Is Your GM Truck or Van Running Rough?

If you’re dealing with a frustrating no-start condition, erratic engine behavior, or a check engine light that just won’t go away on your 1998-1999 GMC Yukon, the Powertrain Control Module (PCM) is often the culprit. As the central computer for your engine and transmission, its failure can cause a cascade of problems that are tricky to diagnose. This isn’t just a part; it’s the solution to getting your reliable truck back on the road.

This is a genuine, used OEM PCM that has been meticulously tested and is ready for installation. We take the guesswork and high cost out of the equation by programming the module specifically for your vehicle using your VIN. This ensures all factory settings and the latest GM software updates are loaded, making it a true plug-and-play solution.

Symptoms of a Failing GM PCM:

Over my 20+ years in the shop, I’ve seen these modules fail in a few common ways. If your vehicle is experiencing any of these, a replacement PCM is the likely fix:

  • โœ” Unexplained Check Engine Light with various communication or sensor codes.
  • โœ” Engine cranks but refuses to start.
  • โœ” Harsh or erratic automatic transmission shifting.
  • โœ” Poor fuel economy and loss of power.
  • โœ” Intermittent stalling, especially after warming up.

Real-World Diagnostic Story

“A customer’s ’99 Tahoe came in last week with an intermittent no-start that had three other shops stumped. They’d replaced the fuel pump and crank sensor, but the problem persisted. We hooked up our scope and saw the injector pulse signal was dropping out randomly. Instead of throwing more parts at it, we connected a test PCM, and the truck fired up every single time. It was a classic case of internal PCM failure due to heat cycles and age. This programmed module is the exact fix we used to get that customer’s truck running reliably again.”

Plug-and-Play Installation: No Dealer Visit Required

Because we program this 1998-1999 Yukon PCM to your vehicle’s specific VIN before shipping, you can avoid a costly trip to the dealership. The installation is straightforward for a DIYer with basic tools.

  1. Safety First: Disconnect the negative battery terminal and wait 10 minutes for the system to discharge.
  2. Locate the PCM: On most of these trucks and vans, it’s located in the engine compartment, typically on the driver’s side fender.
  3. Disconnect Connectors: Carefully unclip the wiring harness connectors from the old module. Inspect the pins for any corrosion or damage.
  4. Swap the Modules: Unbolt the old PCM and secure the new one in its place.
  5. Reconnect Everything: Firmly plug the wiring harnesses into your new PCM and reconnect the negative battery terminal.
  6. Security Relearn: You will need to perform a simple security relearn procedure (often called a Passlock relearn) which takes about 30 minutes and involves cycling the key. Instructions are readily available online for your specific model.
