Restore Your Truck’s Core Performance and Reliability
Is your 2000 Chevy Tahoe or GM truck running rough, stalling unexpectedly, or showing a persistent Check Engine Light? These aren’t just annoyances; they’re often signs that the vehicle’s central computer—the Powertrain Control Module (PCM)—is failing. As a technician with over two decades of experience under the hood, I’ve seen firsthand how a faulty PCM can create a cascade of frustrating, hard-to-diagnose problems. This isn’t just a part; it’s the brain of your engine and transmission, and when it’s not right, nothing is.
We offer a dependable and straightforward solution: a replacement Powertrain Control Module, part number 09354896, that arrives at your door ready to install. The biggest hurdle with PCM replacement is typically the programming. A blank module is useless without the correct factory software. We eliminate that step entirely. Simply provide your vehicle’s VIN during checkout, and our experts will flash the module with the latest, most stable GM software specific to your truck. This ensures seamless communication between all vehicle systems and restores the performance and efficiency you’ve been missing. Getting a reliable 2000 Tahoe Powertrain Control Module shouldn’t be a complicated ordeal, and with our service, it isn’t.
From the Diagnostic Bay: The Ghost in the Machine
I remember a 2000 Silverado—same platform as the Tahoe—that came into my shop with an intermittent no-start condition that had stumped two other mechanics. It would run fine for days, then refuse to start, with no consistent trouble codes. After hours of checking fuel pressure, spark, and wiring harnesses, I focused on the PCM. On a hunch, I monitored the 5-volt reference signal from the PCM to the sensors. During a no-start event, the voltage was erratic. The PCM’s internal voltage regulator was failing intermittently under specific temperature conditions. We installed a correctly programmed PCM, and the truck never had the problem again. It’s a classic example of how a failing computer can mimic a dozen other issues, making a quality, correctly programmed module the only true fix.
Is Your Vehicle Showing These Symptoms?
A failing PCM can manifest in numerous ways. If you’re experiencing any of the following, this module is likely the solution you need.
- ✔ Check Engine Light is on with codes like P0601 (Internal Control Module Memory Check Sum Error), P0606 (ECM/PCM Processor Fault), or other communication errors.
- ✔ Your engine cranks but refuses to start intermittently or at all.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ A noticeable drop in fuel economy for no apparent reason.
- ✔ The engine stalls, stumbles, or misfires while driving or at idle.
- ✔ Failure to pass an emissions test due to module-related faults.
A Straightforward Guide to Installation
Installing your new 2000 Tahoe Powertrain Control Module is a job most DIYers can handle with basic tools. Following these steps will help ensure a smooth process.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the PCM: On most of these trucks and SUVs, the PCM is located in the engine bay, on the driver’s side, typically under or near the battery tray.
- Disconnect the Connectors: Carefully unclip and remove the electrical wiring harness connectors from the old module. They have locking tabs that need to be released. Avoid pulling on the wires themselves.
- Remove the Old Module: Unbolt the PCM from its mounting bracket. It’s usually held in place by a few small bolts.
- Install the New Module: Mount your new, pre-programmed PCM onto the bracket and securely fasten the bolts.
- Reconnect Everything: Plug the wiring harness connectors firmly into the new module until they click into place. Reconnect the negative battery terminal.
- Perform Security Relearn: Your vehicle’s anti-theft system (PassLock/VATS) will need to be synchronized with the new PCM. This is a simple procedure that typically involves turning the key to the ‘ON’ position for 10-15 minutes. Instructions are readily available online for your specific model.

Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to load the exact GM-certified software for your truck’s specific engine, transmission, and options. This ensures perfect compatibility and performance, eliminating the need for a trip to the dealer for programming.
Is this a plug-and-play part?
Almost. Because we pre-program it to your VIN, the module is ready to be installed. However, you will need to perform a simple Security Relearn procedure, which takes about 10-15 minutes and requires no special tools. This syncs the new PCM with your vehicle’s anti-theft system.
Will I need to do a CASE Relearn?
A Crankshaft Variation Relearn (CASE Relearn) may be necessary to prevent a P1336 trouble code. While many vehicles run perfectly without it, it is recommended for optimal performance. Most local repair shops can perform this procedure for a small fee if needed.
What if I have the wrong part number?
This module replaces several part numbers, including 09354896, 19109040, and 9354896. As long as your vehicle is on our compatibility list and you provide a valid VIN, we guarantee it will be programmed correctly for your application.
Is this a new or used part?
This is a high-quality, inspected, and tested recycled OEM part. Each unit undergoes a rigorous verification process to ensure it meets or exceeds original factory specifications before being programmed with the latest GM software.
