NOTE: This bulletin applies to vehicles equipped with UConnect Hands Free
Communications (sales code RSP) that were built prior to October 02, 2005
(MDH 1002XX).

Overview:
This bulletin involves flash reprogramming the Hands Free Module (HFM) module.

Symptom/Condition:
The Hands Free Module (HFM) fails to operate causing the UConnect Hands Free
Communications system to not respond when system activation is attempted by the
customer. Further diagnosis may reveal that when the StarSCAN® scan tool is used to
read Diagnostic Trouble Codes (DTC's) the tool indicates that the module is not
responding. Other modules on the bus may display loss of communication with the HFM. If
the Hands Free Communication system is unresponsive then the HFM may require
electronic reset.

Diagnosis:
Attempt to reset (power reset) the HFM as follows:

1.    With the ignition switch in the “Off” position, remove the “Ignition Off Draw” (IOD) fuse and wait 10 seconds.

2.    Install the IOD fuse.

3.    Turn the ignition to the “On” position (engine not running).

4. After the module is reset, press the “Phone Button” on the rear view mirror to activate
the UConnect Hands Free system and to verify proper system operation (Fig. 1). Did
the UConnect Hands Free system reset and now operates properly?
      a. Yes >> Perform Repair Procedure.
      b. No >> This bulletin does not apply. Further diagnosis is required. Continue
         diagnosis as needed using the existing diagnostic procedures available in
         TechCONNECT under: Service Info, 8 - Electrical, Navigation/Telecommunication,
         Diagnosis & Testing.

NOTE: Do NOT replace the mirror for the above condition.

Special Tools/Equipment Required:

NPN	Battery Charger
9097A	Special Tool, Bluetooth UConnect Flash Adapter
CH9401	StarSCAN® Tool
CH9404	StarSCAN® Vehicle Cable
CH9409	StarSCAN® Documentation Kit
CH9410	StarSCAN® Ethernet Cable, 12 ft.
CH9412	StarSCAN® Software Update Device Kit
	TechCONNECT PC or equivalent
	StarSCAN® Software Update CD 6.03 or Higher

Repair Procedure: 

REPAIR PROCEDURE - USING THE INTERNET TO RETRIEVE THE FLASH FILE:

NOTE: USE THE StarSCAN® TO PERFORM THIS PROCEDURE.

NOTE: The StarSCAN® diagnostic scan tool fully supports Internet connectivity.
However, to take advantage of this feature you must first configure the
StarSCAN® for your dealership's network. Make sure the StarSCAN® is
configured to the dealership's network before proceeding. For instruction on
setting up your StarSCAN® for the dealer's network refer to either:
“DealerCONNECT > Service > StarSCAN and StarMOBILE tools > Online
Documentation”, or refer to the StarSCAN® Quick Start Networking Guide.
The StarSCAN® Quick Start Networking Guide is also available on the
www.dcctools.com website under the "Download Center".

NOTE: If this flash process is interrupted/aborted, the flash should be restarted. The
HFM may take up to 20 minutes to time out of the original flash process. A
power reset of the HFM, as performed above, may be required.

1.	Install a battery charger and verify that the charging rate provides approximately 13.5 volts. Set the battery charger to continuous charge. Do not allow the charger to time out during the flash process. Remove the charger from the battery when the flash process is complete.
2.	Connect the CH9404 StarSCAN® vehicle cable to the StarSCAN® and the vehicle data link connector (DLC).
3.	Power ON the StarSCAN®.
	The reprogramming procedure requires access to software and equipment that most owners do not have. The programming procedure will not be posted here. To see the specific instructions, you can obtain or view a copy of this TSB at your dealership or you can send me a message and I will email the details to you.
NOTE: Due to the HFM programming procedure, a DTC may be set in other modules (TCM, BCM, MIC, SKREEM, etc.) within the vehicle, if so equipped. Some DTC's may cause the MIL to illuminate. From the “Home” screen select “System View”. Then select “All DTCs”. Press “Clear All Stored DTCs” if there are any DTCs shown on the list.

Policy:    Reimbursable within the provisions of the warranty.
