An updated software calibration has been released to address these conditions. Update the Human Machine Interface (HMI) Module using a USB flash drive and the Service Programming System (SPS) with the files available on TIS2Web.

The USB flash drive programming event is not a standard TIS2Web programming event. Use TIS2Web to download the updated version of the software for the vehicle that is being programmed to minimize the chance of flashing the wrong software into the HMI module.

After USB programming has been completed, reprogram the HMI module using SPS with the latest calibrations available on TIS2Web.

The vehicle modules must go to sleep for five minutes after programming the HMI module. If not, the vehicle may have a blank screen, no audio, no touch response, or the wrong splash screen may appear on the screen. If this happens, turn off the vehicle and wait the required five minutes before starting vehicle again.
