Get Your Work Truck Back in Service, Fast.

A check engine light and a poorly running truck isn’t just an inconvenience—it’s a problem that costs you time and money. When your Silverado 2500, Sierra 2500, or Savana is down, your work stops. This direct-fit Engine Control Module (ECM), programmed specifically to your vehicle’s VIN with the latest GM software updates, is the professional-grade solution to get you back on the jobsite without the delay and expense of a dealership visit.

Common Symptoms & Your Solution

If your vehicle is experiencing any of the following issues, a failing ECM is a likely culprit. This module is the definitive solution for problems such as:

  • Persistent Check Engine Light (CEL)
  • Diagnostic Trouble Codes (DTCs) related to the processor, such as P0606
  • Engine stalling, stumbling, or rough idling
  • Poor fuel economy and loss of power
  • Complete no-start condition
  • Communication errors with other vehicle modules
  • Erratic transmission shifting behavior

Installing our programmed 12668986 ECM restores the critical communication between your engine’s sensors and components, ensuring your vehicle operates exactly as the manufacturer intended.

An Expert’s Note on Programming: Our technicians see it all the time: a generic, un-programmed module causing more headaches than it solves. That’s why we insist on programming every single programmed 12668986 ECM to your specific VIN with the latest factory software. This isn’t just about clearing a code; it’s about restoring the precise fuel, timing, and transmission parameters your vehicle’s powertrain was designed for. It’s the difference between a temporary patch and a long-term, reliable repair.

Frequently Asked Questions

How does the programming process work?

It’s simple. After you place your order, you provide us with your vehicle’s 17-digit VIN. Our technicians use this number to access the latest official GM software for your exact model and options. We flash the computer, verify it, and then ship it to you. It arrives ready to install.

Will I need to do anything after installation?

In many cases, the vehicle will start and run immediately. However, some vehicles may require a simple “relearn” procedure, such as a Case Relearn or security relearn, which can often be done without special tools. Instructions can typically be found online or in a service manual for your specific vehicle.

Is this a brand new part?

This is a quality-inspected, tested, and verified unit that meets or exceeds all original equipment specifications. Each module is carefully processed and programmed to ensure reliability and performance. The critical component is the correct, stable software programmed for your VIN.

Where do I find my vehicle’s VIN?

Your VIN can be found on your vehicle’s registration, insurance card, or on the vehicle itself. Look for a small plate on the driver’s side of the dashboard visible through the windshield, or on the sticker inside the driver’s door jamb.

How do I provide my VIN to you?

After you complete your purchase, you will receive instructions on how to send us your VIN. Please have it ready to ensure there are no delays in programming and shipping your programmed 12668986 ECM.
