Are you tired of the check engine light glaring at you from the dashboard? Frustrated with your Blazer or Jimmy running rough, hesitating, or refusing to start? The brain of your vehicle’s engine management system, the Powertrain Control Module (PCM), is often the hidden culprit behind these perplexing issues. This isn’t just a replacement part; it’s a complete, worry-free solution. We deliver this PCM directly to you, fully programmed with the latest GM software updates, tailored specifically to your vehicle’s Vehicle Identification Number (VIN). It’s time to end the guesswork and restore the smooth, reliable performance you depend on.
Is Your Vehicle Trying to Tell You Something?
A failing PCM can manifest in ways that are easy to misdiagnose. If you’re experiencing any of the following, a faulty module could be the root cause:
- ✔ Persistent Check Engine Light (CEL) that won’t go away.
- ✔ Diagnostic Trouble Codes (DTCs) like P0601, P0602, P0606, or U-series communication codes.
- ✔ Unexplained stalling or engine cutting out while driving.
- ✔ Rough idling or engine misfires that new spark plugs and coils can’t fix.
- ✔ A sudden, noticeable drop in fuel economy.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Complete no-start condition where the engine cranks but won’t fire up.
Guided Installation for a Confident Fix
You don’t need to be a master mechanic to complete this repair. Our pre-programmed module makes the installation straightforward. Here’s a simple guide to get you back on the road:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Old PCM: On most 2001-2002 S10 Blazers and S15 Jimmys, the PCM is located in the engine compartment, on the passenger side firewall or inner fender. It’s a silver box with several large electrical connectors.
- Swap the Connectors: Carefully unclip the wiring harnesses from the old module. They are color-coded or keyed, so you can’t mix them up. Connect them firmly to your new, pre-programmed PCM.
- Mount the New Module: Secure the new PCM in the original mounting bracket. Ensure it’s snug and won’t vibrate excessively.
- Reconnect and Start: Reconnect the negative battery terminal. Your vehicle may require a security relearn procedure, which typically involves turning the key to the ‘On’ position for 10-15 minutes. Start the engine and enjoy the restored performance!
Expert Tip: Before condemning your PCM, always check your battery terminals and primary ground connections. A corroded or loose ground wire can mimic PCM failure by causing voltage drops and communication errors. A quick clean and tighten can sometimes save you a lot of diagnostic headaches.

Frequently Asked Questions
Do I need to do anything after I install it?
In most cases, no. Our programming makes it a plug-and-play part. Some vehicles may require a simple security relearn procedure, which involves cycling the key and waiting for 10-15 minutes. Instructions are readily available online for your specific model if needed.
What is a VIN and why do you need it?
The VIN (Vehicle Identification Number) is your car’s unique 17-digit serial number. It contains vital information about your vehicle’s engine, transmission, and factory options. We use it to load the exact, correct software from GM so the module communicates perfectly with your vehicle.
How long does the programming process take?
The programming is completed after your purchase and before we ship the item. Once you provide your VIN, we typically program and ship the module within one business day, ensuring you get your part as quickly as possible.
Is this a new or a used part?
This is a high-quality, inspected, and tested recycled OEM part. Each unit undergoes a rigorous verification process to ensure it meets or exceeds original factory standards for performance and reliability before being programmed for your vehicle.
My original part number isn’t an exact match, but it’s listed as compatible. Will it work?
Yes. Manufacturers often consolidate multiple part numbers into a single, updated service number. As long as your vehicle model and year are on our compatibility list and your original part number is one of the listed interchanges (12200411, 12201281, 12576160, 52369718), this module will be the correct, programmed replacement.
