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. We sell engine computers programmed to your vehicles’ VIN and correct calibrations, but it’s up to you to complete any necessary relearns or setup procedures (e.g., injector setup, crankshaft variation relearn). This ensures security features align perfectly with your vehicle’s system.
