End the Frustration of a Failing Engine Computer
Is your truck or van leaving you stranded? A flickering check engine light, rough idling, stalling, or unpredictable shifting can turn every drive into a stressful gamble. These aren’t just annoyances; they’re classic signs that your vehicle’s brain—the Powertrain Control Module (PCM)—is failing. This isn’t just a part; it’s the command center for your engine’s performance and reliability. When it falters, your vehicle’s dependability disappears. This replacement module is your direct path to restoring that lost confidence and getting your workhorse back on the road, running stronger than ever.
Warning Signs and How to Overcome Them
- ✔ Eliminate Stubborn Check Engine Lights: Finally clear persistent diagnostic trouble codes (DTCs) like P0601, P0602, P0605, and P0606, which directly point to an internal module failure.
- ✔ Restore Smooth, Consistent Performance: Say goodbye to hesitation, poor fuel economy, and erratic engine behavior. Regain the smooth acceleration and power you depend on.
- ✔ Solve No-Start & Stalling Nightmares: A faulty PCM can prevent your engine from starting or cause it to stall unexpectedly. This module ensures your vehicle starts reliably every time.
- ✔ Correct Erratic Transmission Shifting: Restore crisp, predictable gear changes by providing the transmission with accurate data from the engine.
- ✔ Guaranteed Solution: We program this module with the latest GM software updates using your vehicle’s unique VIN. It’s a precise, tailored solution, not a generic, one-size-fits-all part.
From the Trenches: A Mechanic’s Tale
“I had a customer with a ’98 Express work van, a plumber who was losing jobs because his van would stall randomly. He’d replaced sensors and wires, completely frustrated. We traced it to a failing PCM. Installing a pre-programmed module like this one was the key. We had him back on the road in under an hour. He called a week later just to say thanks—his van hadn’t run that smoothly in years. It’s not just about fixing a part; it’s about restoring someone’s livelihood and peace of mind.”
Effortless Steps for a Confident Fix
You don’t need to be a master mechanic to complete this repair. Our goal is to empower you with a straightforward solution. Follow these simple steps to install your new module.
- Safety First: Begin by disconnecting the negative terminal on your vehicle’s battery to prevent any electrical shorts.
- Locate the Old Module: On most of these trucks and vans, you’ll find the PCM in the engine compartment, typically on the driver’s or passenger’s side fender well.
- Disconnect and Remove: Carefully unplug the wiring harnesses. They have locking tabs that may need to be gently pried up. Once disconnected, unbolt the old module from its bracket.
- Install the New PCM: Mount your new, pre-programmed module in the same location and securely bolt it in place.
- Reconnect Everything: Plug the wiring harnesses back into the new module. You’ll hear a click as they lock into place. Finally, reconnect the negative battery terminal.
- Perform Security Relearn: Your vehicle will likely require a simple security relearn procedure to recognize the new PCM. This can typically be done in your driveway with just the key and takes about 30 minutes. Instructions are readily available online for your specific model.

Frequently Asked Questions
Do I need to program this module?
No, you don’t! That’s the best part. We handle all the programming for you before we ship it. Just provide us with your vehicle’s VIN after you place your order, and we’ll flash the module with the latest GM software specific to your truck or van.
What is a VIN and where do I find it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your vehicle. You can easily find it on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Will this fix my check engine light?
If your check engine light is caused by a faulty PCM (indicated by codes like P0601, P0605, etc.), then yes, this module is the correct solution. However, it’s always best to have the codes professionally diagnosed to ensure the PCM is the root cause of the problem.
Is the security relearn procedure difficult?
Not at all! For most GM vehicles of this era, the security relearn (also known as the Passlock relearn) is a simple, 30-minute process that involves turning the key to the ‘On’ position for 10 minutes, three times in a row. It requires no special tools and can be done right in your driveway.
How long does it take to get my programmed module?
Once we receive your VIN, programming is typically completed within one business day. We then ship the module to you, ready for installation.
