Restore Peak Performance to Your GM Truck or SUV
Is your 2000 GMC Yukon XL 2500 suffering from erratic behavior, a persistent check engine light, or a frustrating no-start condition? The Powertrain Control Module (PCM), often called the vehicle’s brain, is the central command unit for your engine and transmission. When it begins to fail, it can cause a cascade of confusing and performance-robbing issues. This replacement PCM, part number 09354896, is the definitive solution to restore your vehicle’s factory operation, reliability, and efficiency.
Common Symptoms of a Failing Powertrain Control Module
A faulty PCM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, your PCM could be the culprit:
- ✔ Persistent Check Engine Light: You may see codes related to internal module memory errors, processor faults, or communication failures (U-codes).
- ✔ Engine Performance Problems: This includes rough idling, stalling, engine misfires, hesitation during acceleration, and a noticeable decrease in power.
- ✔ Poor Fuel Economy: A failing module can’t properly manage the air-fuel mixture, leading to a significant drop in MPG.
- ✔ Transmission Shifting Issues: The PCM controls shift points and line pressure. A bad module can cause harsh shifting, delayed engagement, or getting stuck in one gear.
- ✔ Intermittent or Complete No-Start: The PCM controls the fuel pump and ignition timing. If it fails to send the correct signals, your truck may crank but refuse to start.
- ✔ Failure of Emissions Tests: Incorrect sensor readings or internal faults will prevent the vehicle from passing state-mandated emissions inspections.
From the Diagnostic Bay
We had a 2000 Sierra 2500 (which uses this exact PCM) come into the shop with a bizarre issue. The owner had replaced the throttle position sensor, mass airflow sensor, and even the fuel pump chasing an intermittent stalling problem that only happened after the truck was fully warmed up. No specific codes were being stored, just a generic P0300 random misfire code that would pop up occasionally. After hours of diagnostics, we hooked up a scope to the PCM’s 5-volt reference circuit. We saw the voltage drop out sporadically as the module heated up, starving the sensors of power and causing the stall. A new, correctly programmed PCM fixed the issue instantly. It’s a classic reminder that the computer itself can be the source of the problem, not just the parts it controls.

Frequently Asked Questions
Is this module truly plug-and-play?
Because we program it to your VIN, it is as close to plug-and-play as possible. In most cases, you will only need to perform a security relearn procedure (also known as a VATS relearn), which takes about 30 minutes and involves cycling the key. Instructions are readily available online. Some vehicles may also require a Crankshaft Variation Relearn (CASE relearn) which requires a scan tool, but the vehicle will still run and drive without it.
How do I provide my VIN after purchase?
After you complete your purchase, you will receive an email with instructions on where to send your VIN. You can also add your VIN to the notes section during checkout. We cannot program or ship the module without this information.
Will this fix my specific problem or check engine light?
This PCM will correct any issues directly caused by a faulty original module. While it resolves the most common electronic problems, it’s essential to ensure your vehicle’s issues have been properly diagnosed. This part will not fix problems caused by other bad sensors, wiring faults, or mechanical failures.
What if my vehicle has non-factory modifications?
This module is programmed with standard factory GM software for your VIN. It is not designed for vehicles with significant powertrain modifications like different engine sizes, forced induction, or non-stock injectors. It is intended to restore the vehicle to its original operating specifications.
Do I need to send my old PCM back?
No core charge is required for this part. You do not need to return your old, faulty module to us.
