Restore Your GM Truck’s Brain and Get Back on the Road
Is your Chevrolet Suburban, Silverado, or Tahoe acting up? Unexplained stalling, poor fuel mileage, a persistent Check Engine Light, and erratic transmission shifting are more than just annoyances—they’re classic signs of a failing Powertrain Control Module (PCM). As the central computer of your vehicle, a faulty PCM can cause a cascade of frustrating and hard-to-diagnose problems. I’ve seen it hundreds of times in my shop: a great truck sidelined by a failing electronic component. This isn’t just a part; it’s the solution to restoring your vehicle’s reliability and performance.
This replacement PCM, part number 9354896, is your direct-fit, hassle-free answer. We take the biggest headache out of the repair process: programming. Simply provide us with your vehicle’s VIN after purchase, and our technicians will flash this module with the latest official GM software updates specific to your truck. It arrives at your door ready for installation, saving you a costly trip to the dealership and the uncertainty of using a generic programmer. This ensures perfect communication between your engine, transmission, and other onboard systems, just like the day it left the factory.
Case Study: A Tricky Diagnosis
A customer brought in a 2000 Silverado 2500 with a complaint that stumped two other shops: intermittent stalling at stoplights, but only when the A/C was on. There were no consistent trouble codes, just a history of random misfire codes. After checking fuel pressure and ignition components, which were all fine, I focused on the live data from the PCM. I noticed the commanded idle speed would dip erratically right before a stall. This pointed to the PCM’s processing capability being compromised. We installed one of these pre-programmed PCMs, performed the security relearn, and the problem was gone for good. It’s often not a major mechanical failure, but the computer itself that’s the culprit.
Is Your Vehicle Showing These Symptoms?
- ✔ Check Engine Light is illuminated with codes like P0601 (Internal Control Module Memory Check Sum Error), P0602, or P0606 (PCM Processor Fault).
- ✔ The engine cranks but refuses to start.
- ✔ Noticeable decrease in fuel economy.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Intermittent stalling or rough idling.
- ✔ Failure to pass an emissions test due to communication errors.
A Straightforward Guide to Installation
Replacing your 2000 Suburban 1500 PCM is a job most DIYers can handle in their own driveway. Follow these steps for a smooth installation.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and secure it away from the post to prevent any accidental reconnection.
- Locate the PCM: On most GM trucks and SUVs from this era, the PCM is located in the engine bay, on the driver’s side, typically under or near the battery tray. You may need to remove the battery to gain access.
- Disconnect the Connectors: Carefully unplug the wiring harness connectors from the old PCM. These connectors have locking tabs that need to be released. Avoid pulling on the wires themselves.
- Remove the Old Module: Unbolt the old PCM from its mounting bracket. Keep the hardware as you may need it for the new module.
- Install the New PCM: Mount your new, pre-programmed PCM onto the bracket and securely plug in the wiring harness connectors. You’ll hear a click when they are properly seated.
- Reconnect the Battery: Reinstall the battery (if removed) and reconnect the negative battery terminal.
- Perform Security Relearn: Your vehicle may require a security relearn procedure to recognize the new PCM. This typically involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating two more times before starting the engine. Consult your owner’s manual for the specific procedure for your vehicle.

Frequently Asked Questions
Do I need to do any programming myself?
No. This PCM arrives fully programmed to your vehicle’s specific VIN with the latest GM software. All you need to do is provide your VIN at checkout and perform the security relearn procedure after installation.
Where do I find my VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a plate on the driver’s side dashboard visible through the windshield.
Is this a simple plug-and-play installation?
Yes, for the most part. The physical installation involves unplugging the old module and plugging in the new one. However, you will need to perform a simple ‘Security Relearn’ procedure, which syncs the new PCM to your vehicle’s anti-theft system. This procedure is easy and does not require special tools.
Will this fix my transmission shifting problems?
In many cases, yes. The PCM controls both engine and transmission functions. If the module itself is the source of the erratic shifting signals, replacing it with this correctly programmed unit will resolve the issue.
What if I have a different part number on my original module?
This module is a direct replacement for OEM part numbers 9354896, 09354896, and 19109040. As long as your vehicle is on the compatibility list, this module will function correctly.
