Restore Peak Performance to Your 1996 GM Truck or Van
Is your reliable 1996 Chevrolet Express 2500, GMC Savana, or S10 Blazer suddenly running rough, stalling, or showing a persistent Check Engine Light? These are classic signs that the brain of your engine, the Electronic Control Module (ECM), may be failing. This vital component controls everything from fuel mixture and ignition timing to transmission shifting and emissions. When it falters, your vehicle’s performance and reliability suffer. This replacement ECM, part numbers 16208546 and 16244210, is the definitive solution to get your vehicle running like new again.
Unlike a generic part from a local store, this ECM is delivered to you fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). We install the latest, most stable software updates from General Motors, ensuring optimal performance and compatibility. This critical step eliminates the need for an expensive trip to the dealership for programming, saving you time, money, and hassle. It’s a true plug-and-play solution designed for a straightforward installation.
From the Diagnostic Bay
We had a 1996 GMC Yukon come into the shop with a complaint of intermittent stalling and a check engine light that previous mechanics couldn’t solve. They had replaced the throttle position sensor and the idle air control valve, but the problem persisted. After hooking up our scanner, we noticed erratic data from the ECM. Instead of throwing more parts at it, we swapped in a known-good, properly programmed ECM. The stalling vanished, the engine idled smoothly, and all data readings stabilized. It’s a powerful reminder that the ECM is the foundation of engine management, and a faulty one can mimic many other sensor failures.

Frequently Asked Questions
Why is providing my VIN so important?
Your vehicle’s VIN (Vehicle Identification Number) allows us to load the exact GM-specified software for your engine, transmission, and emissions equipment. This ensures the ECM works perfectly with your vehicle’s systems without any additional programming, making it a true plug-and-play installation.
Is this part difficult to install?
For most 1996 GM trucks and vans, the ECM is located in the engine bay, typically on the driver’s side. Installation involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and then reversing the process with the new one. It’s a straightforward job for a DIYer with basic tools.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the ECM, then yes, this part will resolve the issue. We recommend having your vehicle scanned for diagnostic trouble codes (DTCs) to confirm the ECM is the likely cause before ordering.
What is the difference between part numbers 16208546 and 16244210?
These are interchangeable GM service numbers for the same hardware. Our module is a direct replacement for either part number. Once programmed to your VIN, it will function identically to the original unit.
Do I need to perform a security relearn procedure?
For some 1996 GM vehicles, a simple security relearn procedure (often called a Passlock relearn) may be necessary after installation. This procedure is easy to perform and typically involves turning the key on and off in a specific sequence. Instructions are readily available online or in service manuals.
