Is Your GM Vehicle Running Rough? Restore Its Performance Today.
If you’re experiencing frustrating issues like a persistent check engine light, unpredictable stalling, rough idling, or a complete failure to start, a faulty Powertrain Control Module (PCM) is often the culprit. This vital component is the brain of your vehicle’s engine, and when it fails, it can cause a cascade of problems that leave you stranded and stressed. This isn’t just an inconvenience; it’s a loss of the reliability you depend on. We offer the definitive solution to get your car back on the road, running smoothly and efficiently just like it should.
Common Symptoms & Your Solution
A failing engine computer can manifest in numerous ways. If you’re noticing any of the following, it’s a strong indicator that your PCM needs attention. This replacement unit is designed to correct these exact problems:
- Check Engine Light (CEL) Illumination: Often with diagnostic trouble codes (DTCs) like P0601, P0605, or P0606, indicating internal module failure.
- Engine Stalling or Misfiring: The engine may cut out unexpectedly while driving or at a stop.
- No-Start Condition: The engine cranks but refuses to start, or doesn’t crank at all.
- Poor Fuel Economy: A sudden and unexplained drop in your vehicle’s gas mileage.

Frequently Asked Questions
What exactly is a PCM?
The Powertrain Control Module (PCM) is your vehicle’s main computer. It controls all aspects of engine and transmission function, such as fuel injection, spark timing, and transmission shift points, to ensure optimal performance, fuel economy, and emissions.
How do I provide my vehicle’s VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is specific to your exact vehicle.
Is any additional programming needed after installation?
No. This module arrives pre-programmed to your VIN and is ready for installation. In some cases, a security relearn procedure (often called a CASE relearn) may be required, which can typically be done without special tools. Instructions are widely available online for this simple process.
What if my original part number is slightly different?
This module replaces both 12209624 and 12210234. If your module has one of these numbers and your vehicle is on the compatibility list, this is the correct part for you. The programming to your VIN ensures it functions perfectly.
Is this a brand new part from the dealer?
This is a quality, tested replacement part that has been expertly prepared and programmed with the latest software for your vehicle. It provides a reliable and affordable alternative to a costly new part from the dealership.
