Restore Your Ride’s Heartbeat
Is your truck or SUV feeling sluggish, unpredictable, or just not itself? A failing Powertrain Control Module (PCM) can be the hidden cause behind a host of frustrating issues, from a stubborn Check Engine Light to poor fuel economy and erratic shifting. It’s the brain of your vehicle, and when it’s not working right, nothing feels right. This pre-programmed PCM is the definitive, hassle-free solution to bring back the smooth, reliable performance you depend on. We take all the guesswork out of the equation by flashing the module with the latest GM software tailored specifically to your vehicle’s VIN. You get a component that’s ready to install right out of the box, letting you bypass expensive dealership programming fees and get back on the road with confidence.
Warning Signs Your PCM is Failing
If you’re experiencing any of the following symptoms, a faulty engine computer could be the culprit. This module is engineered to resolve these exact problems:
- ✔ Persistent Check Engine Light: Especially with internal controller error codes like P0601, P0602, P0604, or P0606.
- ✔ Engine Performance Issues: Stalling, rough idling, misfiring, or a noticeable loss of power can all point to a failing PCM.
- ✔ Transmission Problems: Harsh or delayed shifting, or getting stuck in a single gear (limp mode).
- ✔ No-Start Condition: The engine cranks but refuses to start, even with a good battery and starter.
- ✔ Poor Fuel Economy: A sudden and unexplained drop in your vehicle’s MPG.
- ✔ Intermittent Electrical Glitches: Gauges behaving erratically or other strange electronic behavior.
From a Seasoned Tech’s Playbook
I remember a customer with a 2002 Sierra 1500 who had been chasing a ghost for months. He’d replaced sensors, checked wiring, and was at his wit’s end with an intermittent stalling issue. The truck would just die at a stoplight with no warning. After checking everything else, we pinpointed the PCM. He was hesitant, worried about the cost and complexity. I showed him one of these pre-programmed units. The look of relief on his face when he realized it was a simple swap he could do in his own driveway was priceless. An hour later, he called back, overjoyed. The truck ran better than it had in years. That’s the power of a straightforward, correct solution.
Guided Installation to Restore Peace of Mind
Installing your new 2001-2002 Blazer S10 PCM is a manageable job for a DIYer with basic tools. Follow these steps for a successful replacement and get back to a worry-free drive.
- Safety First: Always begin by disconnecting the negative terminal of your vehicle’s battery to prevent any electrical shorts.
- Locate the Old Module: On most S10 Blazers and Jimmys, you’ll find the PCM in the engine bay, on the right-hand (passenger) side. For other GM trucks and vans, it’s typically under the hood near the battery.
- Disconnect and Remove: Carefully unplug the electrical harness connectors. They have locking tabs that need to be released. Once disconnected, unbolt the old PCM from its mounting bracket and remove it.
- Install the New PCM: Mount your new, pre-programmed module in the same location. Securely reconnect all the electrical harnesses, ensuring they click into place.
- Reconnect the Battery: Reattach the negative battery terminal and tighten it.
- Perform Security Relearn: Your vehicle’s anti-theft system needs to sync with the new PCM. This is a simple procedure (often called the “key relearn”) that typically involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating two more times. Consult your owner’s manual for the exact steps for your model.

Your Questions, Answered
Do I need to get this computer programmed?
No. The main benefit of our service is that we program the module for you before it ships. Simply provide your vehicle’s VIN during checkout, and we handle the rest, saving you a trip to the dealer.
What is the security relearn procedure?
It’s a simple process that syncs the new PCM with your vehicle’s anti-theft system so the engine will start. It typically involves cycling the ignition key and waiting for a set period. This procedure does not require any special tools and instructions are readily available online for your specific model.
Where is the PCM located on my 2001 Blazer?
On the 2001-2002 S10 Blazer and S15 Jimmy, the PCM is located in the engine compartment on the front passenger side, near the firewall.
Will this fix my check engine light for code P0601?
Yes, error code P0601 specifically indicates an “Internal Control Module Memory Check Sum Error.” This is a fatal flaw in the PCM itself, and replacing the module is the correct and necessary repair.
Is this a true plug-and-play part?
Almost! Because it arrives pre-programmed to your VIN, it eliminates the most difficult step. The only thing you’ll need to do after the physical installation is the simple, tool-free security relearn procedure to allow your vehicle to start.
