Important Installation Notes:
Upon installation, if your vehicle does not start, a theft relearn may be required 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 is the buyer’s responsibility to perform any necessary relearns or setup procedures.
