You may tue what you want to tell your technician with the terms "LITERATURE INFORMATION SERVICE" this referring to Technical Service Bulletins, commonly known as TSB.

GM bulletins are intended for use by professional technicians, NOT a \015\012"do-it-yourselfer". They are written to inform these technicians of \015\012conditions that may occur on some vehicles, or to provide information \015\012that could assist in the proper service of a vehicle. Properly trained \015\012technicians have the equipment, tools, safety instructions, and know-how\015\012 to do a job properly and safely. If a condition is described, DO NOT \015\012assume that the bulletin applies to your vehicle, or that your vehicle \015\012will have that condition. See your GM dealer for information on whether\015\012 your vehicle may benefit from the information.

Additionally, is good to know, when the "check engine" lights turn on, the vehicle's main computer is warning you about a fault detected by some sensor, resulting in a malfunction of any component. Generally are referred to emission (most simple), but may be another type of codes or problem. I suggest you ask fault code was found in the PCM (Powertrain Control Module) before it was removed (and the check engine light turn off), knowing this number code, we could provide additional details about the failure, possible ways test, discard and solutions.

Good luck and keep in touch.
