Is Your Chevrolet SSR Running Rough or Not Starting?
If your 2006 Chevrolet SSR is experiencing baffling electrical gremlins, poor performance, or has simply refused to start, the root cause is often a failing Powertrain Control Module (PCM). As the central computer of your vehicle, the PCM (also known as the Engine Control Module or ECM) is responsible for managing everything from fuel injection and ignition timing to transmission shifting and emissions control. When it fails, the symptoms can be widespread and frustrating, often leading to incorrect diagnoses and costly, unnecessary repairs.
From the Diagnostic Bay
We recently had a 2006 SSR in the shop with a classic case of intermittent failure. The owner complained of random stalling at traffic lights and a persistent, yet unpredictable, Check Engine Light. We scanned the codes and found a slew of communication errors with various sensors. After verifying the wiring harness and grounds were solid, we suspected the PCM. Swapping in a pre-programmed module like this one solved the problem instantly. The SSR ran smoothly, the codes cleared, and the owner was back on the road without a trip to the dealership. This highlights how a faulty module can mimic many other problems.
Common Symptoms of a Failing 2006 SSR Engine Control Module
A failing PCM can manifest in numerous ways. If you’re noticing any of the following issues, it’s a strong indicator that your vehicle’s main computer needs attention. Don’t let a faulty module keep your unique SSR off the road.
- ✔ Check Engine Light: The light is on, and you may have error codes related to module communication (U-codes) or multiple, unrelated sensor failures.
- ✔ No-Start Condition: The engine cranks but refuses to start, often due to a lack of fuel or spark command from the PCM.
- ✔ Poor Engine Performance: You may experience rough idling, hesitation during acceleration, stalling, or a noticeable decrease in power.
- ✔ Reduced Fuel Economy: An incorrect air/fuel mixture controlled by a failing PCM can cause your vehicle to consume more gasoline than usual.
- ✔ Transmission Shifting Issues: The PCM works with the transmission controller, and a fault can lead to harsh, erratic, or delayed shifting.
- ✔ Intermittent Problems: Issues that come and go with changes in temperature or driving time are a hallmark of failing electronic components inside the module.

Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM), or Engine Control Module (ECM), is the main computer in your vehicle. It controls all aspects of the engine and transmission to ensure optimal performance, fuel efficiency, and emissions. It takes data from sensors all over the vehicle and makes real-time adjustments.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it. You can typically find your VIN on the driver’s side dashboard (visible through the windshield) or on the driver’s side door jamb sticker.
Is any additional programming required after installation?
No. This module comes fully programmed to your VIN with the latest software. In most cases, it is a simple plug-and-play installation. Some vehicles may require a security relearn procedure (often called a CASE relearn or anti-theft relearn), which is a simple process that can be done without special tools. Instructions can be easily found online for your specific model.
Where is the module located on a 2006 SSR?
On the 2006 Chevrolet SSR, the Electronic Control Module is located in the engine bay, right next to the air filter box. Always disconnect the battery before attempting to remove or install the module.
Will this fix my specific problem?
While this module resolves the vast majority of issues listed above, proper vehicle diagnosis is always recommended. Please ensure that your vehicle’s wiring, grounds, and sensors have been checked to rule out other potential causes before replacing the control module.
Is this part compatible with other vehicles?
Yes, in addition to the 2006 SSR, this module is compatible with several Cadillac and Oldsmobile models, including the Aurora (01-03), DeVille (00-03), Eldorado (00-02), and Seville (00-03). The programming will be specific to the VIN you provide, ensuring correct function for any of these applications.
