Recommendation/Instructions
An updated software calibration has been released to address the above conditions. Update the HMI Module using a
USB FLASH DRIVE and the Service Programming System (SPS) with the files available on TIS2WEB. Refer to the
SPS procedures in SI.
Important: This procedure is a USB flash drive programming event. This IS NOT a standard TIS2WEB
programming event. This procedure requires a USB 2.0 flash drive. The minimum USB flash drive capacity
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.
After USB programming has been completed, reprogram the HMI module, this time using the Service Programming
System (SPS) with the latest calibrations available on TIS2WEB. Refer to the SPS procedures in SI.
Clear any DTCs.
Important: The vehicle modules MUST go to sleep for 5 minutes after programming the HMI module. If not, the
vehicle may not have sound, blank screen, no touch response or the wrong splash screen may appear on the
screen. If this happens, shut off vehicle and wait the required 5 minutes before starting vehicle again.
