tool).
NOTE:
The HDS laptop must be connected to an AC outlet during the reflash process and must be within a distance of 21 feet to the vehicle. Do not
allow the HDS laptop to go into sleep or hibernate mode during the reflash process. If this occurs, the Bluetooth connectivity between the
HDS laptop and the vehicle's HFL system will be dropped, and the reflash process will be interrupted. It will then be necessary to restart the
reflash procedure. See your laptop manufacturer's instructions or your system administrator for assistance to change these settings.
6. Press the audio preset No.2 button several times until the "A-diag UPDATE" screen appears on the i-MID.
7. Press the selector knob on the audio unit to change the HFL update screen. A four-digit PIN code appears. Write it down on a piece of paper or
on the RO, and leave it in the vehicle.
NOTE:
This PIN is required to complete the HFL update and to re-establish communication if the update process is interrupted. If this PIN is lost,
forgotten, or otherwise misplaced, and an interruption to the reflash process occurs, the HFL control unit will remain stuck in reflash mode,
and you will be unable to complete the update. If this happens, you must replace the HFL control unit.
