NOTE: 

• Check the vehicle battery condition first .
• Before you troubleshoot, make sure to follow the General Troubleshooting Information .
• Check any official Honda service website for more service information about the HFL system.
• Once the symptom is duplicated, contact the HFL Customer Service. Many HFL issues are related to the cell phone and not the HFL system.
• Make sure the client's cell phone is properly paired.
• See if you can duplicate the symptom in a known-good vehicle under the same conditions. If you can, it is probably a characteristic of the system.
• Always use the client's cell phone to successfully diagnose the problem.
• Check the connectors for poor connections or loose terminals.
