On some 2015 LaCrosse, Regal, ATS, CTS Sedan (VIN A), Escalade models (with RPO AVF), SRX, XTS, Colorado, Corvette, Impala (VIN 1), Silverado, Suburban (with RPO AVF), Tahoe (with RPO AVF), Canyon, Sierra, and Yukon models (with RPO AVF) equipped with RPOs RAO (SRX Only), RAO + UA3/UY4, IO4, IO5, or IO6, there may be multiple infotainment display screen conditions. (Fig. 8) These conditions may include a blank display, the display screen stuck in incoming call view after a phone call, and a blank Rear View Camera display. In addition, other possible conditions include unavailable navigation screen audio content, USB issues, inoperative speech recognition, traffic messages and clock display issues.

For a complete list of possible conditions on specific infotainment systems, refer to #PI1375A.

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.
