Restore Peak Performance to Your GM Truck or SUV
Is your 2000 GMC Yukon XL 1500, or another compatible GM vehicle, suffering from perplexing issues like a persistent check engine light, erratic shifting, poor fuel economy, or a no-start condition? These are classic signs of a failing Powertrain Control Module (PCM), the central computer that governs your vehicle’s engine and transmission. Don’t let a faulty computer keep you off the road. This replacement PCM, part number 9354896, is the reliable, direct-fit solution to get your vehicle running like new again.
This isn’t just a generic part off the shelf. We take the guesswork out of the repair by pre-programming the module specifically for your vehicle. After your purchase, simply provide us with your Vehicle Identification Number (VIN), and our technicians will flash the unit with the latest, most stable software updates directly from General Motors. This ensures seamless integration and optimal performance, correcting factory bugs and improving drivability. Your vehicle’s specific parameters, from engine size to transmission type and axle ratio, are all accounted for, making installation as straightforward as possible.
From the Diagnostic Bay
We had a 2000 Sierra 1500 (which uses the same PCM) come into the shop with a complaint the owner described as ‘haunted’. The transmission would intermittently refuse to shift out of first gear, the gauges would flicker, and it would randomly stall at red lights. No codes were stored consistently. After chasing down grounds and testing sensors for two days, we focused on the PCM. We swapped in a known-good, programmed unit, and every single issue vanished. The original PCM had internal circuit board failures that were causing unpredictable data corruption, essentially confusing all the other vehicle systems. It’s a great reminder that when multiple, unrelated electronic systems act up, the central computer is often the culprit.
Solving Problems with a Replacement 2000 Yukon XL 1500 PCM
A failing PCM can manifest in numerous ways, often mimicking other component failures. Replacing your old, faulty module with this correctly programmed unit is the definitive fix for a wide range of electronic and performance-related problems. This part is a direct replacement for part numbers 19109040, 09354896, and 9354896, ensuring broad compatibility across many popular GM trucks and cars from that era.
Common Symptoms of a Failing PCM
- ✔ Persistent Check Engine Light (CEL) with various trouble codes
- ✔ Rough or unstable idling
- ✔ Decreased fuel efficiency
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Engine stalling or hesitation during acceleration
- ✔ Complete no-start condition where the engine cranks but won’t fire
- ✔ Failure to pass state emissions testing
This module is located on the driver’s side of the engine bay, under the battery tray, on most compatible trucks and SUVs like the Yukon, Tahoe, and Silverado. Installation involves disconnecting the battery, removing the old unit, installing the new one, and reconnecting the battery. In some cases, a security relearn or Crankshaft Variation (CASE) relearn procedure may be necessary, which can be performed with a capable scan tool.
Frequently Asked Questions
Why do I need to provide my VIN?
Your Vehicle Identification Number (VIN) contains critical information about your vehicle’s specific options, including engine size, transmission type, and emissions equipment. We use the VIN to load the exact GM-certified software for your vehicle, ensuring perfect compatibility and function right out of the box.
Is this part difficult to install?
For someone with moderate mechanical skill, the physical installation is straightforward. It typically involves disconnecting the battery and removing a few bolts. The most critical part is ensuring the VIN-specific programming is correct, which we handle for you. Some vehicles may require a security or CASE relearn procedure after installation, which may require a mechanic with a proper scan tool.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the PCM itself, then yes, this part will resolve the issue. However, if the light is on due to a faulty sensor or another component, you will still need to diagnose and repair that separate issue. This PCM will ensure the vehicle’s computer is operating correctly and reading sensors properly.
Is this a plug-and-play module?
Because we program it to your VIN, it is as close to plug-and-play as possible. It eliminates the need for expensive dealership programming. However, as mentioned, some GM vehicles of this era require a security relearn procedure to sync the new PCM with the vehicle’s anti-theft system. This is a simple procedure that can be found online or performed by any competent mechanic.
Where is the PCM located on my 2000 Yukon XL 1500?
On the 2000 GMC Yukon XL 1500, as well as similar models like the Silverado, Sierra, and Tahoe, the PCM is located in the engine compartment on the driver’s side, mounted to a bracket beneath the battery tray.
