Expert Diagnostic Tip
Before replacing your ECM, always perform a thorough check of the basics. Ensure your battery is fully charged and that the main power and ground connections to the computer are clean, tight, and free of corrosion. A bad ground can mimic the symptoms of a failed ECM, and verifying these connections can save you time and money. This Programmed 12670335 ECM is the solution for a confirmed module failure.
Frequently Asked Questions
What is the process after I place my order?
After you complete your purchase, you must provide us with your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information. Once we have your VIN, our technicians will program the module with the latest GM software specific to your vehicle and ship it out to you.
Is this ECM ready to install right out of the box?
Yes, the module arrives fully programmed for your vehicle’s engine and transmission operation. In some vehicles, a simple security relearn procedure (often called a CASE relearn or anti-theft relearn) may be required after installation. This procedure can typically be done without special tools and instructions can be found online or in a service manual.
How do I find my vehicle’s VIN?
Your VIN can be found on your vehicle’s registration, your insurance card, or on the vehicle itself. Look for a small metal plate on the driver’s side of the dashboard visible through the windshield, or on the sticker inside the driver’s side door jamb.
Will this part fix my specific problem?
This ECM is a guaranteed fix for a confirmed module failure. While it resolves the many symptoms listed above, it’s crucial to have your vehicle properly diagnosed. This part will not fix issues caused by faulty sensors, wiring, or other mechanical components.
Does this part come with a warranty?
Absolutely. This unit is backed by our one-year replacement warranty, giving you confidence in your repair.
Do I need to send my old computer back?
No core charge or return is required for this part. You can keep or recycle your old module.
