Years ago, automotive repair just needed some standard tools, mechanical techniques, and basic diagnostics. We were limited to traditional gas-powered vehicles. Swap out some broken parts, tighten the fittings, and our cars were back on the road.<\/p>\n\n\n\n

Within the last decade, things have begun to shift and change. Today, your car is essentially a high-powered computer blazing down the highway at 70 miles-per-hour. While vehicles today are definitely safer and more efficient, an extra layer of frustration has formed: the software lock.<\/p>\n\n\n\n

Have you ever replaced a battery, a window motor, or a fuel injector, and your car still doesn’t run right or the dashboard lights still show every warning under the sun? That’s because the car’s computer hasn’t “met” the new part yet.

The “Pass-Thru” part is simple: the device is a secure bridge. It doesn’t store data itself. It allows the official factory information to “pass through” from the manufacturer to your vehicle’s computer.<\/p>\n\n\n\n

Why You Need One (And How It Saves You Money)<\/h2>\n\n\n\n

Until recently, OEM updates were mostly done within dealership service bays. If you needed an update needed the car to ‘learn’ it had a new part, you had to pay the “Dealership Tax.” These service calls could cost you $150 or more for an hour of labor.<\/p>\n\n\n\n
