Effortless Installation Guide
You don’t need to be a master mechanic to complete this job. With basic hand tools and this guide, you can confidently install your new PCM. Here are the steps:
- Safety First: Begin by disconnecting the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Old Module: On most compatible vehicles like the S10 Blazer, the PCM is found in the engine compartment, often on the passenger (RH) side near the firewall or fender.
- Disconnect Harnesses: Carefully unplug the electrical wiring harnesses connected to the old PCM. These connectors have locking tabs that may need to be gently pried up or squeezed to release.
- Swap the Units: Unbolt and remove the old, faulty module from its mounting bracket. Secure your new, pre-programmed PCM in its place.
- Reconnect and Secure: Firmly plug the wiring harnesses into the new module until they click into place. Reconnect the negative battery terminal and tighten it securely.
- Vehicle Security Relearn: In many cases, you will need to perform a simple security relearn procedure to sync the new PCM with your vehicle’s anti-theft system. This typically involves cycling the key in the ignition and waiting for a set period. Instructions will be provided.

Frequently Asked Questions
Do I need to get this module programmed by a dealer?
No. The main benefit of our service is that we program the module to your vehicle’s exact VIN before we ship it. This means it’s ready for installation right out of the box, saving you time and the high cost of dealer programming.
What is the security relearn procedure?
The security relearn, or anti-theft relearn, syncs the new PCM to your vehicle’s keys. It’s a simple process you can do yourself. Typically, you’ll turn the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’ for 10 seconds, and repeat this cycle three times. Your vehicle will then recognize the new module.
Where is the PCM located on a 2001 S10 Blazer?
On the 2001-2002 S10 Blazer and S15 Jimmy, the Electronic Control Module is located in the engine compartment on the right-hand (passenger) side, often mounted to the inner fender or firewall.
Will this fix my check engine light?
If the check engine light and associated codes (like P0601 – Internal Control Module Memory Check Sum Error) are being caused by a faulty PCM, then yes, this replacement will resolve the issue and allow the light to be cleared.
What information do you need from me after I order?
All we need is your 17-digit Vehicle Identification Number (VIN). You can find this on your vehicle’s registration, insurance card, or on the driver’s side dashboard visible through the windshield. Please provide it to us after checkout to ensure perfect programming.
