Restore Your Vehicle’s Performance and Reliability
Is your 2006 Chevrolet SSR or other compatible GM vehicle suffering from perplexing issues like a persistent check engine light, erratic shifting, poor fuel economy, or even a no-start condition? These are common signs of a failing Powertrain Control Module (PCM), the electronic brain of your vehicle. This replacement PCM, part number 12573503, is the definitive solution to restore your vehicle’s factory performance and get you back on the road with confidence. It serves as a direct replacement for service numbers 12562481, 12571591, and 12573650, ensuring wide compatibility.
The Heart of Your Engine’s Operation: A Pre-Programmed 2006 SSR PCM
The PCM is one of the most critical components in a modern vehicle. It meticulously manages and monitors dozens of sensors and actuators to control everything from the air-fuel mixture and ignition timing to transmission shift points and emissions systems. When it begins to fail, the symptoms can be widespread and difficult to diagnose. Intermittent electrical gremlins, false sensor readings, and declining performance are often traced back to a faulty module. Our process eliminates the guesswork and the need for expensive dealership programming. We flash this module with the latest, most stable software updates from GM, specifically matched to your vehicle’s unique Vehicle Identification Number (VIN). This ensures seamless integration and optimal operation right out of the box.
From the Diagnostic Bay
We had a 2006 SSR come into the shop with a complaint of intermittent stalling and a check engine light for a random misfire that just wouldn’t go away. The owner had already replaced the plugs, wires, and even a coil pack with no success. After hooking up our professional scan tool, we noticed the live data for the crankshaft position sensor was dropping out sporadically, but the sensor itself tested fine. This pointed us directly to the PCM. The internal processor was failing under heat, causing it to lose critical sensor data. We installed a VIN-programmed PCM just like this one, performed the security relearn, and the truck ran perfectly. The owner was thrilled to have his SSR back to its powerful, reliable self without wasting any more money on unnecessary parts.
Common Symptoms of a Failing PCM
- ✔ Persistent Check Engine Light (CEL) with various trouble codes
- ✔ Engine stalling, stumbling, or hesitating during acceleration
- ✔ Harsh or erratic automatic transmission shifting
- ✔ A noticeable decrease in fuel economy
- ✔ Failure to pass state emissions inspections
- ✔ Complete no-start or intermittent starting issues
- ✔ Communication errors with diagnostic scan tools
Why Choose a VIN-Programmed Module?
Ordering a PCM programmed to your VIN is the most efficient and reliable way to complete this repair. An unprogrammed module from a dealership or parts store would require you to have the vehicle towed to a shop with expensive, specialized equipment for flashing. Our service handles this critical step for you. By providing your VIN at checkout, you receive a unit that is ready for installation. In most cases, the only additional step required is a simple security relearn procedure, which can often be performed in your own driveway without any special tools. This saves you significant time, money, and the hassle of coordinating with a repair facility.

Please verify your original part number (SERV.NO) to ensure compatibility. This module replaces 12573503, 12562481, 12571591, and 12573650.
Frequently Asked Questions
Do I need to send you my old PCM?
No, there is no core charge or need to send your original module to us. This is an outright purchase, allowing you to get your vehicle repaired faster.
What information do you need to program the module?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN). Please provide it during or after checkout. This ensures we load the correct GM-certified software for your specific vehicle configuration.
Is any additional programming required after installation?
Our programming covers the engine and transmission operating system. However, you will likely need to perform a security relearn procedure (also known as a VATS relearn) to sync the new PCM with your vehicle’s anti-theft system. This procedure can typically be done without special tools and instructions are widely available online.
What is the warranty on this 2006 SSR PCM?
This part comes with our standard warranty, which covers any defects in the module itself. Please refer to our warranty page for complete details and terms.
Will this fix my check engine light?
If the check engine light and associated symptoms are caused by a faulty PCM, this part is the correct solution. However, it’s crucial to ensure your vehicle’s issues have been properly diagnosed, as other failing sensors or wiring problems can sometimes mimic PCM failure.
