Restore Your Truck’s Peak Performance and Reliability
Is your 2001-2002 S10, Sonoma, or other GM vehicle suffering from frustrating and intermittent issues? Stalling, rough idling, poor fuel economy, and a persistent check engine light are often signs that your vehicle’s central computer has failed. The Powertrain Control Module (PCM) is the brain of your engine and transmission, and when it malfunctions, it can disrupt your entire driving experience. This replacement PCM is the definitive solution to bring your vehicle back to life, programmed specifically for your vehicle for a hassle-free installation.
Is Your Vehicle’s Brain Failing? Common Symptoms of a Bad PCM
A faulty engine computer can manifest in numerous ways, often mimicking other mechanical problems. If you’re experiencing any of the following, a failing PCM could be the culprit:
- Check Engine Light: Particularly for internal module error codes like P0601, P0602, or P0606.
- No-Start or Hard-Start: The engine cranks but refuses to start, or only starts after many attempts.
- Poor Performance: Noticeable loss of power, hesitation during acceleration, and decreased fuel efficiency.
- Erratic Shifting: The automatic transmission may shift harshly, at the wrong times, or not at all.
- Engine Stalling: The engine may die unexpectedly while driving or when coming to a stop.

Expert Insight: A common mistake is installing a used module without proper programming. The Vehicle Identification Number (VIN) is more than just a serial number; it’s the key that unlocks your vehicle’s specific configuration—from the engine and transmission to the axle ratio and tire size. Our VIN-matching process ensures that this new ‘brain’ speaks the exact same language as the rest of your truck, which is the secret to a successful and lasting repair.
Frequently Asked Questions
Do I need to have this module programmed by a dealer or mechanic?
No. The main benefit of our service is that the module arrives at your door fully programmed and ready for installation. We use your VIN to load the correct software before we ship it, saving you time and money.
What information do you need from me?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. This is critical for us to program the module correctly for your specific make, model, and options.
Is this the same as an ECM or an ECU?
Yes. The terms Powertrain Control Module (PCM), Engine Control Module (ECM), and Engine Control Unit (ECU) are often used interchangeably. For these GM vehicles, this single unit controls both the engine and transmission functions.
Will I have to perform a security relearn procedure?
Yes, on most GM vehicles of this era, you will need to perform a simple security relearn, also known as the Passlock relearn. This procedure syncs the new module with your vehicle’s anti-theft system and typically involves turning the key to the ‘ON’ position for 10-15 minutes, three times in a row. It requires no special tools.
Will this fix my check engine light?
If the check engine light is on due to an internal fault with the original PCM (like a P0601 code), this replacement will solve the problem. However, if the light is on for another reason, such as a faulty oxygen sensor or EGR valve, you will still need to address that separate issue.
Does this module fit vehicles other than the S10/Sonoma?
Absolutely. This is one of the most common PCMs for GM vehicles from the early 2000s. It is compatible with a wide range of trucks, vans, and SUVs like the Silverado 1500/2500/3500, Sierra 1500/2500/3500, Tahoe, Suburban, Yukon, Escalade, and Express/Savana vans. Please verify the part number to ensure it matches your application.
