Restore Your GM Truck’s Core Performance and Reliability
Is your truck or SUV plagued by frustrating, intermittent issues? A check engine light that won’t go away, rough idling, stalling, or poor fuel economy can often be traced back to a failing Powertrain Control Module (PCM). As a technician with over two decades of experience, I’ve seen firsthand how a faulty PCM can send you chasing phantom sensor codes for weeks. It’s the brain of your vehicle, and when it’s not working right, nothing else will.
This isn’t just a replacement part; it’s a direct solution. We provide a high-quality PCM, part number 09354896, that is professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN). This critical step ensures all factory settings and the latest GM software updates are loaded before it even ships. The result is a module that’s ready for installation right out of the box, restoring the precise engine and transmission control your vehicle had when it was new.
Is Your GM Vehicle Showing These Signs of PCM Failure?
- ✔ Persistent Check Engine Light (CEL)
- ✔ Diagnostic Trouble Codes (DTCs) related to internal module failure, such as P0601, P0602, or P0606.
- ✔ Unexplained engine stalling or hesitation.
- ✔ Rough or erratic transmission shifting.
- ✔ A sudden, noticeable drop in fuel mileage.
- ✔ Complete no-start condition where the engine cranks but won’t fire.
- ✔ Communication errors with diagnostic scan tools.
From the Diagnostic Bay: The Silverado That Wouldn’t Start
A customer brought in a 2000 Silverado 2500 with a no-start condition that had stumped two other shops. The fuel pump was new, it had spark, and all the fuses were good. On the scan tool, I kept getting intermittent communication errors with the PCM. After confirming all power and grounds to the module were solid, I suspected an internal PCM failure. Instead of sending the customer to the dealership for a costly new module and programming, we ordered one of our VIN-programmed units. It arrived, we performed the simple security relearn, and the truck fired up on the first try. The customer saved hundreds and got his work truck back on the road in a day.
Solving Problems with a Programmed 2000 Suburban 2500 PCM
Choosing a pre-programmed 2000 Suburban 2500 PCM is the most efficient way to solve complex electronic issues. By programming the module with your VIN, we ensure it correctly communicates with your vehicle’s other systems, like the anti-lock brakes (ABS) and body control module (BCM). This eliminates compatibility conflicts that can arise from using a generic, un-programmed unit from a salvage yard, saving you from a mandatory and expensive trip to the dealership for flashing.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery and secure it away from the post.
- ✔ Locate the PCM: On most GM trucks like the Suburban, Silverado, and Sierra, the PCM is located under the hood on the driver’s side, typically below or next to the battery tray.
- ✔ Disconnect Connectors: Carefully unclip and remove the wiring harness connectors from the old PCM. Inspect the connectors for any corrosion or damage.
- ✔ Remove the Old Module: Unbolt the old PCM from its mounting bracket and remove it from the vehicle.
- ✔ Install the New Module: Mount your new, pre-programmed PCM into the bracket and securely re-attach the wiring harness connectors.
- ✔ Reconnect Battery: Re-attach the negative battery terminal.
- ✔ Perform Security Relearn: You will need to perform a simple security relearn procedure. This typically involves turning the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’, and repeating two more times. This allows the vehicle’s anti-theft system to recognize the new PCM.

Do I need to do anything after I install this 2000 Suburban 2500 PCM?
Do I need to do anything after I install this 2000 Suburban 2500 PCM?
Yes. After installation, you must perform a security relearn procedure (also known as a Passlock or VATS relearn). This is a simple process that you can do yourself in about 30 minutes with just the ignition key. It allows your vehicle’s anti-theft system to sync with the new PCM.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically add it as a note during checkout or reply to your order confirmation email. We cannot ship the module until we receive your VIN.
Is this part a direct fit?
Absolutely. This module is designed to be a direct-fit replacement for the original equipment on the vehicles listed in our compatibility chart. It uses the same mounting points and connectors.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the PCM (e.g., DTC P0601), this replacement module will resolve the issue. However, if the light is on due to a faulty sensor or another component, that separate issue will still need to be addressed.
