Restore Peak Performance to Your GM Truck or SUV
Is your 2001-2002 Silverado 3500 running rough, shifting erratically, or refusing to start? These are classic signs of a failing Powertrain Control Module (PCM), the central computer that manages your engine and transmission.

From the Diagnostic Bay
We had a 2002 Sierra 2500 in the shop that was driving the owner crazy. It had an intermittent stalling problem and a random misfire code that would jump between cylinders. The owner had already replaced spark plugs, wires, and even a couple of ignition coils with no luck. After hooking up our scanner and monitoring live data, we noticed the injector pulse width commands were erratic right before a stall. This pointed us away from the individual components and towards the central controller. We swapped in a pre-programmed PCM, and the truck ran perfectly. It’s a classic case where chasing individual symptoms can be costly; sometimes the problem lies with the computer making the decisions.
Is Your PCM Failing? Common Symptoms
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ A noticeable drop in fuel economy (MPG).
- ✔ The engine cranks but refuses to start (no-start condition).
- ✔ Communication errors with diagnostic scan tools.
- ✔ Failure to pass state emissions testing.

Installation Overview
On most 2001-2002 Silverado and Sierra pickups, the PCM is located in the engine bay on the driver’s side, under or near the battery. Installation is straightforward for a skilled DIYer or any professional technician.
- Disconnect the Battery: Always disconnect the negative battery terminal before working on any electronic components.
- Locate and Remove the Old PCM: Unplug the electrical connectors (they have locking tabs) and unbolt the module from its mounting bracket.
- Install the New PCM: Mount the new module and securely reconnect the electrical harnesses.
- Reconnect the Battery: Reattach the negative battery terminal.
- Perform Security Relearn: You will need to perform a security relearn procedure (often called a VATS relearn) to sync the new PCM with your vehicle’s anti-theft system. This procedure typically takes about 30 minutes and does not require special tools. Instructions are readily available online or can be provided upon request.
Frequently Asked Questions
Do I need to have this PCM programmed by a dealer?
No. This is the biggest benefit of our service. We program the module to your vehicle’s specific VIN before we ship it. This saves you the time, hassle, and expense of a dealership visit.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will provide clear instructions on how to do this. We cannot ship your part until we receive the VIN.
What is a VATS or CASE relearn, and will I need to do one?
After installation, you will need to perform a Vehicle Anti-Theft System (VATS) relearn. This syncs the new PCM to your keys and is required for the engine to start. It’s a simple procedure involving turning the key on and off in a specific sequence for about 30 minutes. A Crankshaft Variation (CASE) relearn may also be required to clear certain engine codes, which requires a capable bi-directional scan tool.
My original part number isn’t 12576160, but it’s on the compatible list. Will this work?
Yes. Manufacturers often consolidate part numbers. As long as your original part number is listed as compatible (e.g., 12200411, 12201281), this module will function as a direct replacement once programmed to your VIN.
Where is the PCM located on my 2002 Silverado?
On most 2001-2002 Silverado, Sierra, Tahoe, and Yukon models, the PCM is located in the engine compartment on the driver’s side, typically mounted to a bracket underneath the battery tray.
