Restore Peak Performance to Your GM Truck or SUV
Is your 2001-2002 Suburban 1500 suffering from frustrating and unpredictable engine problems? A persistent check engine light, poor fuel economy, erratic shifting, or even a no-start condition can sideline your vehicle and disrupt your life. These issues often point directly to a failing Powertrain Control Module (PCM). This isn’t just a part; it’s the brain of your engine, and when it falters, everything else does too. Get back on the road with confidence with this fully programmed, ready-to-install engine computer.
Common Symptoms & Your Solution
A failing PCM can manifest in numerous ways, often mimicking other component failures, which can lead to expensive and incorrect repairs. If you’re experiencing any of the following, our pre-programmed PCM is the definitive solution:
- Check Engine Light (CEL): Especially for internal module codes like P0601, P0602, P0604, or P0606.
- Engine Performance Issues: Stalling, rough idling, misfiring, or a significant loss of power.
- Transmission Problems: Harsh or delayed shifting, or getting stuck in one gear (limp mode).
- No-Start Condition: The engine cranks but refuses to start, often due to a lack of fuel injector or ignition coil command.
- Poor Fuel Economy: A sudden and unexplained drop in your vehicle’s MPG.

Expert Insight: The “Ghost in the Machine” Fixed
We recently worked with a customer whose 2002 Yukon XL had been to three different shops for a baffling intermittent stalling issue. They had replaced the fuel pump, crank sensor, and even the ignition switch, but the problem persisted. The vehicle wasn’t storing any clear trouble codes. After a quick consultation, we suspected the PCM was failing internally, specifically when it got hot. We sent them a 2001-2002 Suburban 1500 PCM programmed to their VIN. The customer installed it in their driveway in under 30 minutes. The stalling vanished immediately, and the truck has been running perfectly ever since. It’s a classic case of how a faulty computer can create phantom problems that are impossible to trace without replacing the core component.
Frequently Asked Questions
Do I need to send you my old computer?
No, there is no core charge or need to send us your original module. This is a direct purchase.
What information do you need from me?
After you place your order, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). This is critical for us to program the module correctly for your specific vehicle and its options.
Is any additional programming required after installation?
In most cases, no. The module is ready to install. However, on many GM vehicles, a Security Relearn procedure (also known as Passlock/Passkey) must be performed after installation, which takes about 30 minutes and does not require any special tools. Some vehicles may also require a Crankshaft Variation Relearn (CASE Relearn), which can be done with a capable scan tool.
How do I find my VIN?
Your VIN can be found on a sticker on the driver’s side door jamb, on a metal plate on the driver’s side of the dashboard visible through the windshield, or on your vehicle’s registration and insurance documents.
Will this fix my specific problem?
This programmed 2001-2002 Suburban 1500 PCM is designed to fix issues directly caused by a failing computer. While it solves the vast majority of electronic engine and transmission problems, it’s essential to ensure your vehicle has been properly diagnosed by a qualified technician first.
Which vehicles does this part fit?
This PCM is compatible with a wide range of 2001-2002 GM trucks, vans, and SUVs, including the Silverado, Sierra, Tahoe, Yukon, Express, Savana, and many more. Please refer to the detailed fitment list on this page to confirm it matches your specific model.
