Is Your Suburban 2500 Acting Up?

If you’re dealing with a no-start condition, erratic shifting, a check engine light that won’t go away, or poor fuel economy in your 2005-2006 Suburban 2500, a failing Powertrain Control Module (PCM) is a very likely culprit. As the central computer for your engine and transmission, when the PCM starts to fail, it can cause a host of frustrating and hard-to-diagnose problems. You depend on your Suburban to be a reliable workhorse, and a faulty PCM can bring it to a dead stop.

Expert Pro Tip from 20+ Years on the Floor

Before you condemn your PCM, take a close look at the battery and its tray. On these GM trucks, the PCM is located right under the battery. I’ve seen countless cases where a leaking battery drips acid directly onto the PCM connectors and wiring harness, causing corrosion that mimics a failed module. Always disconnect the battery, remove it, and thoroughly clean and inspect the connectors with a good contact cleaner before replacing the PCM. This simple check can sometimes save you the cost of a new part.

Forget expensive dealership visits and programming fees. This is a genuine GM Powertrain Control Module, part number 89017749, that arrives at your door completely programmed to your vehicle’s specific Vehicle Identification Number (VIN). We flash it with the latest GM-certified software updates, ensuring optimal performance, fuel efficiency, and emissions control. It’s a true plug-and-play solution designed to get you back on the road with confidence.

Symptoms of a Failing 2005-2006 Suburban 2500 PCM:

  • ✔ Check Engine Light (CEL) illuminated with communication codes (like U0100).
  • ✔ Engine cranks but will not start.
  • ✔ Harsh or erratic automatic transmission shifting.
  • ✔ Noticeable drop in fuel economy.
  • ✔ Stalling, rough idling, or engine misfires.
  • ✔ Other warning lights on the dash appearing without reason.

Plug-and-Play Installation: No Dealer Visit Required

Installing your new PCM is a straightforward process you can do in your own driveway. All you need are basic hand tools. Here’s how simple it is:

  1. Safety First: Disconnect the negative terminal from your vehicle’s battery.
  2. Locate the PCM: On your Suburban 2500, it’s located under the battery tray on the driver’s side of the engine compartment.
  3. Access the Module: Remove the battery and the battery tray to gain clear access to the old PCM.
  4. Disconnect Harnesses: Carefully unclip the wiring harness connectors from the old module. Inspect them for any corrosion or damage.
  5. Swap the Modules: Unbolt the old PCM and install the new one in its place.
  6. Reconnect Everything: Securely plug the wiring harnesses into your new PCM and reinstall the battery tray and battery. Reconnect the negative battery terminal.
  7. Final Step: Your vehicle may require a security relearn procedure, which can typically be done without special tools. Instructions are readily available online or in your service manual.
