Is Your Vehicle Running Rough? The Problem Might Be Its Brain.
The Engine Control Module (ECM) is the central computer of your vehicle, responsible for managing everything from fuel injection and ignition timing to emissions controls and transmission shifting. When it starts to fail, it can cause a cascade of confusing and frustrating problems that can be difficult to diagnose. If your 2006 Pontiac Solstice or other compatible GM vehicle is experiencing erratic behavior, poor fuel economy, or has an illuminated Check Engine Light that won’t go away, a faulty ECM is a very likely culprit.
Don’t let a failing computer keep you off the road. This genuine GM service part is the definitive solution to restore your vehicle’s performance, reliability, and efficiency. We take the guesswork and hassle out of the repair by pre-programming the module specifically for your vehicle using your VIN. This ensures that it arrives with the latest GM software updates, ready for a straightforward installation.
From the Diagnostic Bay
We had a 2008 Chevy Colorado come in that was driving the owner crazy. It would randomly stall at red lights, had a persistent P0606 (ECM Processor Fault) code, and the transmission was shifting harshly. The owner had already replaced the throttle body and a few sensors with no luck. After confirming power and grounds to the ECM were solid, we knew the internal processor was failing. Instead of a costly trip to the dealer for a new module and programming fees, we installed one of our VIN-programmed units. The entire process, including the security relearn, took less than an hour. The truck ran perfectly, the codes cleared, and the customer was thrilled to have their reliable vehicle back without the dealership price tag.
Symptoms of a Failing Engine Control Module
A failing ECM can manifest in numerous ways. If you’re noticing any of the following issues, it’s time to consider a replacement:
- ✔ Persistent Check Engine Light (CEL) with communication or processor-related codes.
- ✔ Engine stalling, stumbling, or misfiring for no apparent reason.
- ✔ A complete no-start condition where the engine cranks but won’t fire up.
- ✔ Noticeable decrease in fuel economy.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Failure to pass an emissions test.
- ✔ Intermittent issues with other electronic systems controlled by the ECM.
The Perfect Solution: A Pre-Programmed 2006 Solstice Engine Module
Replacing the ECM on modern vehicles isn’t as simple as just swapping the part. The module must be programmed with the correct software for your vehicle’s specific VIN, options, and emissions calibration. Our service eliminates this difficult step. By providing us with your VIN during checkout, you receive a 2006 Solstice Engine Module that is a direct-fit, plug-and-play solution. We handle the complex programming so you don’t have to pay for expensive dealership tools or labor.
This module is a direct replacement for multiple GM service numbers, including 12590032, 12602044, 12603530, 12605843, 12607096, 12630457, and 19210737. It has an extensive application list across many Buick, Cadillac, Chevrolet, GMC, Pontiac, Saturn, Isuzu, and Saab models. Please verify your part number and consult the detailed fitment list to ensure compatibility.
Installation Note
For the 2006 Pontiac Solstice, the ECM is located on the left-hand front frame rail. While the module is programmed for your vehicle, you may need to perform a simple Security Relearn Procedure after installation to sync the new ECM with your vehicle’s anti-theft system. This procedure can typically be done without special tools and instructions can be readily found online or in a service manual.
Frequently Asked Questions
Do I need to have this module programmed by a dealer?
No. This is the primary benefit of our service. We program the module with the latest GM software using the VIN you provide before we ship it. It arrives ready to be installed in your vehicle.
What is a VIN and where do I find it?
The VIN is your vehicle’s unique 17-digit identification number. You can find it on your vehicle’s registration, insurance card, or on a small plate on the driver’s side of the dashboard, visible through the windshield.
Will this fix my car’s problem for sure?
This part will correct any issues directly caused by a failing ECM. If your vehicle exhibits symptoms like a no-start condition, random stalling, internal processor fault codes, or communication errors with the module, this is the correct solution. However, it will not fix problems related to other faulty sensors or mechanical parts.
Is any other procedure required after installation?
In most cases, you will need to perform a Security Relearn Procedure to sync the new ECM with your vehicle’s immobilizer system. Some vehicles may also require a Crankshaft Position Sensor Variation Relearn (CASE Relearn), which may require a capable scan tool.
My car isn’t a 2006 Solstice. How do I know this fits?
This ECM fits a very wide range of GM vehicles. The best way to confirm fitment is to match the service number from your original module to one of the numbers listed (12590032, 12602044, 12603530, etc.) or to find your exact year, make, and model in the comprehensive compatibility list on this page.
