Restore Peak Performance to Your GM Truck or SUV
Is your 1998-2000 Oldsmobile Bravada, Chevy S10, GMC Jimmy, or other compatible GM vehicle suffering from frustrating issues like a persistent check engine light, rough idle, poor fuel economy, or erratic shifting? These are classic symptoms of a failing Powertrain Control Module (PCM). As the central computer for your engine and transmission, a faulty PCM can cripple your vehicle’s performance and reliability. This direct-replacement PCM, part number 218-11787, is the definitive solution to get your vehicle running like new again.
Unlike generic modules that require expensive trips to the dealer for programming, this unit is delivered to you ready for installation. We take your vehicle’s unique Vehicle Identification Number (VIN) and program the module with the latest, most stable software updates directly from GM. This ensures perfect communication between all vehicle systems, restoring factory performance, emissions compliance, and drivability right out of the box.
From the Diagnostic Bay
We had a 1999 GMC Jimmy come in that had its owner completely stumped. The truck would run fine for about 15 minutes, then suddenly stall and refuse to restart for an hour. The owner had replaced the fuel pump, ignition coil, and crank sensor, but the problem persisted. After hooking up our professional scan tool, we noticed intermittent communication loss with the PCM right before it would stall. A failing internal processor was causing it to overheat and shut down. We installed one of our VIN-programmed PCMs, performed the quick security relearn procedure, and the Jimmy ran perfectly. It’s a great reminder that when you’ve chased all the common culprits, the vehicle’s main computer is often the root cause.

Frequently Asked Questions
Why do I need to provide my VIN?
Your Vehicle Identification Number (VIN) allows us to program the module with the exact software and calibrations your vehicle had from the factory, plus any available GM updates. This ensures perfect compatibility with your engine, transmission, and options for a seamless installation.
Is this module difficult to install?
Installation is straightforward for a DIY mechanic. It involves disconnecting the battery, unplugging the electrical connectors from the old PCM, unbolting it, and installing the new one in its place. Because it comes pre-programmed, no dealer visit is required. However, some vehicles may require a simple security relearn procedure, which can be done without special tools and takes about 30 minutes.
What is the difference between a PCM, ECM, and ECU?
These terms are often used interchangeably. PCM (Powertrain Control Module) is the most accurate for these GM vehicles as it controls both the engine and transmission. ECM (Engine Control Module) and ECU (Electronic Control Unit) are more general terms. For this application, they all refer to the same part.
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. It’s crucial to properly diagnose the vehicle first to ensure the fault codes aren’t being caused by a bad sensor or other component that the PCM is correctly identifying.
Is this a new or used part?
This is a professionally serviced original equipment part. Each module undergoes rigorous testing of its internal components and circuits to ensure it meets or exceeds OEM specifications for performance and longevity before being programmed for shipment.
