Is Your GM Truck or SUV Acting Up? It Could Be The ECM.
If you’re experiencing baffling issues like a persistent check engine light, erratic engine performance, poor fuel mileage, or even a no-start condition, the problem might not be a faulty sensor or mechanical part. The culprit is often the very brain of your vehicle: the Engine Control Module (ECM), also known as the Powertrain Control Module (PCM). This critical component acts as the central computer, managing everything from fuel injection and ignition timing to transmission shifting and emissions control. When it begins to fail, it can create a cascade of problems that are frustrating and difficult to diagnose.
This replacement ECM, part number 19210067 (interchangeable with 12602010), is the definitive solution for a wide range of 2007-2008 GM vehicles, including the Buick Rainier, GMC Envoy, Chevy Trailblazer, and more. Don’t let a faulty computer keep your reliable truck or SUV off the road. We provide a professionally prepared module that gets you back in the driver’s seat without the hassle and expense of a dealership visit.
From the Diagnostic Bay
We recently had a 2007 Trailblazer come into the shop with a complaint of random stalling at stoplights and a transmission that felt like it was ‘confused’ during shifts. The owner had already replaced the throttle body and a couple of sensors with no success. Our diagnostic scan showed intermittent communication loss codes with the ECM. After confirming the wiring harness and grounds were solid, we pinpointed the fault to the ECM itself. The internal processors were failing, sending corrupt data to the rest of the vehicle. We installed one of our pre-programmed modules, performed the security relearn, and the truck ran perfectly. It’s a classic example of how a failing ‘brain’ can mimic a dozen other mechanical problems.
Symptoms of a Failing Engine Control Module
- ✔ Check Engine Light: The light is on, and you may have codes related to module communication (like U-codes) or multiple, unrelated sensor codes.
- ✔ Engine Performance Issues: You may notice rough idling, hesitation during acceleration, engine misfires, or a significant drop in power.
- ✔ Poor Fuel Economy: A failing ECM can’t properly calculate the air-fuel mixture, leading to a noticeable decrease in your MPG.
- ✔ Transmission Problems: The ECM works with the transmission controller. A fault can cause harsh shifting, delayed engagement, or getting stuck in one gear.
- ✔ Intermittent or Total No-Start: The vehicle may crank but refuse to start, or it may start unpredictably. This can happen when the ECM fails to control the fuel pump or ignition coils.
- ✔ Stalling: The engine may stall for no apparent reason, either while driving or when coming to a stop.
The Superior Solution: Our Programmed 2007 Rainier ECM
What sets our modules apart is the essential programming service we perform before it ever ships. A new or used ECM is just a metal box; it needs to be loaded with the correct software for your specific vehicle to function. We handle this critical step for you. When you provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN), our technicians will flash the module with the latest, most up-to-date software directly from GM. This not only ensures compatibility but also includes any performance and reliability improvements GM has released since your vehicle was new. This makes our 2007 Rainier ECM a true plug-and-play solution, saving you from towing your vehicle to a dealer and paying high programming fees.

Frequently Asked Questions
Do I need to have this module programmed?
No. The main benefit of our service is that we program the module for you before we ship it. All you need to do is provide your vehicle’s VIN during or after checkout. It will arrive ready to be installed.
What is a VIN and where do I find it?
The VIN is your 17-digit Vehicle Identification Number. You can find it on a metal plate on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Will I need to do any other procedures after installation?
In most cases, you will need to perform a security relearn procedure (also called a Passlock or anti-theft relearn). This procedure syncs the new ECM to your vehicle’s anti-theft system and can typically be done without special tools. It usually involves turning the key to the ‘ON’ position for 10-15 minutes, 3 times in a row. Some vehicles may also require a Crankshaft Position Sensor Variation Relearn (CASE Relearn), which may require a capable scan tool.
Is this a direct replacement for part number 12602010?
Yes, part numbers 19210067 and 12602010 are interchangeable GM service numbers for this specific Engine Control Module. This unit is a correct replacement for either number.
What happens if I don’t provide my VIN?
We cannot ship the module without your VIN. The programming is essential for the part to work in your vehicle. We will hold your order and contact you to get the VIN before we can complete the service and ship your part.
