SPECIAL TOOLS/EQUIPMENT REQUIRED:

REPAIR PROCEDURE:





1. Locate the HFM USB Connector (Fig 1).

NOTE:
Some later build vehicles may have the connector located on a short take off out from the wire harness behind the lower left side trim panel.

NOTE:
This is not the same as the USB port located on the radio).





2. Connect the wiTECH USB Cable to the HFM USB connector (Fig 2).
NOTE: Do not connect cable to the PC until instructed by wiTECH.

NOTE:
Install a battery charger to ensure battery voltage does not drop below 13.2 volts. Do not allow the charging voltage to climb above 13.5 volts during the flash process.

CAUTION:
Do not interrupt vehicle power, cycle ignition, or remove the USB cable while performing software reflash. If the flash process is interrupted and the HFM part number cannot be returned upon attempting to restart flash, then module replacement will be necessary. If the HFM is able to report its part number, after an interrupted flash, restart the flash process to fully reprogram the module.

3. Use the wiTECH Diagnostic Application to reflash the HFM module. Help using the wiTECH Diagnostic Application for flashing Hands Free Module is made available through the wiTECH Diagnostic Application. For instructions select the "HELP" tab on upper portion of the wiTECH window, then "HELP CONTENTS." This will open the Welcome to wiTECH Help screen where help topics can be selected.

NOTE:
wiTECH has been updated to store the large update file(s) to the local computer's hard drive. This will reduce the time required to perform this procedure after the first update is run.

4. Read, and follow carefully, the warnings and instructions in ALL popup messages before acknowledging the message or proceeding further.





NOTE:
A module reset may be required in the event that an abort recovery is necessary. If the HFM is unable to report a part number after an interrupted flash attempt, reset module power by removing fuse F131, from the passenger side fuse block, for 10 seconds (fig 3).
