REPAIR PROCEDURE
NOTE
Before updating the software, write down the client's audio unit presets.
1. From your computer's desktop, open Acura Firmware Downloader. Refer to Job Aid Acura Firmware Downloader
for additional information. Make sure that the USB drive tool is empty and formatted to FAT 32.
2. Enter the VIN. This is important as the software can be different depending on the trim level. Enter the service
bulletin number, then select the download icon when the correct software is found.
3. Once the download is complete, return to the vehicle.
4. Prepare the vehicle for the update by doing either of the following:
•

If the engine will be running, park the vehicle in a well-ventilated area or attach an exhaust vent.

•

If the engine will not be running, connect an active charger to the battery so it does not die during the update.

5. Insert the USB drive tool into the USB port.
