End the Frustration and Restore Your Vehicle’s Performance
Is your truck or van acting possessed? Unpredictable stalling, rough idling, a check engine light that won’t quit, and poor fuel economy can turn a reliable workhorse into a source of constant stress. These aren’t just annoyances; they’re symptoms of a failing Powertrain Control Module (PCM), the vital computer that orchestrates your engine’s performance. This isn’t a problem you have to live with. Our pre-programmed engine computer is the definitive solution, designed to restore your vehicle’s factory performance and give you back the confidence you deserve behind the wheel.
We take the guesswork and complexity out of the repair. Simply provide your vehicle’s VIN during checkout, and our experts will flash this module with the latest GM-certified software specific to your 2002 Escalade EXT. This ensures a seamless, plug-and-play installation, getting you back on the road quickly without the need for expensive dealership programming or specialized tools. It’s the straightforward fix for a complex problem.
Warning Signs Your PCM is Failing and Benefits of Replacement
- ✔ Check Engine Light On: Often with communication error codes like P0601, P0602, or P0606, indicating an internal module fault.
- ✔ Erratic Engine Behavior: Experiencing random stalling, stumbling, or hesitation that you can’t seem to trace to any other component.
- ✔ Poor Shifting or Transmission Issues: The PCM controls transmission logic, and a faulty one can cause harsh shifts, delayed engagement, or incorrect gear selection.
- ✔ No-Start Condition: If the PCM can’t communicate properly, it may fail to fire the spark plugs or fuel injectors, leaving you stranded.
- ✔ Reduced Fuel Economy: A failing module can’t optimize the air-fuel mixture, leading to wasted gas and more trips to the pump.
- ✔ Restore Smooth Operation: A new, correctly programmed module brings back the crisp throttle response and smooth power delivery you remember.
Guided Installation for a Confident Repair
You don’t need to be a master mechanic to complete this job. With basic hand tools and a little patience, you can have your vehicle running right in about an hour. Our pre-programmed module makes it simple.
- Safety First: Always begin by disconnecting the negative terminal on your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: On most compatible trucks and SUVs, the PCM is located under the hood, on the driver’s side, often under or near the battery tray.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be released. Then, unbolt the module from its mounting bracket.
- Install the New PCM: Mount your new, VIN-programmed module in the same location. Secure the bolts and firmly reconnect the electrical harnesses until they click into place.
- Power Up: Reconnect the negative battery terminal. The vehicle is now ready to start with its new brain. In some cases, a security or CASE relearn procedure may be needed, which can be done with many common scan tools.

Do I need to get this programmed by a dealer?
No. We handle all the programming for you before we ship the part. Simply provide your VIN at checkout, and it will arrive ready to install, saving you time and a costly trip to the dealership.
Is this a difficult part to install myself?
For most DIYers with basic tools, this is a straightforward installation that typically takes less than an hour. Our step-by-step guide above walks you through the process.
How do I know if this is the exact part I need?
The best way to confirm is to match the part number on your existing module to one of the compatible numbers listed (52369718, 12200411, 12201281, 12576160). You can also verify your vehicle is on our fitment list. If you’re still unsure, feel free to contact us with your VIN.
What is a CASE relearn and will I need to do one?
A Crankshaft Variation (CASE) relearn synchronizes the new PCM with your engine’s crankshaft position sensor. While the vehicle will start and run without it, performing a CASE relearn (which can be done with many professional-grade scan tools) is recommended for optimal performance and to clear a potential P1336 code.
What happens if I don’t provide my VIN?
Providing your VIN is essential. We cannot program and ship your module without it, as the software is specific to each vehicle. This ensures your vehicle operates correctly and all systems communicate as they should.
