Is Your GM Truck or SUV Running Rough?
If you’re dealing with a frustrating no-start condition, erratic engine behavior, stalling, or a persistent Check Engine Light that just won’t go away, the problem often points directly to a failing Powertrain Control Module (PCM). As the central computer for your engine, when the PCM starts to fail, it can cause a cascade of issues that can be difficult to diagnose. I’ve seen it hundreds of times in my shop: perfectly good sensors and mechanical parts get replaced, but the root causeโthe PCMโis overlooked.
The Direct Solution: A Pre-Programmed PCM
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take a quality-tested PCM, service number 28042802, and flash it with the latest official GM software calibration specifically for your vehicle. All we need is your Vehicle Identification Number (VIN) during checkout. This process ensures that the module communicates perfectly with your engine, transmission, and all related systems, restoring the performance and reliability you depend on.
From the Shop Floor: A Real-World Scenario
“A customer’s 2004 Hummer H2 came in last month with an intermittent misfire and what he described as ‘lazy’ acceleration. He’d already replaced plugs and coils, with no luck. After connecting my scan tool, I noticed the fuel trim values were erratic and the ignition timing was jumping around without reason. This pointed away from a mechanical fault and toward the control system. We identified a failing driver circuit within his original PCM. Installing one of our pre-programmed modules solved the problem instantly. Itโs a classic failure mode for these units, and a new PCM is the only correct fix.”

Plug-and-Play Installation: No Dealer Visit Required
You can install this module yourself with basic hand tools. Follow these steps for a successful installation:
- Safety First: Disconnect the negative battery terminal and wait at least 15 minutes to allow the system’s capacitors to discharge.
- Locate the PCM: On most compatible trucks and SUVs like the Silverado or Tahoe, it’s under the hood on the driver’s side, near the battery. On models like the 2003 SSR or Envoy, it’s located next to the air filter box.
- Disconnect Connectors: Carefully release the locking tabs on the wiring harness connectors and pull them straight out from the module. Never force them.
- Remove the Old Module: Unbolt the PCM from its mounting bracket and remove it from the vehicle.
- Install the New Module: Seat your new, pre-programmed PCM into the bracket and secure it. Reconnect the wiring harnesses, ensuring they click firmly into place.
- Reconnect Battery: Reattach the negative battery terminal. Your vehicle is now ready to start. A security relearn procedure may be required, which typically involves turning the key to the ‘ON’ position for 10-15 minutes.
