Vehicles With Navigation

NOTE:
Failure to follow the procedures and precautions in this bulletin may damage the HFL control unit.

1. Connect a jumper battery to the vehicle and leave it connected during the entire procedure to maintain a steady voltage.





2. Turn the ignition switch to ON (II).

3. Wait for the navigation system to boot up. When the disclaimer screen appears, press and hold the MAP/GUIDE, the DEST, and the CANCEL buttons for at least 5 seconds until the Select Diagnosis Items screen appears.





4. Select Self Diagnosis Mode.





5. The System Link screen appears and does an automatic diagnostic check. Wait a few moments while the process completes. Once completed, select HFL.





6. On the HDS laptop, double-click the HFL Control Unit Update icon to launch the Honda HFL (HFT) Control Unit Update Tool (HFL update tool).





7. On the HFL screen, select Software Update. The HFL system enters its reflash readiness mode.





8. The HFT software update screen displays a 4-digit PASS code. Write it down on a piece of paper or on the RO and leave it in the vehicle.





9. In the HFL update tool, click on the Bluetooth icon in the upper left corner of the screen to pair with the vehicle's HFL.





10. In the HFL update tool, the "Pair with HFL" window pops up. Wait a few seconds for the display to show "All Detected Bluetooth Devices." If no devices are found after about 30 seconds, click Refresh.





11. In the HFL update tool, once the Bluetooth device has been detected, enter the four-digit PASS code from the vehicle's display screen into the lower left-hand corner of the pop-up window. Click Pair to begin the pairing process.





12. Wait for the HFL update tool to complete the Bluetooth pairing process.





13. In the HFL update tool, the "Open Update Package" window pops up when the Bluetooth pairing process is 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.

^ If you see: "01.XX.XXX_(TO)_01.XX.XXX update," go to step 14.

^ If you see: "PartNumberFix update," go to PART NUMBER FIX UPDATE PROCEDURE - CR-V, Vehicles with Navigation.

NOTE:
There are a few early-production 2012 CR-Vs that require the PartNumberFix update. It must be completed before doing the HFL control unit update.





14. Click OK to begin the HFL control unit reflash process.





15. The HFL reflash process begins. Allow several minutes for the programming to complete. The blue bars indicate the programming status and progression.





16. In the HDS laptop, a pop-up window alerts you when the reflash process is finalizing, and then another pop-up informs you that the reflash process has completed.





17. In the HFL update tool, click OK when the pop-up window indicates the reflash process is complete.





18. The HDS laptop will indicate the update is complete, and automatically disconnects the Bluetooth connection from the HFL control unit. Close the HFL update tool by clicking on the "X" in the upper right-hand corner.

19. The vehicle's navigation screen may not indicate the same software version as shown on the HFL update tool. Do the following to confirm that the software in the HFL control unit has been updated:

^ Turn the ignition OFF.

^ Wait 10 seconds, then repeat steps 2 through 5 to place the navigation system in self-diagnosis mode.





20. On the navigation screen, verify the status of the reflash:

^ If successful, the reflash process is complete. Turn the ignition OFF.

^ If not successful, go to step 21.

21. Turn the ignition OFF.

22. Repeat steps 2 through 7 to prepare the HFL control unit for the update procedure, then go to step 23.





23. The navigation screen displays a 4 digit PASS code. Disregard this PASS code; you'll use the PASS code you wrote down in step 8.





24. In the HFL update tool, click on the Bluetooth icon in the upper left corner of the screen to pair with the vehicle's HFL control unit.





25. In the HFL update tool, the "Pair with HFL" window pops up. Wait a moment while Bluetooth devices are detected. If no devices are found after 30 seconds or so, click Refresh.





26. In the HFL update tool, once the Bluetooth device has been detected, enter the four-digit PASS code you wrote down in HFL CONTROL UNIT UPDATE PROCEDURE - CR-V, Vehicles with Navigation, step 8, into the lower left-hand corner of the pop-up window. Click Pair to begin the pairing process.

27. Do steps 13 through 20 to confirm the HFL control unit update was successful.
