Summary
This Service Bulletin provides information on the Canadian OnStar Cellular Communication Upgrade for GM passenger cars and light-duty trucks from 2000 to 2015. The upgrade is necessary due to the decommissioning of 2G CDMA networks in Canada.
The bulletin outlines the necessary steps for dealerships to upgrade vehicles with OnStar equipped with 2G CDMA technology to 3G or 4G LTE technology. This includes software calibrations, hardware installation, and customer communication.
The upgrade is available for vehicles with active OnStar service plans, and customers will be notified by OnStar when their hardware is available. Dealerships will receive upgrade kits for new vehicles in their inventory, and technicians will install the hardware and program the module using the Service Programming System (SPS).
The bulletin also includes information on part ordering, labor operations, and warranty replacements.
