Is your dependable 1996 GM truck, van, or SUV suddenly unreliable? Stalling at intersections, refusing to start, or running rough can bring your work or family life to a grinding halt.

This direct-fit 16208546 Programmed ECM is the definitive solution to restore your vehicle’s performance and get you back on the road with confidence.

Expert Insight: Why VIN Programming is Non-Negotiable
Back in 1996, GM’s OBD-II systems were becoming more complex. The ECM didn’t just manage the engine; it was integrated with the anti-theft system (Passlock/VATS), transmission controls, and various body options. Simply swapping a used computer from another truck won’t work—the vehicle won’t start due to a security mismatch. Our VIN programming service correctly syncs the replacement 16208546 Programmed ECM to your vehicle’s unique configuration, making the installation as simple as it gets for a DIY mechanic or professional shop.
