Important Installation Notes
Upon installation, if the vehicle does not start, a theft relearn will need to be done using the GM programming system Tis2web/Techline Connect. This is the responsibility of the end user. Additionally, other relearns or setup procedures may be required, such as injector setup or crankshaft variation relearn. It’s essential to follow proper installation and relearn procedures to ensure security features align perfectly and prevent any issues.
