REPAIR PROCEDURE
NOTE:
• Failure to follow the procedures and precautions in this bulletin may damage the HFL control unit.
• A factory data reset will need to be done after completing the TCU software update. The factory data reset will
delete the client’s saved presets and settings (audio unit presets, Bluetooth paired phones, navigation).
1. Write down the client’s FM, AM, and SXM presets to restore after the update is complete.
2. Prepare the vehicle for the update.
• If the engine will be running, park the vehicle outside in a well ventilated area or attach an appropriate exhaust
vent. Go to step 2.
• If the engine will not be running, connect an active charger to the battery. Go to step 3.
3. Start the engine, and leave it running throughout the entire software update process. Go to step 4.
4. Turn the ignition to ON.
5. Wait for the navigation system to boot up. When the disclaimer screen appears, press and hold the MENU, NAV,
and BACK buttons at the same time for at least 5 seconds until the Select Diagnosis Items screen appears.
Page 3 of 12
6. Select Self-Diagnosis Mode.
7. The System Links screen will appear, and an automatic diagnostic check will start. After the process completes,
and the Press any icon if you want to see details message appears, select HFL.
8. On the i-HDS laptop, double-click the HFL control unit update icon to launch the Honda HFL (HFT) Control Unit
Update Tool (HFL update tool).
NOTE:
• The i-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 i-HDS laptop to go into sleep or hibernate mode during the reflash process. If this occurs, the
Bluetooth connectivity between the i-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.

Contact your IT support for additional help.

vehicle’s display screen into the lower left hand corner of the pop-up window. Click Pair to begin the pairing
process.

Page 7 of 12

complete. The HFL update tool automatically determines which version of the HFL software is present. The
compatible updates will be displayed on the HFL update tool. Click OK to begin the HFL control unit reflash
process.
Page 8 of 12
The HFL reflash process begins. Allow several minutes for the programming to complete. The blue bars indicate the
programming status and progression.
NOTE: Do not turn the engine OFF while the i-HDS laptop is transferring files to the HFL control unit. Doing so will
damage the HFL control unit. If the Bluetooth connectivity between the i-HDS laptop and the HFL control unit is lost,
the ignition must remain ON. Reboot the i-HDS laptop, and restart the HFL update tool. Make sure you use the fourdigit PIN you wrote down.
In the i-HDS laptop, a pop-up window alerts you when the reflash process is finalizing, then another popup tells you
that the reflash process has completed.
Page 9 of 12
16. In the HFL update tool, click OK when the pop-up window indicates the reflash process is complete and the HFL
screen indicates the update has completed.
NOTE: Failure to wait for both of the i-HDS laptop message Updates Complete!, and the HFL message Update

HFL control unit.
The HFL screen will indicate the HFL tool update has been completed.
NOTE: Selecting OK will return to the HFL screen, which will not show the newly updated software version.
Page 10 of 12

the HFL control unit. Close the HFL update tool by clicking the X in the upper right-hand corner.

pair the phone(s).
