We have recently aquired a General Motors Factory Scan Tool called the Tech 2, this is the same tool used at GM dealerships. It is capable of retrieving vast amounts of  information from your cars various on board computers. Such as engine, trans, abs, air bag, steering, heating & ac systems to name a few. It is also capable of reprogramming the many computers on your car. These software updates are continuously released by GM to solve various problems. Just stop by our shop and for no charge we will run your vin number from your car in our database to see if your car has any updates. If there are updates available we can perform the reprogram procedure for you. This is available on GM cars from 1995 to present. Thanks for your interest!!
