Restore Your GM Vehicle’s Performance and Reliability
Is your truck, van, or SUV suffering from frustrating and intermittent issues like a persistent check engine light, poor fuel economy, rough idling, or even a no-start condition? These are classic signs of a failing Powertrain Control Module (PCM). Your vehicle’s PCM is its brain, and when it falters, the entire system is compromised. This programmed 12602801 PCM is the definitive, hassle-free solution to restore your vehicle’s peak operational state and get you back on the road with confidence.
Common Symptoms & Your Solution
A faulty engine computer can cause a cascade of problems that are often misdiagnosed, leading to expensive and unnecessary repairs. If you’re experiencing any of the following, a failing PCM is the likely culprit:
- Unexplained Check Engine Light (CEL) with various codes (e.g., U-series communication codes, P0600-P0606)
- Engine stalling, sputtering, or misfiring
- Harsh or erratic transmission shifting
- Reduced engine power and poor acceleration
- Complete failure to start the engine
- Inaccurate dashboard gauge readings

We use your vehicle’s unique Vehicle Identification Number (VIN) to flash the module with the latest, most stable software updates directly from GM. This ensures perfect compatibility and optimal performance right out of the box.

An Expert’s Note on VIN Programming
As a technician with over two decades of experience, I’ve seen countless vehicle owners waste hundreds of dollars on a junkyard computer only to find it’s incompatible or creates new problems. The key is the software. Every vehicle has slight variations in its options and calibration. VIN-specific programming isn’t just a convenience; it’s a necessity for modern vehicles. It ensures the PCM communicates correctly with the transmission, anti-lock brakes, and security systems, preventing a host of issues that a generic or incorrectly programmed module would cause. This is the correct way to do the job right the first time.
Frequently Asked Questions
How do I provide my vehicle’s VIN?
After you complete your purchase, simply reply to your order confirmation email with your 17-digit VIN. You can also add it to the ‘notes’ section during checkout. We cannot ship your part until we receive this information.
Is this part difficult to install?
For most supported models, the PCM is in an accessible location (e.g., under the battery tray or in the engine compartment). Installation typically involves disconnecting the battery, unplugging the electrical connectors from the old module, swapping the hardware, and reconnecting everything. It’s a straightforward job for a DIYer with basic tools.
Will this module require any additional programming?
No, the core engine and transmission programming is complete. However, on many GM vehicles, you may need to perform a simple security relearn procedure that syncs the new PCM to your existing keys. This procedure takes 10-30 minutes and does not require any special tools. We can provide instructions for this process.
How can I be sure this will fix my vehicle’s issue?
This programmed 12602801 PCM is a guaranteed fix for a faulty module. While it resolves the vast majority of the symptoms listed above, we always recommend that a proper diagnosis is performed to rule out other potential causes like a bad sensor or wiring issue. If the PCM has been confirmed as the point of failure, this is your solution.
What do the different part numbers mean?
Manufacturers often release updated versions of a part over time. The numbers 12589462, 12602801, and 89017749 are all hardware-compatible service numbers for this specific module. We ensure the unit you receive is correct for your vehicle, regardless of the number on your original part.
