#17386-02: Customer Satisfaction Program – SDGM and BYOM2+ Radio Software Updates – (May 21, 2018)
|Revision Description: A labor time adjustment has been made in the Claim Information Section for Labor Operation 9103688 and an “Important” statement has been added before Step 1 of the Update Procedure. Please discard all previous copies of bulletin 17386-01.
||The reprogramming of the vehicles involved in this field action will be initially attempted by OnStar through in-vehicle prompts from the radio display. The new software updates will enhance the functionality of the vehicle’s Serial Data Gateway Module (SDGM) and the Bring Your Own Media (BYOM) radio. The over-the-air update process will be rolled out to vehicle owners in phases beginning April 2018 through August 2018. However, if the remote vehicle update is unsuccessful or the customer declines this service, dealers will be required to reprogram the vehicle. This program is in effect until April 30, 2020.
All involved vehicles are identified by Vehicle Identification Number (VIN) on the Investigate Vehicle History (IVH) screen in GM Global Warranty Management (GWM) system. During the service write-up process, dealership personnel should check IVH to determine if installation of the new software package has already been completed. If the remote vehicle update has been downloaded or installed, DO NOT install the update via USB. Otherwise, proceed to Update Procedure Using TIS2WEB (USB Download).
Involved vehicles are marked “open” on the Investigate Vehicle History screen in GM Global Warranty Management system. This site should always be checked to confirm vehicle involvement prior to beginning any required inspections and/or repairs.
||Certain 2017 model year Chevrolet Bolt EV vehicles need to be reprogrammed with an updated software package. Depending on the vehicle’s configuration, it may require two updates. The software updates will improve phone connectivity, display resolution, rear camera operation, and prevent instances of intermittent screen freezing. The updates will also remove certain video playback functionality and improve the ability to perform software updates to the radio.
||OnStar will update vehicles remotely through in-vehicle prompts from the radio display. However, some customers may decline the vehicle update or the update is attempted, but is not successful. In such cases, dealers will be required to reprogram the vehicle with the new software updates.
