these steps:

Important: This procedure is a USB flash drive programming event. This IS NOT a standard TIS2WEB

requirement is 4 GB. The software downloaded to the USB flash drive can be used to update all vehicles involved in

this bulletin.
Any existing data on the USB flash drive will be erased during the TIS2WEB-to-USB flash drive download process.

To ensure important data IS NOT deleted from the USB flash drive, transfer the data from the USB flash drive onto

another approved data storage device BEFORE attempting to download software from TIS2WEB.

Once the software is downloaded to the USB, DO NOT add any data to the storage device.

Note: It is essential that the TIS terminal, MDI, Tech 2® and/or Scan Tool are updated with the latest software

available.

1. Update the radio using a USB FLASH DRIVE and the Service Programming System (SPS) with the file

available on TIS2WEB. Refer to the SPS procedures in SI.

NOT selectable in the “Available USB Drives” box.

8. Select: NEXT from the SPS Special Function screen.

9. Monitor the Progress Status bar at the bottom of the SPS Special Function screen.

Note: The files have been successfully loaded onto the USB flash drive when the Progress Status bar is completely

shaded and the SPS Special Function screen displays the following message: “Remove the USB stick and insert

into the vehicle USB port.”

10. Remove the USB flash drive from the computer when the Progress Status bar indicates that the software

download has been completed.

11. Press FINISH from the SPS Special Function screen. DO NOT wait for the Completion screen to appear on the

display.

Radio Software.
