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 vehicle’s VIN and correct calibrations, but it’s up to you to do the vehicle theft deterrent relearn, as well as any other relearns or setup procedures (e.g., injector setup, crankshaft variation relearn). Please note that this is a critical step to ensure your vehicle’s security and performance.
