Go to step 2.
NO - Explain to the customer that the cell phone is not approved. Recommend they get a phone that does appear on the handsfreelink.honda.com website.
- Check if the cell phone has any special requirements (software version, configuration, etc.). Call the HFL support desk at 888-528-7876 for help.
Is the correct software version loaded and is the phone properly configured?
YES - Go to step 3.
NO - Explain to your customer that the cell phone software needs to be updated or the cell phone needs to be configured properly. If the HFL support desk is able to help you configure the phone, explain the proper settings, otherwise direct your customer to contact their cell phone manufacturer or carrier.
- Connect the HDS to the DLC (see GENERAL TROUBLESHOOTING INFORMATION ).
- Turn the ignition switch to ON (II).
- Go to HF LINK/TEL in BODY ELECTRICAL.
- Check for DTCs.
Are any DTCs indicated?
YES -Repair the indicated DTCs, and recheck.
NO -Go to Step 5.
- Try to duplicate the problem or have the customer demonstrate the problem.
Can you duplicate the problem?
YES -Go to Step 6.
NO -The system is OK at this time.
- 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 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 (see CONTROL UNIT INPUT TEST/REPLACEMENT ), and recheck. If the symptom/indication goes away, replace the original HandsFreeLink control unit (see CONTROL UNIT INPUT TEST/REPLACEMENT ).
