Recommendation/Instructions
2015 Model Year Vehicles with Gen 10 OnStar System
Step 1: If 15086 is open in the Global Warranty Management system, complete it and evaluate OnStar operation before following this PI.
Step 2 (USA dealers only): If 15086 is not open/listed in Global Warranty Management, USA dealers should use the scan tool to note the Firmware Over-theAir (OTA) Version. If the OTA Version is 6708 or greater/newer or if you are a Canadian dealer, proceed to Step 3 below. If the OTA Version is lower/older
than 6708, order a replacement OnStar module using the special B101D ordering section found at issgm.com (ISS - Instrument Sales and Service website) and
outlined below:
ISS Website Navigation to Special B101D Ordering Section:
a.
Enter Parts Dealer Code and Zip Code to Log In
b.

Click “Confirm OnStar Order”
d.
Click “B101D-F0/3C DTC”

In most instances, ISS will process these special orders without requiring TAC approval but in some rare instances they may ask you to contact TAC for
documentation and approval purposes depending on the VIN reported.
Step 3: If a USA dealer finds that the OTA Version is 6708 or greater/newer or if you are a Canadian dealer, contact the GM TAC OnStar group with the
following information (DO NOT clear the DTCs):
a. OnStar Module Firmware Over-the-Air Version using GDS2.
b. OnStar Module STID (OnStar Customer Identifier) located on the OnStar Module or in the related GDS2 Data List.
c. The part number that is on the original OnStar module.
